Sorting for Tactical Treatment
Class I walking wounded
Class II injuries require immediate life sustaining measures. Initially require minimum amount of time.
Class III Definative treatment can be dleayed without jeopardy to life or loss of limb
Class IV Expectant
Sorting for Nontactical treatment
Priority I life threatening injuries
Priority II serious but not life threatening injuries such as moderate blood loss, open or multiple fractures
Priority III walking wounded
Priority IV dead or fatally injured
Primary Survey
Treat as you go. A rapid initial assessment to detect and treat life threatening conditions that require immediate care. Concerned with ABCDEs.
Airway
Breathing
Circulation
Disability
Expose
As soon as ABCDE process is completed, you will need to make a status decision of the patient's condition.
What is a status condition?
A judgement call about the severity of the patient's condition and wether the patient requires immediate transport to a medical facility without a secondary survey at the scene.
Secondary Survey
Head to toe exam. Complete and detailed exam consisting of a subjective interview and objective exam including vitals.
Signs and symptoms of shock
- Restlessness and apprehension are early symptoms, often followed by apathy.
- Eyes may be glassy and dull. Pupils may be dilated. (These are also the symptoms of morphine use.)
- Breathing may be rapid or labored, often of the gasping, for air hunger, type. In the advanced stages of shock, breathing becomes shallow and irregular.
- The face and skin may be very pale or ashen gray; in the dark complexioned, the mucous membranes may be pale. The lips are often cyanotic.
- The skin feels cool and is covered with clammy sweat. The skins coolness is related to a decrease in the peripheral circulation.
- The pulse tends to become rapid, weak, and thready. If the blood pressure is severely lowered, the peripheral pulse may be absent. The pulse rate in hemorrhagic shock may reach 140 or higher. In neurogenic shock, however, the pulse rate is slowed, often below 60.
- The blood pressure is usually lowered in moderately severe shock; the systolic pressure drops below 100, while the pulse rises above 100. The body is compensating for circulatory fluid loss by peripheral vasoconstriction. This process tends to maintain the blood pressure at a nearly normal level despite a moderately severe loss of circulating blood volume. A point comes, however, when decompensation occurs, and a small amount of additional blood loss will produce a sudden, alarming fall in blood pressure.
- There may be nausea, vomiting, and dryness of the mouth, lips, and tongue.
- Surface veins may collapse.
- There are frequent complaints of thirst.
- The kidneys may shut down. Urine formation either ceases or greatly diminishes if the systolic blood pressure falls below 80 for long periods of time.
- The person may faint from inadequate venous blood return to the heart. This may be the result of a temporary gravitational pooling of the blood associated with standing up too quickly.
How to control hemorrhage
Pressure dressing - the best way to control external bleeding is by applying a compress and exerting pressure directly to the wound.
Pressure points - the spot where the main artery to an injured part lies near the skin surface and over a bone. There are 11 principle points on each side of the body, 22 total. It can seldom be maintained for more that 15 min.
Tourniquets - used only as a last resort. Use any long flat material. do not use rope, wire, string or very narrow pieces of cloth because they cut into the flesh. Removed only by doctors.
Head wounds
Never give any medications
Keep victum lying flat with head at level of the body. Do not raise the feet if face is flushed.
If wound is in the back of head, turn patient on his side.
Do not use direct pressure to control hemorrhage if the skull is depressed or obviously fractured.
Facial wounds
Apply sterile compress and hold it in place with a firm bandage.
Chest wounds
Most serious injury that requires immediate attention is a sucking chest wound. Victims with open chest wounds gasp for breath, have difficulty breathing out and may have a bluish skin color to their face. Frothy-looking blood may bubble from the wound during breathing. Immediately seal the wound with any airtight material available. If patients condition suddenly deteriorates when you apply the seal, remove it immediately. Place patient in Fowler's or semi-Fowlers position. During combat, lay patient on stretcher o the affected side. Do not give anything to drink.
Abdominal wound
Do not attempt to push the intestines back in or to manipulate them in anyway. If bleeding is severe, try to stop it by applying direct pressure. If intestines are exposed, apply a sterile compress moistened with sterile water. Do not give anything to drink.
Open fracture
Open wound in the tissues and skin. Can be caused by the sharp end of a broken bone pushing through the flesh or by an object penetrating form the outside.
Closed fracture
Injury is internal, there is a break in the bone but not the skin
Upper arm fracture
Do not attempt to straighten or move it in any way. Spint in the position you find it in.
Forearm fracture
When the radius and ulna are both broke, the ar usually appears to be deformed. When only one bone is broke the other acts as a splint. Apply 2 well padded splints to the forearm, one on top and one on bottom. Put the forearm across the chest, palm turned in, with thumb pointing upward. Hand should be raised 4 inches above the elbow.
Lower leg fracture
Apply three splints, one on each side of the leg and one underneath.
Thigh Fracture
Femur fracture, limb is usually assumes an unnatural position, with the toes pointing outward. Fractured leg is shorted than the other. Apply 2 splints. One outside the injured leg from the armpit to the foot and one on the inside from the crotch to the foot. Fasten in 5 places, around ankle, over knee, just below hip, around pelvis and below armpit.
Clavicle fracture
When the patient stands, the injured shoulder is lower than the uninjured one. Figure of eight bandage may be used.
Rib fracture
Swathe arm on affected side to chest. Do not apply adhesive directly to skin for immobilization.
Burns
The seriousness of the injurt can be estimated by depth, extent, and location, the age and health of patient and other medical complications.
First degree burns
Involves epidermial layer that becomes irritated, reddened and tingling. Healing usually occurs naturally within a week.
Second degree burns
Epidermal blisters, mottled appearance, and a red base. Damage extends into but not through dermis. Recovery usually takes 2 to 3 weeks. Weeping fluid loss at surface.
Third degree burns
A full thickness injury penetrating into muscle and fatty connective tissues or even down to the bone. Tissue color will range from white (scalds) to black (charring).
First aid for burns
Maintain open airway
Remove constricting jewelry and articles of clothing
Cover with clean sheets
Do not remove clothing adhering to skin
For all serious burns over 20 percent BSA and in the presence of shock start IV therapy eith LR in an unburned area
Relieve mild pain with aspirn. Moderate pain with cool, wet compresses or ice water immersion (for burns less than 20% BSA) Severe pain may be relieved with morphine or demerol injections.
Aid station care of burns
Give a booster dose of tetanus to all major burn patients.
Apply 1/16 inch thickness of Sulfamylon or Silvadene.
Heat cramps
Excessive sweating may result in painful cramps in the muscle of the abdomen, legs, and arms. May also result from drinking ice water or other cold drinks either too quickly or in too large a quantity after exercise. Move the patient to a cool place. Caused by a loss of salt and water, give plenty of cool water, adding one teaspoon of salt to a liter or quart. Apply manual pressure to cramped muscle, or gently massage to relieve spasm.
Heat exhaustion
Most common condition caused by working or exercising in a hot environment. The vital signs usually are normal; however, the victim may have a weak pulse, together with rapid and shallow breathing. Body temperature may be below normal. Treat heat exhaustion as if the victim were in shock. Move the victim to a cool or air-conditioned area. Loosen the clothing, apply cool wet cloths to the head, axilla, groin, and ankles, and fan the victim. Do not allow the victim to become chilled. If the victim is conscious, give a solution of 1 teaspoon of salt dissolved in a liter of cool water. Intravenous fluid infusion may be necessary for effective fluid and electrolyte replacement to combat shock.
Heat stroke
Carries a 20% mortality rate. Most important feature is extremely high body temp 105 degrees F/41 degrees C or higher. Immerse in cold water bath. Do not give hot drinks or stimulants. Discontinue cooling when temp reaches 102 degrees F. Repeat cooling if temp reaches 103 degees F rectally.
Hypothermia
First sign is shivering.
Replace wet or frozen clothing and remove anything that constricts arems, legs, fingers or interfering with circulation.
Immersion in tub of warm water 100 to 105 degree F.
Buddy warming
Give warm liquids, never give alcoholic beverages or allow pt to smoke.
Immersion foot
Prolonged exposure to to wet cold at temp ranging from jusr above freezing to 5 degrees F. Swelling of the legs, feet, or hands, bluish discoloration of skin, painful blisters, Gangrene may occur.
Remove wet shoes, socks. and gloves to imorve circulation.
Do not rupture blisters or apply salves and ointments.
Frostbite
Exposure to temps of 32degrees or lower.
Superficial Frostbite
Surface of skin will feel hard, but the underlying tissue will be soft, allowing it to mive over bony ridges.
Rewarm habds by placing them under the armpits, against the abdomen or between the legs.
Deep Frostbite
Freezing reaches into the deep tissue layers. Ice crystals in the entire thickness of extremity. Skin will not move over bony ridges ans will feel hard and solid.
Do not attempt to thaw area if there is a possibility of refreezing.
Treat all pts with injuries to the feet and legs as litter pts.
Rapidly rewarm by immersion in water at 100 to 105 degrees F.
