Primary Survey consists of identification and simultaneous management of life threatening conditions.
Resuscitation Phase
Secondary Survey does not begin until the primary survey (ABCDE) has been completed and the resuscitation phase has begun. The secondary survey is a head-to-toe evaluation of the casualty. It utilizes the look, listen, and feel techniques in a systematic total body/system evaluation (tubes and fingers in every orifice).
Treatment & Management
Primary Survey
I. Airway and C-spine control. The upper airway is assessed to determine patency. Maneuvers to establish a patent airway with the chin lift or jaw thrust must be aware of the possibility of a C-spine injury. A C-spine injury should be assumed in all patients, especially those with injuries above the clavicle and patients suffering from blast trauma.
A. The most important question to ask a trauma patient is "How are you"? No response implies an altered level of consciousness. Positive, appropriate verbal response indicates a patent airway, intact ventilation and adequate brain perfusion.
B. Maintain an intact airway, protect the airway in jeopardy and provide an airway when none is available. These principles must be applied assuming that a C-spine injury is present with:
1. Chin lift is accomplished with the fingers on one hand placed under the mandible, which is then gently lifted upward to bring the chin anterior. The thumb of the same hand lightly depresses the lower lip to open the mouth. The thumb may also be placed behind the lower incisors and, simultaneously, the chin gently lifted.
2. Grasping the angles of the lower jaw, one hand on each side, and displacing the mandible forward performs jaw thrust maneuver.
3. Oropharyngeal airway, the preferred technique is:
a. To use a tongue blade to depress the tongue and then insert the airway posteriorly.
The artificial airway must not push the tongue backward and block, rather than clear, the airway. This device must be not be used in the conscious patient because it may induce gagging, vomiting and aspiration.
b. The alternative technique is to insert the oral airway upside-down, so its concavity is directed upward, until the soft palate is encountered. At this point, the airway is rotated 180 degrees, the concavity is directed caudad, and the airway is slipped into place over the tongue. This method should not be used for children, because the rotation of the airway may damage teeth.
4. Nasopharyngeal airway is:
a. Inserted in one nostril and passes straight posteriorly and gently into the posterior oropharynx.
1) The nasopharyngeal airway is preferred to the oropharyngeal airway in the
responsive patients because it is better tolerated and less likely to induce vomiting.
5. Orotracheal intubation is for the unconscious patient who has sustained blunt trauma and the need for definitive airway is anticipated. The procedure for placement is:
a. Assure that adequate ventilation and oxygenation are in progress.
b. Inflate the cuff of the endotracheal tube to establish that the balloon does not leak, then deflate the cuff.
c. Connect the laryngoscope blade to the handle, and check the bulb for brightness.
d. Have an assistant manually immobilize the head and neck. The patient’s neck must not be hyperextended or hyperflexed during this procedure.
e. Hold the laryngoscope in the left hand.
f. Insert the laryngoscope into the right side of the patient’s mouth, displacing the tongue to the left and lift the jaw anteriorly.
g. Visually examine the epiglottis and then the vocal cords.
h. Gently insert the endotracheal tube the trachea without applying pressure on the teeth or oral tissues.
i. Inflate the cuff with enough air to provide an adequate seal. Do not overinflate the cuff.
j. Check the placement of the endotracheal tube by bag-valve-to-tube ventilation.
k. Visually observe lung expansion with ventilation.
l. Auscultate the chest and abdomen with a stethoscope to ascertain tube position.
m. Secure the tube. If the patient is moved, the tube placement must be reassessed.
n. If endotracheal intubation is not accomplished within the time required to hold your breath before exhaling, discontinue attempts, ventilate the pateint with a bag-valve-mask device, and try again.
6. Nasotracheal intubation or blind nasotracheal intubation is indicated for the conscious or breathing unconscious patient and is contraindicated in the apneic patient and whenever severe midface fractures or suspicion of basilar skull fracture exist. The procedures for a nasotracheal intubation are:
a. If a cervical spine fracture is suspected, leave the cervical collar in place to assist in maintaining immobilization of the neck.
b. Assure that adequate ventilation is in progress.
c. Inflate the cuff of the endotracheal tube to ascertain that the balloon does not leak, then deflate the cuff.
d. If the patient is conscious, spray the nasal passage with an anesthetic and vasoconstrictor to anesthetize and constrict the mucosa. If the patient is unconscious, it is adequate to spray the nasal passage only with a vasoconstrictor.
e. Have an assistant maintain manual immobilization of the head and neck.
f. Lubricate the nasotracheal tube with a local anesthetic jelly and insert tube into the nostril.
g. Guide the tube slowly but firmly into the nasal passage, going up for the nostril and then directly posterior and down into the nasopharynx. The curve of the tube should be aligned to facilitate passage along this curved course.
h. Once the tube has entered the pharynx, listen through the tube until the sound of the moving airflow emanating form the endotracheal tube. Advance the tube until the sound of the moving air is maximal, suggesting location of the tip at the opening of trachea. While listening to air movement, determine the point of inhalation and advance the tube quickly. If tube placement is unsuccessful repeat the procedure by applying gentle pressure on the thyroid cartilage. Remember to intermittently ventilate the patient.
i. If an endotracheal stylet is utilized, bend the lower end of the tube and stylet (approximately the last one-fourth) to a near 90o angle. As the tube is inserted, the end of the tube should be point to the ipsilateral ear. Be sure that the stylet is recessed approximately ½ inch from the end of the tube to prevent trauma during insertion. Gently, yet firmly, guide the tube into the pharynx, and through the glottis and vocal cords. Continue to advance the tube with gentle pressure as you withdraw the stylet.
7. Surgical cricothyroidotomy is indicated when there is an inability to intubate the trachea or a contraindication to intubation (severe maxillofacial injuries or larynx fracture). Performing a surgical cricothyroidotomy is accomplished by:
a. Place the patient in a supine position with the neck in a neutral position. Palpate the thyroid notch, cricothyroid interval, and the sternal notch for orientation. Assemble the necessary equipment.
b. Surgically prepare and anesthetize the area locally, if the patient is conscious.
c. Stabilize the thyroid cartilage with the left hand.
d. Make a transverse or longitudinal skin incision over the cricothyroid membrane.
Carefully incise through the membrane.
e. Insert the scalpel handle into the incision and rotate it 90o to open the airway. A hemostat also may be used instead of the scalpel handle.
f. Insert an appropriately sized, cuffed endotracheal tube into the cricothryoid membrane incision, directing the tube distally into the trachea.
g. Inflate the cuff and ventilate the patient.
h. Observe lung inflations and auscultate the chest for adequate ventilation.
i. Secure the endotracheal tube to the patient to prevent dislodging.
II. Breathing- Expose the patient’s chest and evaluate breathing. Assess respiratory movement and quality of respiration by observing, palpating, and listening. The signs of chest injury or hypoxia that are particularly important and often subtle include an increased rate of breathing and a change in the breathing pattern, especially toward progressively more shallow respirations. Cyanosis is a late sign of hypoxia in the trauma patient. The traumatic conditions that most often compromise ventilation are:
A. Tension pneumothorax develops when a "one-way-valve" air leaks occurs either from the lung or through the chest wall. Air is forced into the thoracic cavity without any means of escape, completely collapsing the affected lung. The mediastinum and trachea are displaced to the opposite lung. A tension pneumothorax requires immediate decompression and is managed initially by rapidly inserting a needle into the second intercostal space in the midclavicular line of the affected hemi-thorax.
B. Open pneumothorax (Sucking Chest Wound) is a large defect of the chest wall, which remains open, resulting in an open pneumothorax or sucking chest wound. Equilibration between intrathoracic pressure and atmospheric pressure is immediate. If the opening in the chest wall is approximately 2/3 the diameter of the trachea, air passes preferentially through the chest defect with each respiratory effort, because air tends to follow the path of least resistance through the large chest-wall defect. Manage an open pneumothorax by promptly closing the defect with a sterile occlusive dressing, large enough to overlap the wound’s edges, and taped securely on three sides. Taping the occlusive dressing on three sides provides a flutter-type valve effect. As the patient breathes in, the dressing is occlusively sucked over the wound, preventing air from entering. When the patient exhales, the open end of the dressing allows air to escape. A chest tube should be placed remote from the wound as soon as possible. Securely taping all edges of the dressing can cause air to accumulate in the thoracic cavity resulting in a tension pneumothorax unless a chest tube is in place. Any occlusive dressing (plastic wrap, petrolatum gauze, etc.) may be used as a stopgap so rapid assessment can continue.
Chest tube insertion:
1. Determine the insertion site; usually the nipple levels (5th intercostal space) anterior to the midaxillary line on the affected side. A second chest tube may be needed for a hemothorax or especially large pneumothorax.
2. Make a 2-3 cm transverse (horizontal) incision at the predetermined site and blunt dissect through the subcutaneous tissues, just over the top of the rib (nerves and arteries run inferior to ribs).
3. Puncture the pariental pleura with the tip of a clamp and put a gloved finger into the incision to avoid injury to other organs and to clear any adhesions or clots.
4. Clamp the "suction" end of the thoracostomy tube (minimum #38 French in the adult) and advanced the "drainage" end of the thoracostomy tube into the pleural space to the desired length.
5. Look for "fogging" of the chest tube with expiration or listen for air movement.
6. Connect the "suction" end of the thoracostomy tube to the heimlich valve.
7. Suture the tube in place.
8. Apply a dressing, and tape the tube to the chest.E. Cardiac Tamponade most commonly results from penetrating injuries. Blunt injury also may cause the pericardium to fill with blood from the heart, great vessels, or pericardial vessels. The human pericardium sac is a fixed fibrous structure, and only a relatively small amount of blood required to restricted cardiac activity and interfere with cardiac filling. Removal of small amounts of blood or fluid, often as little as 15 ml to 20 ml, by pericardiocentesis may result in immediate hemodynamic improvement. The classic Beck’s triad consist of venous pressure elevation, decline in arterial pressure, and muffled heart tones. Pericardiocentesis is indicated for patients who do not respond to the usual measures of resuscitation for hemorrhagic shock and who have the potential for cardiac tamponade.
The procedure for a pericardiocentesis is:
1. Using a #16 or #18 gauge, 6 inch (15 cm) or longer over-the-needle catheter, attach a 35-ml empty syringe with a three-way stopcock.
2. Puncture the skin 1 to 2 cm inferior to the left of the xypho-chondral junction, at a 45o angle to the skin.
4. When the needle-tip enters the blood filled pericardial sac, withdraw as much nonclotted blood as possible.
5. After inspiration is completed, remove the syringe, and attach a three-way stopcock, leaving the stopcock closed. Secure the catheter in place.
6. Should the cardiac tamponade symptoms persist, the stopcock may be opened and the pericardial sac reaspirated. The plastic pericardiocentesis needle can be sutured or taped in place and covered with a small dressing to allow for continued decompression en route to surgery or transfer.
III. Circulation

D. More detailed evaluation is done during the secondary survey.
V. Exposure/Environmental control:
A. Patient should be completely undressed to facilitate a through examination and assessment
of the patient (cutting clothing in accordance with [IAW] pages 38-39).
B. Iatrogenic Hypothermia.
2. IV fluids must be warmed before administering to the patient if environmental
conditions are cold/wet (see page 23).
Resuscitation Phase
I. After the primary survey is completed, and especially after an adequate airway has been established, the resuscitation phase begins. Hypovolemia and shock (in trauma) is almost always due to blood loss. Access to the circulation for crystalloid therapy or blood resuscitation is mandatory.
A. IV’s locations order of preference: Forearm/antecubital, Saphenous, Femoral, Jugular and then the Subclavian.
B. Crystalloid resuscitation is accomplished utilizing isotonic electrolyte solutions is used for initial resuscitation. This type of fluid provides transient intravascular expansion and further stabilizes the vascular volume by replacing accompanying fluid losses into the interstitial spaces. Ringer’s lactate solution is the initial fluid of choice. Normal saline is the second choice.
4. Patient’s response to initial fluid resuscitation is the key to determining subsequent therapy.
a. Rapid responses the patient responds and remains stable as fluids are slowed indicates a Class I or less hemorrhages without ongoing losses; no furthers fluid bolus or blood required, but continue with maintenance IV fluid.
b. Transient response is an initial response but subsequent deterioration indicates a Class II-III hemorrhage and on-going losses; continued fluid administration and initiation of blood transfusion are indicated.
c. Minimal or no response indicates a Class IV hemorrhage with or without ongoing loss; rapid blood administration and surgical intervention are needed; also consider error in diagnosis (tension pneumothorax, peri-cardial tamponade, or cardiogenic shock).

Secondary Survey
A Head-to-Toe Evaluation
I. The Secondary Survey does not begin until the Primary Survey (ABCDE) is completed, resuscitation is initiated, and the patient’s ABCDEs are reassessed. Secondary Survey consists:
A. Head is checked for scalp and bony structures for lacerations, contusions and evidence of fractures.
B. Ears are checked for Battle’s sign (blood or clear fluids in the ear or bruising behind the ears) which indicate a basilar skull fracture (protect the cervical spine).
C. Eyes are checked for Raccoon and eye (periorbital bruising) which indicates a cribiform plate fracture. Also check the visual acuity (have the patient read the words on a IV bag or 4 x 4 dressing package), hemorrhages, penetrating injuries, contact lenses and dislocation of lenses.
D. Nose is checked for bleeding and cerebrospinal fluid. Do not place anything in the patient’s nostrils if blood or cerebrospinal fluid is present.
E. Mouth is checked for loose or foreign bodies, teeth, vomitus and bleeding or cerebrospinal fluid.
F. Neck. Patients with maxillofacial or head trauma should be presumed to have an unstable cervical spine injury, and the neck should be immobilized with sandbags (socks filled with sand and dirt) and taped to secure the cervical spine. Cervical spine is inspected for tenderness, stair step deformities, subcutaneous emphysema, tracheal deviation, laryngeal fracture and dilated neck veins.
G. Chest is visual examined ensuring that the front and back are covered (which will identify must-penetrating trauma). Sucking chest wounds must be covered with Vaseline gauze or treated with a chest tube insertion. Evaluation of ventilatory function is best performed utilizing the stethoscope. A quick check of the neck veins is useful in the assessment of cardiac tamponade.
H. Abdomen is checked for bowel sounds (5-34 per minute), guarding, masses and evidence of trauma.
I. Perineum/Rectal/Vagina is checked for urethral bleeding, blood in the scrotum, pregnancy, blood in the vaginal vault and vaginal laceration. A digital exam is performed to assess for presence of blood within the bowel lumen, a high riding prostate, presence of pelvic fractures and quality of sphincter tone.
J. Musculoskeletal system.
1. Tenderness, crepitation, abnormal movements along the shafts will identify fractures and for peripheral pulses.
2. Pelvis is checked for continuity with anterior and posterior pressure with the heels of the hands on both the anterior iliac spines and symphysis pubis.
3. Blood loss in fractures can be estimated:

A. Ensure that AMPLE, vital signs and Glascow Coma Score on the remark section (line #32) of the DD Form 1380 (casualty card).
B. Re-evaluated the trauma patient constantly to ensure that new findings are not over looked, and to discover deterioration in previously noted symptoms.
C. Ensure meticulous record keeping since more than one provider will be participating in the care of the patient along the evacuation chain.
Triage
Emergency War Surgery, 1988
I. The likely outcome of the individual casualty must be factored into the decision process prior to the commitment of limited medical resources. Casualties are generally sorted into five categories or priorities; these groupings are discussed in decreasing order of surgical urgency.
A. Urgent group requires urgent intervention if death is to be prevented. This category includes those with asphyxia, respiratory obstruction from mechanical causes, sucking chest wounds, tension pneumothorax, maxillofacial wounds with asphyxia or where asphyxia is likely to develop, exsanguinating internal hemorrhage unresponsive to vigorous volume replacement, most cardiac injuries, and CNS wounds with deteriorating neurological status.
B. Immediate category is those casualties that present severe, life-threatening wounds that require procedures of moderately short duration. Casualties in this group have a high likelihood of survival. They tend to remain temporarily stable while undergoing replacement therapy and methodical evaluation. The key word is temporary. Examples of the immediate category are unstable chest and abdominal wounds, inaccessible vascular wounds with limb ischemia, incomplete amputations, open fractures of long bones, white phosphorous burns, and 2nd and 3rd degree burns of 30-40% or more of the total body surface area.
C. Delayed category is casualties that can tolerate delay prior to operative invention without unduly compromising the likelihood of a successful outcome. When medical resources are overwhelmed, individuals in this category are held until the urgent and immediate cases are cared for. Examples are stale abdominal wounds with probable visceal injury, but without significant hemorrhage. Other examples include soft-tissue wounds requiring debridement, maxillofacial wounds without airway compromise, vascular injuries with adequate collateral circulation, genitourinary tract disruption, fractures requiring operative manipulation, debridement, external fixation, most eye and CNS injuries.
D. Minimal or Ambulatory category is comprised of casualties with wounds that are so superficial that they require no more than cleansing, minimal debridement under local anesthesia, tetanus toxoid and first-aid type dressings. They must be rapidly directed away from the triage area to uncongested area where first aid and non-specialty medical personnel are available. Examples include burns of less than 15% total body surface area (with the exception of those involving the face, hands or genitalia). Other examples include upper extremity fractures, sprains, abrasions, early phases of symptomatic but unquantified radiation exposures, suspicion of blast injuries (perforated tympanic membranes).
E. Expectant category are those casualties that have wounds that are so extensive that even if they were the sole casualty and had the benefit of optimal medical resource application, their survival still would be very unlikely. The expectant casualties should be separated from the view of other casualties; however, they should not be abandoned. Above all, medical personnel attempt to make them comfortable by whatever means necessary. Examples are unresponsive patients with penetrating head wounds, high spinal cord injuries, mutilating explosive wounds involving multiple anatomical sites and organs, 2nd and 3rd degree burns in > 60% total body surface area, convulsions and vomiting within 24 hours of radiation exposure, profound shock with multiple injuries, and agonal respirations. At least one medic should constantly attend to the care of the expectant categories.
II. Triage location should:
A. Be positioned as far forward as the tactical situation permits, and should be co-located with organic or attached /OPCON security elements.
B. Have enough space to accommodate multiple vehicles.
C. Be on high ground with good drainage.
D. Have evacuation routes with easy to and from roads or trails. If time permits route
Should be marked or have ground guides.
E. Have a MEDEVAC LZ within 100-150 meters.
III. Operations:
A. Upon arrival all casualties will be re-triaged. This will be done by either the most senior medical personnel or as designated by the senior medical person.
1. All casualties are logged in on an Admissions/Disposition roster.
2. All casualties have a DD Form 1380 (casualties feeder card) on them, and that the card is filled out correctly.
C. Mass casualties:
2. The battalion aid station (BAS) will be notified as soon as possible (ASAP) of all mass
Casualty situations so that it can properly prepare personnel and equipment.
3. Non-organic medical vehicles that are used for the evacuation of patients will be manned with a medic or a CLS.
IV. Triage color code for chem-lights are:
At no time should the normal progression of care or casualty flow be allowed to have a
reverse direction. Traffic should not enter and exit through the same portal. Flow against the grain must be held to an absolute minimum. Above, all the dead must not be introduced into the triage area.

Medical Evacuation Precedence
I. Urgent is assigned to emergency cases that should be evacuated as soon as possible and within a maximum of two hours in order to save life, limb or eyesight. This group requires urgent intervention if death is to be prevented. This category includes those with asphyxia, respiratory obstruction from mechanical causes, sucking chest wounds, tension pneumothorax, maxillofacial wounds with asphyxia or where asphyxia is likely to develop, exsanguinating internal hemorrhage unresponsive to vigorous volume replacement, most cardiac injuries and CNS wounds with deteriorating neurological status.
II. Priority is assigned to sick and wounded personnel requiring prompt medical care. This precedence is used when the individual should be evacuated within four hours or his medical condition could deteriorate to such a degree that he will become an Urgent.
III. Routine is assigned to sick and wounded personnel requiring evacuation but whose condition is not expected to deteriorate significantly. The sick and wounded in this category should be evacuated within 24 hours.
IV. The determination to request MEDEVAC and assignment of MEDEVAC the senior military person present makes precedence, based on the advice of the senior medical person at the scene.

Chemical Agents
Medical Management of Chemical Casualties Handbook, Sept. 95
I. Nerve Agents (GA/Tabun, GB/Sarin, GD/Soman, GF, VX) mechanism of action inhibits the enzyme acetylcholinesterase is to break down or destroy the chemical acetylcholine. Acetylcholine is a neurotransmitter or messenger chemical, that is released by a nerve to stimulate another nerve, gland or muscle. Under normal conditions, when the required action at each step is completed, the acetylcholine is broken down by the acetylcholinesterase thus stopping the action. But when a nerve agent inhibits acetylcholinesterase, this enzyme can not perform its normal function of breaking down or hydrolyzing the acetylcholine. Acetylcholine is not destroyed and it accumulates along the nerve path; the target organ’s action continues uncontrolled with serious impact to the poisoned person. Muscles become hyperactive and twitch uncontrollably and glands secret copiously.

3. Hypochlorite.
4. Large amount of water.
5. M295.
F. Treatment:
1. Atropine is the drug of choice for treating nerve agent poisoning. Atropine will dry secretions, reduce bronchoconstriction and decrease gastrointestinal motility. Atropine will have no effect on miosis and will not affect skeletal muscle abnormalities.
a. Mild symptoms such as rhinorrhea, slight or recovering breathing difficulty or excessive salivation are usually managed with one Mark I. Pain in the eyes, twitching of the eyelids, redness and miosis can be controlled with atropine eye drops.
b. Severe symptoms usually consist of two or more major systems (gastrointestinal, skeletal muscle, respiratory, etc.); the first step is to administer all three Mark I’s and Diazepam. Diazepam (CANA) should always be administered, when three Mark I’s is given together.
c. Administer 2 mg of Atropine every five minutes until secretions decrease or until the casualty is breathing easier. A total of 15-20 mg of atropine in the first three hours of the onset of symptoms may be needed.
d. Atropine administered with the autoinjector will show some effectiveness in three-five minutes.
e. Discontinue atropine when secretions of the mouth, nose and lungs are minimized.
2. Pralidoxime Chloride (2-PAMCL) in the autoinjector (600-mg/2 cc) is the second drug for use in nerve agent poisoning cases. The 2-PAMCL removes nerve agent from the enzyme acetylcholinesterase as long as irreversible bonding (aging) has not occurred. 2-PAMCL must be used as early as possible, which is why the 2-PAMCL was included in the Mark I. Only three 2-PAMCL can be given every hour. Discontinue use of the 2-PAMCL after symptoms of respiratory distress have eased.
3. Diazepam or CANA (Convulsive Antidote Nerve Agent) comes as a 10 mg autoinjector adopted by the US military for use in controlling convulsing patients. The key to increasing the effectiveness of the Diazepam is that it must be used before convulsions begin. When two or more organ systems become involved, one Diazepam injector should be administered along with the three Mark I’s to lessen the convulsive activity the soldier may experience. If patient is still convulsing after 10 minutes give a second Diazepam injector. If still convulsing after 5-10 minutes give a third Diazepam autoinjector.
4. Aggressive airway maintenance and the use of assisted ventilation will increase the casualties with severe symptoms will require ventilator support.
5. Pyridostigmine Bromide (P.B. tabs) pretreatment was adopted primarily for use against GD nerve agent’s "aging" effect on acetylcholinesterase. The pretreatment has no effect on someone exposed to the nerve agent GB, GF or VX does not increase the effectiveness of the treatment for these agents. Within two minutes after GD inhibits acetylcholinesterase, the GD becomes irreversibly bound (aging) to the enzyme and can not be stripped off the enzyme by the oxime 2-PAMCL in the Mark I.
a. The dosage of 30 mg of pyridostigmine is the maximum concentration within the body, will reversibly inhibit approximately 30% of the blood’s acetylcholinesterase. A level lower than the maximum will be consistently maintained al long as the eight-hour oral dosage is continued. The pretreatment taken by itself will not protect the soldier and does not reduce the effects from the nerve agent.
b. The pretreatment is not an antidote, but when used in conjunction with the Mark I, the pyridostigmine enhances the effects of the Mark I only against GD. Each package is a blister pack of 21 tablets with each tablet containing 30 mg of pyridostigmine.
c. On order, one tablet is taken orally every eight hours. If a scheduled dose is missed
it will not be made up; the soldier will take one tablet at the earliest opportunity to begin the next eight-hour interval. The soldier will discontinue taking the tablets on order from their unit commander. The pretreatment should not be taken on a continuous basis for longer than 14 days. The pretreatment should only be started upon on order of the unit commander.
II. Mustard (HD and H) and Lewisite (L) are mustards that rapidly penetrates the skin causing both cellular damage and systemic damage. The true deadly nature of the agent’s effects is that any individuals exposed to large amounts of mustard in either liquid or vapor form, faces a total systemic assault. Death occurs because of the failure of the body’s immune system (sepsis and infection are the major contributing causes to death) and pulmonary damage.
A. Detection is made with:
2. Skin blisters the size of a quarter or smaller should be left intact if possible. Large blisters should be deroofed with blisters which have broken should have the ragged roof of the blister removed. The area of the open blister should be cleaned with tap water or saline and a petrolatum gauze bandage applied. The individual should be given a tropical antibacterial cream such as sliver sulfadiazine burn cream and instructed to apply a 1/8-inch layer to the blister (s) four times per day. A petrolatum gauze bandage must cover the area.
3. The individual who presents with any sign or symptom of respiratory exposure must be evacuated promptly.
III. Cyanide (AC and CK) is a blood agent with the basic physical action of disrupting oxygen utilization at the cellular level.
A. Detection is made only with the M256A1.

Field Management of Contaminated Casualties
Medical Management of Chemical Casualties Handbook, Sept. 95
I. Key Elements for planning:
1. An entry control point (ECP) must be established to control movement of all vehicles
into the Medical Decontamination and Treatment Facility (MTF).
2. The ECP should be located at a distance far enough from the MTF to minimize any vapor hazard that may occur from contaminated vehicles stopping at this point.
D. Equipment and supplies.
E. Personnel requirements.

|
***Never used with a blister agent*** |
III. Establish the treatment site:
A. Outside a one kilometer stand off distance from the edge of the predicted downwind hazard area that:
2. One soldier will be in MOPP 4 conducting continuous monitoring during site set up.
This soldier should use both the M8A1 (ACAA) and the M256A1 chemical detection kit regardless of what agent has been reported.
3. As long as the monitor continues to report no contact with chemical agent vapors, all
B. If the selected site is within the one kilometer stand off distance or within the predicted downwind vapor hazard area, then:
1. All personnel must be in MOPP 3 or MOPP 4 during site set up.
2. If the site must be set up inside the vapor hazard area, it is critical that the selected site be free of liquid contamination.
3. As long as the team sent to the selected site remains completely outside the predicted liquid hazard area, and optimally outside the stand off distance, then a point chemical survey should take no longer than a few minutes using the M8 chemical paper.
IV. Site preparation phase:
B. All vehicle movement routes must be driven and points along the route requiring direction
indicators identified and any ground obstacles identified for removal.
C. The arrival/triage area must be surveyed to insure it can handle the evacuation vehicles
moving into and out of the area plus the activities of the triage officer and the litter teams.
D. Site must be evaluated for night operations.
E. When setting up in a forest location, it may become necessary to clear low hanging branches, brush or other ground obstacles.
F. Only the minimum amount of medical supplies needed to support the contaminated emergency treatment point should be set out.
G. The emergency treatment area and litter decontamination area will need:
Emergency Treatment Area Equipment
Item #9; #9; Amount
Litter Decontamination Area Equipment
Item #9; #9; Amount
V. Emergency medical treatment will consist of:
A. Administration of Mark 1’s and Diazepam.
B. Application of pressure dressings.
C. Establishing a patent airway.
D. Starting an intravenous infusion.
E. All personnel rendering medical assistance will be in MOPP IV.
VI. Chloride solution:
A. 0.5% chlorine solution is used for all skin decontamination.
B. 5% chlorine solution is used to decontaminate the casualty’s protective mask, hood, scissors, TAP aprons, litters and the gloves on personnel working in the patient decontamination area plus litters.
C. The buckets should be marked to indicate 0.5% and 5% chlorine solution.
D. Preparation of the 0.5% and 5% hypochlorite solutions will require mixing the solutions in a container which can be closed after completion. By closing the container the solution will remain at the required strength far longer than if allowed to stand in an open container. The recommended mixing container is the five-gallon water can. When mixing the calcium hypochlorite granules, the granules must be completely dissolved into the water. The most effective method for mixing is to agitate the granules as they are poured into the water and then allow the solution to sit for 20 minutes to ensure the granules are dissolved.
E. For the 0.5% hypochlorite solution:
1. Use 6 ounce bottles of calcium hypochlorite granules found in the Chemical Agent Patient Decon MES and mix one of the six ounce bottle into five gallons of water.
2. When using a bulk package of calcium hypochlorite from a bulk package, retain one empty six ounce bottle from the Chemical Agent Patient Decon MES to measure the correct amount of dry calcium hypochlorite granules (mix as listed above).
3. Household bleach (Clorox or Purex) use two quarts with four and half gallons of water.
F. For the 5% hypochlorite solution:
1. Use six ounce bottles of the calcium hypochlorite granules and mix eight of the six ounce bottles of calcium hypochlorite into the five gallon container of water.
2. If using calcium hypochlorite from the bulk package retain one of the empty six ounce bottles to measure the correct amount of dry calcium hypochlorite granules.
3. Household bleach (Clorox or Purex) use the bleach straight from the bottle, do not mix with water.
VII. Clothing removal:
1. Cover inlet valve covers to prevent wetting by the 5% chlorine solution.
2. Sponge down the voicemitter, eyelets outserts, sides and top of the hood with the 5%
chlorine solution.
3. When the 5% chlorine solution is not available, use the M291 SDK or the M258A1 SDK reversing the order of the wipes, wipe number two then wipe number one.
4. Immerse and scrub scissors in a 5% chlorine solution. After ever two to three cuts, the scissors must be immersed, along with the gloved hands of the soldier doing the cutting.
5. Cut the zipper cord, neck draw cord and then the hood shoulder straps.
7. Cut the zipper below the voicemitter.
8. Proceed cutting upward towards the inlet valve covers. Cut close to the covers and
proceed towards the eyelets outsert.

2. After the casualty is lifted up the casualty is rolled slightly inward against the lifters’ chest to make holding up the casualty less of an effort. If decontaminatable litters are not available, use a plastic covered canvas litter (or at a lesser degree of desirable, a single use of an uncovered canvas litter).
XIV. Skin and wound decontamination:
A. Decontaminate the casualty entire skin surface by lightly wiping the skin with a sponge with 0.5% chlorine solution.
B. The casualty is washed from the midline outward constantly washing from clean to dirty and not placing a dirty sponge back on a clean area without first rinsing it in the 0.5% chlorine solution.
C. The complete topside of the casualty is washed in this manner paying particular attention to hairy areas of the body (the groin and axillary regions) and sweaty area; i.e. the belt-line, just above the boots and the crease of the buttock and wrists.
D. The backside of the casualty will be washed after the casualty is log rolled onto their side.

II. A review of infections following soft-tissue limb wounds in soldiers injured during the Falkland Campaign indicated that a delay in surgery and a delay in antibiotic administration were the most important factors related to the subsequent development of infection. When surgical delay was unavoidable, the delaying antibiotic administration assumed an even greater importance. That study showed a greater incidence of septic complications when debridement was delayed more than six hours; it also showed an increased incidence of infectious complication when the time from wounding to antibiotic administration exceed six hours.

Tetanus Immunization
I. Previously immunized individuals.
A. A fully immunized individual is an individual that the attending physician/physician assistant has determined to have been previously and fully immunized, and the last dose of toxoid was given within the last ten years. Treatment consists of:
1. Administered 0.5 ml of absorbed toxoid for tetanus-prone wounds (if more than five years has elapsed since the last dose).
injections of toxoid and the last dose was received more than ten years ago, 0.5 ml absorbed toxoid is administered for both tetanus-prone and none tetanus-prone wounds. Passive immunization is not necessary.
II. Individuals that are not adequately immunize are those patients that have received:
Tetanus remains unproved).
III. Immunization schedule for adults:
B. Booster every 10 years.
Fractures
I. Types of fractures:
1. Type I with the wound < 1 cm long with no evidence of contamination.
2. Type II with the wound > 1 cm long with no soft tissue stripped from the bone.
3. Type IIIA with a large wound with adequate soft tissue coverage of bone.
Closed fracture with #9; #9; Open fracture with Intraarticular fracture
large hemotoma #9; #9; external bleeding #9; #9; with hemarthrosis
II. Fracture patterns:
the shaft of a long fracture.
G. Avulsions fracture results from a sudden muscle pull that tears the musculotendinous
with attached bony fragment from the bone.
Segmental #9; #9; Impacted Avulsion
III. Principles of splinting:
A. A dry, sterile compression dressing is applied to all open wounds to control bleeding and prevent further contamination, minimizing the risk of infection.
B. The splint should incorporate the joints above and below the fracture bone and splint the fracture in place.
C. Splinting demands constant monitoring of neurovascular function of distal limb (capillary refill, pulse, gross sensation and motor function).
E. If fracture causes significant deformity of long bone (i.e. femur), limb may be realigned
with gentle traction and maintained in this position during splinting.
IV. Fractures of the upper extremities:
A. Shoulder injuries:
1. Most injuries around the shoulder (including acromioclavicular separations) as well as
fractures of the clavicle, proximal humerus, and scapula, can be immobilized with a sling and swathe. The elbow should be well supported in the sling and the knot tied securely to one side of the neck. One or two swathes are then applied over the arm in the sling to bind the arm firmly, but not to tightly, to the chest wall, preventing the limb from swinging freely. The hand is left free to facilitate monitoring of the neurovascular function of the limb.
Position of arm & forearm #9; #9; Immobilization technique
2. The only shoulder injury that cannot be effectively immobilized in a simple sling and swathe is the common anterior dislocation of the shoulder joint. Following this injury, the arm is locked in moderate abduction and cannot be brought comfortably against the chest wall (as is needed for the application of a simple sling and swathe). An anteriorly dislocated shoulder must be splinted in the abducted position in which it is found.
B. Humerus fractures. Following fracture of the shaft of the humerus, muscle spasm often produces a significant deformity. If angulation is apparent, applying longitudinal traction to the distal fragment can restore the general alignment of the arm. This is best accomplished by grabbing the condyles of the humerus with one hand, supporting the fracture site with the other hand, and gently but firmly pulling the arm distally until the arm is aligned against the chest wall. One person must maintain this alignment while a padded board splint is applied, adding stability to the lateral aspect of the arm. The entire injured limb and the splint are then incorporated into a sling and swathe.
C. Injuries of the elbow range from non-displaced fractures to complete dislocations and severe limb-threatening injuries, such as the displace supracondylar fracture. The injured elbow must be splinted in the position in which it is found because manipulation or application of traction in this region may cause or aggravate a preexisting nerve or vessel injury. A Sam splint with an ace wrap, and the splinted limb is then supported with a sling.
D. Forearm and hand fractures:
1. Although significant angulation often occurs, most of these fractures can be well stabilized with an air splint without manipulation or traction. An air splint gently compresses the injury site and effectively immobilizes the fracture fragments. Two individuals are needed to apply an air splint properly:
a. One to support the injured limb at all times.
b. The other to put on the splint.
c. The splint is inflated once it is in place.
2. Wrist and hands injuries can be immobilized with a bulky hand dressing and a palmar padded board splint. Injured hands are placed in the position of function, with the wrist dorsiflexed about 30 degrees and the fingers flexed slightly into a position that would comfortably hold softball. A roll of soft gauze is then placed in the palm of the hand, and a Sam splint is placed along the palmar aspect of the hand, wrist and forearm. The entire limb below the elbow is secured to the Sam splint with an ace wrap. While the patient is being transported the splinted hand should be elevated in a sling.
V. Fractures of the lower extremities:
A. Hip fractures. Displaced hip fractures cause an obvious shortening and external rotation of the injured limb. Because the fracture lies so close to the hip joint, the pelvis as well as the entire leg should be immobilized to prevent movement at the fracture site. A long board or a scoop stretcher provides support and stabilizes the pelvis and the entire injured limb.
B. Femur fractures. Fracture of the femoral shaft usually occurs as the result of a high-velocity injury. Muscle spasm and the loss of stability of the underlying femur usually create significant deformity. Traction splints are used for fractures of the femoral shaft:
1. First, the limb is realigned with manual traction by one medic.
2. Another medic places the traction splint under the injured limb, secures it with straps, and uses a ratchet mechanism to maintain the needed continuous traction on the ankle and foot.
3. Patients with femoral fractures may also have associated pelvic or spinal injury and therefore should be transported on a spine board.
C. Injuries to the knee range from ligament sprains or ruptures to severe fracture/dislocations. Because the risk of neurovascular injury is extremely high in this region, the injured knee must be splinted in the position in which it is found.
1. When the knee is found extended, two padded boards splints (one on the medial and one on the lateral aspects of the injured limb) from the groin to the ankle joint, secured with several cravats; provide adequate immobilization of the knee joint.
2. When the knee is found in the flexed position, padded board splints are placed on the medial and lateral aspect of the limb in a "A" frame configuration. The splints should extend from the upper end of the femur to the lower end of the tibia.
C. Tibia and fibula fractures are often associated with significant deformity. Severely displaced fractures of the tibia and fibula should be realigned with longitudinal traction and splinted with a long leg air splint or padded board splints that extend above the knee. The knee joint must be completely immobilized.
D. Ankle and foot fractures. The pillow splint is one of the many splinting devices used to immobilize an injured ankle or foot. A standard pillow can be wrapped around the injured ankle and foot and secured snugly with safety pins or an ace wrap. The pillow readily conforms to the shape of the injured part. Toes are exposed for assessment of distal neurovascular function.
VII. Fractures of the spine:
A. Complete immobilization of the injured spine prior to transportation to the hospital has significantly reduced the incidence of quadriplegia and paraplegia following major trauma. Proper splinting of the unstable spine greatly decreases the risk of spinal cord impingement by the unstable bony elements. Splinting is mandatory for all patients with a suspected spinal injury (i.e. patients involved in motor vehicle accidents, falls from a height that are hard like a helicopter landing or those with either face or head injuries).
1. The only indication for realignment of the injured spine is an inadequate airway, which is a life-threatening problem and therefore always takes precedence in the initial patient care protocols.
2. The purpose of spinal immobilization is to provide a single solid unit of the head, trunk and pelvis so that one segment does not move in relation to the other two.
3. A cervical collar is first placed on the cervical spine to provide initial and partial immobilization, however, a cervical collar alone cannot completely eliminate movement of the head and truck.
4. The trunk and then the head are secured to the immobilization device with straps.
5. The patient is rotated as a unit, laid on a long spin board, and secured to it with long straps.
6. After the head, spine and pelvis are fully immobilize, other limb injuries are splinted as well, and the patient is transferred on a long board.
7. Be sure the patient can be rolled as a unit to clear the airway since vomiting is a common reaction following a back fracture.
VIII. Fractures of the pelvis. Because the pelvis lies in the retroperitoneal space, in close proximity to several large blood vessels, pelvic fractures may lead to hypovolemic shock. The MAST and long board are most effective for immobilization of the pelvis and preventing hypovolemia. Inflation of the MAST stabilizes the pelvic fracture and decreases bleeding at the fracture sites. Sections of the MAST are inflated gradually while the patient’s blood pressure is continually monitored. Because severe, irreversible hypovolemic shock may ensue when a MAST is deflated, deflation should take place in a trauma center (i.e. a Level II medical company or combat support hospital).
SAMr Splint
I. The secret to using the SAM Splint properly is to curve it lengthwise. The longitudinal bend gives the splint its strength.
II. Double the SAM Splint or
create a t-bend for extra strength.
III. Curve the outside edges the opposite
direction to make it even stronger.
IV. Fold the SAM Splint around the thumb and over the wrist to stabilize thumb injuries.
V. Place the curved splint
under the forearm to treat
a lower arm fracture or sprain.
VI. Wrap the SAM Splint around the
elbow to splint the wrist or forearm.
VII. For injuries to fingers, fold up
the end for extra protection.
IIX. For dislocated shoulders, fold the splint
in threes to form a triangular ‘Airplane’ splint. Create
curves to strengthen.
IX. To splint the upper arm, double-fold one
end, and shape as a cup to support the elbow.
Use gauze, kling or wrap to keep the splint securely
in place. Finish with a sling or ace wrap to provide additional support.
X. Stabilize the ankle with a single splint, folded
under the foot, and applied to each side of the leg. Use
two splints, one on each side of the leg, and curve under
the foot to immobilize the knee or leg.
XI. Use the SAM Splint as a cervical collar if one is not available.
A. Begin by making a bend at one end; flare the upper end to support the chin.
Around the neck, bringing it obliquely down to the chest.
C. Squeeze in the sides to create lateral wings for stability and to take up the slack.
Burn Injuries
I. The first priority in the management of the burn patient is maintenance of the airway, control of hemorrhage, and prompt institution of resuscitative therapy (ABCDE).
B. The patient is not undressed unless the injury has been caused by a chemical agent, in
which case all contaminated clothing must be removed.
C. The patient should be covered with a clean sheet and a blanket, if appropriate, to maintain body temperature and prevent gross contamination during transport to a treatment facility. Burn dressings can be used or initial wound coverage.
D. Patency of the airway is assured.
E. Hemorrhage should be controlled.
F. Fractures should be splinted.
G. Intravenous pathway should be established in a unburned are (if available) and in an
upper extremity veins if there are associated abdominal wounds. A burn area may be used.
H. Patients with extensive partial-thickness burns may have considerable discomfort, which can be relieved by appropriate doses of morphine or meperidine administered intravenously. Subcutaneous or intramuscular injections of analgesics should not be used since they will not be
mobilized during the period of edema formation (and will therefore be ineffective in pain control).

To estimate the extent of irregularly disposed burns, on can make use of the fact that one surface of the casualty’s hand represents approximately 1% of his total body surface. Small burns of the face, hands, feet and perineum will require hospitalization, even if these limited areas are the only sites of a burn injury.

II. Resuscitation of burns:
A. Parkland Formula is the total fluid replacement required during the first 24 hours is percent of body burned x body weight in kilograms x 4 milliliters. Replace with lactated Ringer’s solution over 24 hours.
5040 ml; give 2500 ml over the first eight hours, then 1250 ml each eight hours period thereafter.
B. Determining an IV rate:
1. Maxi drip is 10 drops per minute thus:
a. 10 drops per min would give you 60 ml per hour.
b. 16 drops per min would give you 100 ml per hour.
a. Dividing the 2500-ml by eight (hours) is 312.5 ml per hour.
C. Urine output should be 30-50 ml in-patients weighing more than 30 kilograms or 1-ml/kg/hr in-patients weighing less than 30 kilograms.
Cold Injuries
Emergency War Surgery, 1988
I. The type of cold injury incurred is dependent upon the exposure temperature, the duration of exposure, and other environmental factors (such as wind and water) which intensify the effect of the temperature. On exposure to cold, there is an initial peripheral vasoconstriction in an attempt to conserve core heat. This vasoconstrictive episode, which is of short duration, is overcome by a physiologic protective mechanism termed cold-induced vasodilation (CIVD). CIVD intervenes to cause arteriovenous shunting to the skin. This allows relatively large volumes of blood to flow through cold extremities. Repeated cold weather exposures are said to improve this CIVD response, but it may be suppressed or absent when the individual is chilled, frightened, exhausted or malnourished. This mechanism appears to be blunted in blacks and perhaps other races.
II. Types of cold injuries:
A. Frostbite is due to freezing of tissue from intracellular ice crystal formations and microvascular occlusion. Similar to thermal burn, frostbite is classified into:
1. First degree is hyperemia and edema without skin necrosis.
2. Second degree is vesicle formation accompanies the hyperemia and edema with
partial thickness necrosis of skin.
3. Third degree is full thickness skin necrosis occurs, with necrosis of some underlying subcutaneous tissue.
4. Fourth degree is full-thickness skin necrosis, including muscles and bone with gangrene.
B. Nonfreezing injury is due to micorvascular endothelial damage, stasis and vascular occlusion. Trenchfoot and immersion foot is essentially the same injury, the major difference being the temperatures involved and the duration of exposure. The colder it is, the shorter the duration necessary to produce trenchfoot, whereas the longer the duration and warmer the temperature, the most likely one is to develop an immersion foot injury. The average duration of exposure may range from a few hours to many days. With ambient temperature above freezing, prolonged exposure leads to:
1. Chilblain’s frequently affects the hands as well as the feet, may result from exposure to air temperatures from just above freezing to as high as 60o Fahrenheit; is more likely to occur in dry, cold, windy air; but can also be associated with high humidity. It is not of major clinical significance in military operations.
2. Immersion foot implies an injury caused by exposure (usually in excess of 12 hours), to water temperature of about 50o Fahrenheit. This injury is common in wet jungles and in exposed life rafts.
3. Trench foot, which may also occur in the hands, results from prolonged exposure to cold at temperatures ranging from just above freezing to 50o Fahrenheit, often in a damp environment, and usually in connection with immobilization and dependency of the extremities. The blunt trauma of walking on wet feet hastens this injury.
C. Hypothermia is a state in which the patient’s generalized core temperature drops below 94o Fahrenheit (35o Celsius). This life-threatening, non-freezing cold injury is usually the result of either long-term exposure to cold air or immersion in cold water. It should be noted that freezing temperatures are not necessary to produce hypothermia, because wind, rain and cool temperatures increases body heat loss significantly.
III. Host factors:
A. Age, there is no convincing evidence that age is a significant factor in cold injury among combat troops.
B. Smoking, there is very clear evidence that the vasoconstrictor action of nicotine causes increased cooling of the extremities and an increase likelihood of frostbite. A significant number of severe injuries in military populations occur in heavy tobacco users.
D. Fatigue in both physical and mental weariness contribute to apathy which leads to neglect
of all acts except those vital to survival. Fatigue is most evident in troops who are not rotated and must remain exposed and in combat for prolonged periods of time. Three days of being cold and wet appears to be prudent timeframe within which to consider rotation of troops.
E. Racial susceptibility, blacks have a four to six times the incidence of cold injury than their white counterparts, matched for geographic origin, training and education. This increased susceptibility is related to:
1. Differences in anatomic configuration.
2. Differences in physiologic response to cold.
3. Once cold, blacks stay cold longer because of a less potent CIVD response to their
extremities. Place of origin has a significant role in cold injury susceptibility. Individuals raised in northern states have a more protective CIVD response. This response also improves in blacks from northern climates. Knowing what clothes to wear, knowing when one’s extremities are too cold, not being frightened of the cold, and knowing how to deal with cold extremities all add up to make cold-experienced individuals less likely to have cold injuries.
G. Psychological factors are involved with cold injuries with passive, negative individuals. Such individuals show less muscular activity in situation in which activity is unrestricted and are careless about precautionary measures when cold injury is a threat.
H. Other injuries are concomitant injuries that result in a reduction of circulation volume or localized reductions in blood flow predispose the individual to cold injury. Poor hydration and hypovolemia decreases perfusion of the extremities.
I. Drugs and medication may cause modifying autonomic nervous system responses, altering sensation or modifying judgement can have catastrophic effects on an individual’s performance and survival in the cold.
J. Hungry/malnourished causes inadequate calories for body metabolism and heat production cannot be maintained. Adequate hydration and food intake are important for prevention of cold injuries.
IV. Management is influenced by the tactical situation, the availability of evacuation to a fixed facility, and the fact that most cold injuries are encountered in large numbers, during periods of intense combat, and at the same time that many other wounded casualties are generated. Emergency treatment of cold injury is as follows:
A. All casualties with involvement of the lower extremities should be treated as litter cases if feasible.
C. All constricting items of clothing, such as boots, gloves, and socks, should be removed,
but only when adequate protection from further cold exposure is available. Boots and clothing frozen on the body should be thawed by immersion in warm water before removal. Vigorous manipulation of frozen parts or attempts at range of motion or massage should be avoided. If the hands are affected, rings should be removed from the finger early after presentation.
D. If the injured parts are still frozen when first seen and the risk of refreezing is very low, they should be rewarmed rapidly by immersion in water at 100-104o Fahrenheit with added antiseptic soap and with agitation of the bath water to hasten the warming. A whirlpool apparatus is most satisfactory for this. Refreezing of tissues greatly increases the amount of damage and lost tissue.
E. General body warmth must be maintained. Sleep and rest should be encouraged.
F. A booster dose of tetanus toxoid should be given to those previously immunized. No evidence exists that prophylactic use of antibiotics is valuable either in promoting healing or in preventing superficial or deep infection. In fact, the use of prophylactic antibiotics may result in the emergence of a resistant strain of organisms.
G. Large vesicles or bullae should be protected and kept intact if possible. Once ruptured, it is usually desirable to debride the vesicle. Ointment dressings have no place in the usual management of cold injury. Protective dry dressings are desirable during transportation, and sterile cotton should be used between the toes to prevent maceration.
H. Smoking is prohibited because healing tissues require maximum oxygen.
V. Later management:
A. Continued diligence to avoid further injury of already compromised tissue should be maintained. In general, for lower extremity injuries, this is accomplished by keeping the patient at bedrest, with the affected part elevated on surgically clean sheets under a foot cradle and with sterile pledgets of cotton separating the toes. Bearing weight on injured feet should not be allowed until mature epithelial tissue has developed over the affected areas. In upper extremities injuries, elevation is also desirable on sterile towels, with special care to bullae.
B. In an effort to reduce superficial bacterial contamination, the affected part is treated by whirlpool bath at 98.6o Fahrenheit (37o Celsius), with povidone iodine or hexachlorophine added, on a twice-daily basis, encouraging active motion on the part of the patient during the whirlpool treatment. Whirlpool baths assist in superficial debridement and make active range of motion exercises more tolerable to the patient and less traumatic to the tissues.
C. Analgesics may be required in the early post-thaw days, but a continued requirement for analgesics in uncomplicated injuries is uncommon.
D. The patient should be encouraged to consume a nutritious diet with adequate fluids to maintain hydration.
E. Patients should be place on surgical clean sheets and all lesions should be exposed to the air at normal room temperatures.
F. Superficial debridement of ruptured blebs should be performed, and suppurative eschars and partially detached nails should be removed. Close attention should be paid to circumferential eschars where vascular comprise could be a problem. Such eschars at least should be bivalved, although complete debridement is occasionally necessary. Early amputation has no place in the management of cold injury. Surgical intervention should be deferred until a distinct line of demarcation has developed.
VI. Prophylaxis.
A. Knowledge by command, staff, technical personnel, and all combat components regarding cold weather injuries, their prevention and their treatment.
B. Command supports for comprehensive and practical cold injury prevention and control program.
D. Clothing worn in loose layers, with air spaces between the layers, under an outer wind-
resistance garment. Body heat is thus conserved. Ensure garment, are flexible, and inner layers can be removed for comfort and efficiency in higher ambient temperatures or during strenuous physical exertion.
E. Special protection for certain groups who may be especially susceptible to cold injury,
together with the regular rotation of all troops.
F. Effective policies of sorting in forward areas, with provision for early evacuation and treatment of casualties actually suffering from cold trauma.
Followed by a drop into a subzero environment after their insulation clothing has been saturated with perspiration.
J. Ensure clothing is kept as clean as possible. Dirt within clothing fibers decreases available airspace and insulating value.
VII. Hypothermia.
A. Total body hypothermia is defined as a core temperature below 94o Fahrenheit (35o Celsius). Clinically, hypothermia may be classified as:
slow, as in exposure to more temperate environments. Trauma patients also are susceptible to hypothermia. Such hypothermia is preventable with the administration warmed intravenous fluids and maintenance of a warm environment. Since determination of the core temperature is essential for diagnosis, special thermometers capable of registering low temperatures are required. No one is cold and dead, only warm and dead. Failure to respond to rewarming is the only criterion for death in hypothermia.
1. Decreased core temperature.
2. An altered or depressed level of consciousness is the most common feature of
hypothermia.
3. Patient is cold to touch and appears gray and cyanotic.
4. All vital signs are variable (the absence of respiratory or cardiac activity in not uncommon):
a. Pulse rate.
b. Respiratory rate.
c. Blood pressure.
D. Field management of hypothermics (passive rewarming methods).
1. Immediate attention is devoted to the ABC’s, including the initiation of CPR.
2. Individuals must be stripped of their wet clothing.
3. Insulate with warm blankets. In a field environment you can place the patient with
another healthy individual in a sleeping bag, both with minimal clothing.
4. Establishment of warmed intravenous fluids (113o Fahrenheit or 45o Celsius).
5. Given warm, sweet drinks if conscious.
E. Active internal (core) rewarming methods for patients with profound hypothermia of long duration in which there is suspected underlying debilitation, for patients with complications of cardiovascular or respiratory insufficiency, and for patients in cardiac arrest.
1. Repeated peritoneal dialysis may be performed using warm (113o Fahrenheit or 45o Celsius) potassium-free dialysate solution. Two liters of solution should be exchanged at intervals of 10 minutes until the rectal temperature reaches 95o Fahrenheit or 35o Celsius.
2. Warm fluids (crystalloid solutions) administered by gastrointestinal, colonic or bladder lavage may be employed.
3. Administered of heated intravenous fluids may increase body temperature by less than 1/3 degree centigrade per liter. Microwave rewarming of crystalloid solutions to 104-107o Fahrenheit or 40-42o Celsius may be safely accomplished in about 2-3 minutes.
4. Heated humidified oxygen, 20 liters per minute contributes 30-40 kcal per hour.
Heat Injuries
I. Heat Syncope is simple fainting that occurs suddenly after exertion in the heat. Cutaneous and muscular vasodilation redistributes intravascular volume to the periphery of the body. Volume loss and prolonged standing (pool in the lower extremities) also contribute to the development of inadequate central venous return and insufficient cerebral perfusion. The patient’s skin is cool and moist, the pulse is weak, and there is transient hypotension. In general, core temperature is normal or mildly elevated.
II. Treatment:
III. Heat cramps are due primarily to electrolyte depletion and manifested by painful spasms of the voluntary muscles of the abdomen and extremities. The skin may be moist or dry, and cool or warm. Muscle fasciculations may be present. The core temperature is normal or only slightly elevated.
Salt tablets, "Gator Aid" or "Ten-K") with large amounts of water or ½ strength "Gator Ade" or any sport drink.
IV. Heat exhaustion is a systemic reaction to prolonged heat exposure (hours to days) and is due to sodium depletion, dehydration, accumulation of metabolites, or a combination of these factors. It is premonitory syndrome that rapidly evolves to heat stroke.
(usually when the water supply is inadequate); intense thirst and weakness occur, with marked central nervous system symptoms, including muscular incoordination, psychosis, delirium and coma. Hyperthermia may also occur.
2. Salt depletion occurs with those individuals that are not acclimatized to the heat and may develop symptoms as a result. This condition occurs when thermal sweating is replaced by an adequate intake of water but insufficient salt. Symptoms include muscle cramps, nausea and vomiting, diarrhea, weakness, pale skin, tachycardia and hypotension. Body temperature is usually normal or mildly elevated. Serum sodium levels are low, so replenishing water salt only aggravates the symptoms. The patient may not be thirsty and may not be sweating.
B. Measurement of serum electrolytes and renal function is advisable in most patients, since serum sodium concentration ma is a markedly low in-patient suffering from heat exhaustion. Myoglobinuria indicates subclinical rhabdomyolysis.
C. Treatment:
1. Position the heat patient in a cool place.
2. Give adequate cool 50% "Gator Ade" or any sport drink.
3. If patient is unable to drink fluids, give normal saline or Ringer’s Lactate.
V. Exertional heat injury is a syndrome that occurs in individuals who are exerting themselves in hot ambient temperatures (above 80o Fahrenheit) when the humidity is high. It is particularly common in runners who enter races with insufficient acclimatization, inadequate conditioning or improper hydration (before and during the race). Obesity, age and previous heat stroke are contributing predisposing factors. In contrast to classic heat stroke, individuals with exertional heat injury usually sweat freely and their temperatures are lower (102o Fahrenheit to 104o Fahrenheit as opposed to 106o Fahrenheit and higher in heat stroke).
A. Symptoms consist of headache, piloerection (gooseflesh) on the chest and upper arms, chills, over-breathing, nausea, vomiting, muscle cramps, ataxia, unsteady gait and incoherent speech. In some individuals, loss of consciousness occurs.
B. Physical examination shows tachycardia, hypotension and evidence of low peripheral resistance.
C. Diagnosis consists of laboratory data showing hemoconcentration, hypernatremia, abnormal liver and muscle enzymes, hypocalcemia, hypophosphatemia, and in some instances hypoglycemia. An occasional patient has thrombocytopenia, hemolysis, disseminated intravascular coagulation, rhabdomyolysis, myoglobinuria and acute tubular necrosis.
1. Placing the victim under wet cold sheets to quickly lower core temperature to 38o
Celsius.
2. Massaging the extremities to improve blood flow from the core to the periphery.
3. Infusing fluids consisting primarily of hypotonic glucose-saline.
4. Patients should be observed closely or hospitalized for 36 hours after injury.
VI. Heat stroke is characterized by dysfunction of the heat-regulating mechanism, with altered mental status (ranging from confusion to coma) and elevated core body temperature in excess of 105.8o Fahrenheit or 41o Celsius. Sweating may be variable. The extremely high body temperature rapidly causes widespread damage to body tissues, with significant rhabdomyolysis. Illness and death result from destruction of cerebral, cardiovascular, hepatic and renal tissue. Heat stroke usually follows excessive exposure to heat or strenuous physical activity under exceptionally hot environmental conditions.
1. The skin is hot, flushed, and usually dry (although sweating may be present)
metabolic acidosis.
(SGOT).
1. Act quickly to prevent further injury.
2. Give supplemental oxygen at 6-10 liter per minute by mask or nasal prongs.
3. Reduce body temperature promptly:
a. Place the patient in a shady, cool place, and remove clothing.
b. Sprinkle the patient’s entire body with water and cool by fanning.
c. If the victim is near a cold stream, cautiously immerse the trunk in cool water.
d. Place ice packs on the axilla, posterior neck and inguinal areas.
5. When the rectal temperature drops to 100.4o Fahrenheit or 38o Celsius, discontinue
active measures to lower temperature but continue temperature monitoring.
6. Chlorpromazine, 10-25 mg given slowly intravenously, may be used to control shivering.
7. Maintain adequate urinary output at 30-50 ml per hour.
8. Hospitalize all patients whose core temperature has exceeded 105.8o Fahrenheit or 41o Celsius.
9. Consider core-cooling technique such as bladder irrigation and nasal gastric tube irrigation with ice water or peritoneal lavage with ice water.

Footcare
I. Basic Footcare:
A. Washing and drying feet daily if possible.
B. To keep feet dry, spray the feet with the silver can of "Rightguard" or a similar
Aluminumchlorhydrate antiperspirant. Do this two or three times per day for a week and then once a day for the rest of the winter. If fissure or cracks occur on the feet, discontinue until healed and then use less frequently to control sweating. This process will stop approximately 70% of the sweating in your feet.
C. Daily massaging your feet, especially after marching. Use talc or antifungal powder everyday.
D. Keep nails trimmed but not too short. Long nails wear out socks; short nails do not provide proper support for the ends of the toes. Trim nails straight across to prevent ingrown nails.
E. Care of blisters is accomplished by cleaning with betadine, let dry for min; release fluid from the side of the blister with a clean, sterile needle, gently press out the fluid leaving the surface intact. Make doughnut of moleskin to go around the blister and apply to intact skin. Wrap entire toe or only over the top of the moleskin with a loose wrap of adhesive tape.
II. Socks provide a variety of protections by:
III. Leather care for boots. The old style combat boot is best waterproofed with oils and waxes. This should be done routinely to re-established water repellency. Seams and welt are the most important points to cover. The speedlace combat boot has silicone treated leather and must be water proofed only with silicone material. Siliconized leather retains its water vapor permeability and breathability while being highly waterproof. Use of oils and waxes on these boots will destroy the ability to remain breathable, waterproof and compromise the ability to siliconize the leather itself. Silicone leather does not take a high shine.
IV. Fitting of boots:
D. Stand on the shoe sizing device and lean slightly forward with some weight on the ball of
your foot.
E. Measure the length and width of each foot 2-3 times to assure you have the proper size information. Your foot will lengthen and widen under the load. This will allow you a large enough boot to accommodate the proper socks and the change in your foot size while you march.
V. Marching- if you feel any slight compression or abrasions on your feet, stop and apply tape or moleskin to the area. Do not wait until you have a blister to take care of your feet.
VI. Cold weather protection:
marching with loads is not necessary. Heavy marching with VB boots will produce blisters. The foot becomes damp and skin softens inside the VB boot. Great care is necessary to prevent blisters while walking in this boot.
E. There is a wide range of temperatures at which different individuals will require VB
protection.
F. The greatest heat loss from the foot occurs through the sole and the toecap. You must
insulate your foot from the soles of the leather boot with insoles, and there must be enough volume in the toecap to allow for thick socks and air space around the toes. This requires a larger inside volume of the boot than what most soldiers wear daily.
G. Remove boots, massage feet and change socks at least daily (more frequently if the socks become wet).
Field Sanitation
I. Purpose:
A. To establish measures which must be routinely performed and habitually practiced to ensure proper health of troops under all conditions.
B. This Standard Operating Procedure (SOP) specifies for all FTX’s and contingencies the:
1. Required field sanitation supplies and equipment.
2. Routine, special and emergency sanitation measures to be utilized.
II. Responsibilities of a Field Sanitation Team (FST) during mobilization, the FST performs sanitary duties specified by the unit’s SOP. Duties include inspection of water containers and trailers, disinfecting of unit water supplies, check of unit water supply for chlorine residual, inspection of unit field food operations, control of insects in the AO, supervise construction of field sanitation devices and garbage pits, provide training and advise commanders on all field sanitation matters.
A. A field sanitation team will be designated by each company commander, it will consist of one NCO and one enlisted.
B. The senior line medic for each line company is overall supervisor and field sanitation authority.
C. Field sanitation team responsibilities:
1. Conduct training within the unit on proper field sanitation, including heat/cold injury prevention classes.
2. Inspect water containers and trailers daily.
3. Disinfect unit water supplies.
4. Water sanitation:
a. All unit water must be obtained from approved sources.
5. Survey for rodent problems.
6. Field food sanitation, the five factors most often involved in outbreaks of diarrhea
caused by contaminated food are:
a. Failure to keep potentially hazardous food cold (below 45 degrees Fahrenheit).
b. Failure to keep potentially hazardous food hot (above 140 degrees Fahrenheit).
c. Allowing potentially hazardous food to remain at warm temperatures.
7. Apply pesticide as needed.
8. Monitor construction of all field waste disposal operations.
a. Garbage- during FTX’s all trash will be brought back to garrison and disposed of in dumpsters. All recyclable cardboard is to be maintained separate from the remainder of the trash and taken to the recycle point. Ensure that unused MRE heaters and unfired ammunition or explosives are not mixed with the trash that is destined for disposal at a landfill. In a wartime situation, the method of garbage disposal is based on the tactical situation. The most common forms are:
1) Burial. Do not bury within 100 ft. (30 meters) of any water source. The burial area should be a reasonable distance from the kitchen to minimize problems with flies and appearance. On the march, in bivouac, or in camps of less than 1-week duration, waste is disposed of in burial pits or trenches.
2) Pits are preferred for overnight halts and are usually dug four foot square and four foot deep (see figure A-22 on page 78).
3) Trenches are adapted for stays of two or more days. This method is started by digging a trench two foot wide, four foot deep and longs enough to accommodate the garbage.
4) Incineration in temporary camps of one week or more, the garbage is often burned at least 50 yards (50 meters) downwind from camp (see figure A-23 on page 80 and figure A-29 on page 81).
b. Liquid kitchen wastes accumulate at the rate of one to five gallons per soldier per day.
1) Soakage pits are constructed in the same manner as a soakage pit for urine disposal except it is equipped with grease trap (see figure A-24 on page 80).
2) Filter grease traps are made using an oil drum with its top removed. The bottom is perforated and filled 2/3 full with crushed rocks or large gravel at the bottom, followed by charcoal or straw. Cover the top with burlap or other fabric to strain out the larger waste pieces. Place it in the center of a soakage pit with the bottom of the barrel two inches below the pit surface. Close all latrines and garbage pits when filled to within one foot of the ground surface. Close out by packing earth in successive three-inch layers until mounded one foot above ground level. Post a sign stating "CLOSED LATRINE/GARBAGE PIT" with date (except in combat).
9. Human waste disposal units are to coordinate for chemical portable latrines whenever a battalion size or larger unit continuously occupies a high use bivouac area for more than 72 hours (where a concrete pit latrine is not available). These latrines need to be within 10 feet of a gravel road. They also need to be filled with five gallons of water before first using. If field latrines must be used:
a. Locate latrines at least 100 yards (90 meters) downwind from any unit food service facility and 100 feet (30 meters) from any ground water source.
b. There should be enough field latrines for four percent of the males and six percent of females (see figure A-12, A-13, A-17, A-18 and A-19 on pages 75-78).
c. Attempt to locate the field latrines 30 yards (30 meters) from the border of the unit area, but within a reasonable distance.
d. When the field latrine is filled to within one foot of the ground surface, have it closed (see figure A-16 on page 76). Contact range control when it is closed.
e. Ensure there is a hand washing device outside any latrine (see figure A-2 and figure A-3 on page 74).
10. Conduct inspections in proper field hygiene and sanitation practices.
11. Ensure the prevention of heat and cold injuries.
D. The FST is overall responsible to stock the companies chests. All companies will deploy to the field with their internal preventive medicine chests.

The treatment site must be able to support the tactical operations at all times.1. When battle lines are fluid and air evacuation difficult or impossible, medical officers must be placed where they can receive, triage, resuscitate and evacuate casualties emerging from the battle zone.
2. If air evacuation capability exists, aircraft to the battle site to provide on-site triage may dispatch the medical officer.
3. If distances to surgical care are great and air evacuation is not possible; the medical officer may request a forward surgical team to augment the medical element and to perform their resuscitative surgical procedures.
C. Factors needed by the medical element:
1. Cover, concealment and security.
2. Site must be large enough to accommodate organic vehicles and a triage area.
3. Hardstand drainage (high ground with good drainage).

5. A MEDEVAC LZ within 100-150 meters of the triage site.
6. Site must be within routes of patient flow.
7. Be at least one key terrain feature from the forward edge of the battle area (FEBA).
8. Near support and supporting units.
III. Operations:
A. The medical element does not necessarily require shelter unless weather or night operation light discipline mandates concealment and shelter.
B. The medical element should be considered an area rather than a facility. The casualty collection point (CCP) should be co-located with the medical element.
C. After an appropriate site is chosen, it must be further divided into functional areas:
1. Triage.
2. Immediate treatment.
3. Delayed/minimal.
4. Expectant casualties.
5. Casualty flow in a linear manner (one directional flow).
6. Provide 24 hour continuous medical support.
7. Keep an accurate admissions and dispositions (A & D) log of all patients. Keep the J1 informed of status.
