A. If you have an unconscious victim, you should not move them unless they are in immediate danger from fire, etc.

B. You should first attempt to arouse an apparently unconscious victim..

C. If you have an accident, or a victim of an accident, you should immediately perform a quick physical examination to determine the extent and seriousness of all injuries. Start at the top and work down. Examine both the front and back. Move the victim as little as possible. Check the pulse, observe the breathing, check for bleeding, breaks, etc.

D. The life saving steps are those steps taken to stabilize a victim until medical rectumistance can be obtained. They include:

(1) Clearing the airway.

(2) Restoring the breathing.

(3) Restoring the heartbeat

(4) Controlling the bleeding.

(5) Protecting the wound.

(6) Treat/prevent shock.

E. Burns are very painful and can cause scarring or death. Expose the burned area without pulling clothing over the burn or removing clothing stuck to the burn. Apply a loose, dry sterile dressing over the burn. Do not apply ointment or grease. Do not break blisters. Treat for shock. Prevent infection. Give small amounts of water if not nauseated and no neck or abdominal wound is evident. Give aspirin to relieve the pain. For serious burns, treat for shock and evacuate if possible.

F. Sprains and strains are common occurrences in the outdoors. Initially, treat sprains and strains with cold to prevent swelling. Wrap affected area tightly but do not cut off circulation. Give aspirin to relieve the pain and reduce the swelling. Treat with heat to ease pain and promote healing.

G. The rule for breaks is to "splint them where they lie." Immobilize the fracture without changing the position of the fracture and before moving the victim. Immobilize the joint above and below the break. Pad the splints and use nonslip knots. Treat the wounds caused by compound (open) fractures as you would any open wound. Remove watches, rings, or any binding object from the extremity to be splinted to prevent trauma caused by swelling. Give aspirin to relieve the pain and reduce the swelling. Treat for shock and evacuate if possible.

H. Snake bites are very serious and require immediate attention to prevent possible death. Remain calm. Immobilize the affected part below the level of the heart. Place a constricting band two to four inches above the wound, between the wound and the heart. Remove any articles (watch, ring, etc.) that may bind during swelling. Move the constricting band ahead of the swelling. Cool the area to slow the venom and swelling if possible. Do not give stimulants (coffee, tea, alcohol, tobacco, etc.) and do not cut the wound or suck the venom. Give aspirin to relieve the pain and reduce the swelling. Treat for shock and evacuate if possible.

I. Insect and animal bites should be cleaned to prevent infection, cooled to prevent swelling, and covered. If swelling is present, remove binding articles. Give aspirin to relieve the pain and reduce the swelling. Evacuate if possible.

J. Heat injuries include heat cramps, heat exhaustion, and heat stroke.

(1) For heat cramps and exhaustion, move victim to shade, loosen clothing, force victim to drink three to five quarts of water (salted if possible-one quarter teaspoon per quart) slowly over an 8-12 hour period.

(2) For heat stroke, immerse the casualty in the coolest water available. If limited amounts of water are available, strip the casualty, pour water on him, and fan him continuously. If the casualty is conscious, give him cool water. Evacuate immediately.

K. Cold Injuries include chilblain, hypothermia, immersion syndrome, frostbite, snow blindness, and dehydration.

L. (1) The treatment for hypothermia is the slow, even rewarming of the body. In a survival situation, strip and dry the casualty and place in a sleeping bag or bundle in blankets. Another naked person may be placed in the bag to add body heat. Warm liquids may be given slowly but should not be forced to an unconscious person.

(2) Frostbite should be treated immediately by increasing circulation (do not massage, rub with snow, manipulate, heat with open heat source, apply ointment, etc.) and increasing insulation. Do not expose a frostbitten location to the cold once it has thawed.

(3) Dehydration should be treated by warming the casualty and loosening the clothes. Minerals and fluids should be replaced slowly and as soon as possible (see heat injuries).

L. Prevention is the key to avoiding problems in a survival situation. If you don't become injured or sick, you won't need to use these techniques. The key to remaining healthy in a survival situation depends on four factors: adequate food and water, good personal hygiene, sufficient rest, and shots and immunizations being up to date. Prevention of infection is considered the primary goal of staying healthy in a survival environment.

M. Survival medicine should be considered as a last resort when no other medical option exists for the treatment of disease, wounds, or injuries. The most common areas of survival medicine deal with the treatment or symptomatic treatment of wounds, skin infection, diarrhea, intestinal parasites, and burns.

(1) The treatment of open wounds in a survival environment is critical due to the loss of blood and tissue as well as the possibility of infection. Open wound therapy is the treatment of choice in a survival situation. Clean the wound as soon as possible after it occurs. Remove clothing from the area of the wound, clean the skin around the wound, and rinse (DO NOT SCRUB) the wound with large quantities of the cleanest water available (sterile or boiled water, sea water or a saline solution made of one teaspoon salt or 12 salt tablets per liter of sterile water; fresh male urine ["straight from the spigot"] will suffice if water is in short supply and donor has no diseases). Leave the wound open to allow pus and infectious material to drain. Cover the wound with a clean dressing and bandage. Change the dressing daily and check the wound for infection. Pain, swelling, redness, increased temperature, and pus are indications of infection. If infection is present, place a warm, moist compress directly on the wound. Change the compress as it cools and maintain the compresses for 30 minutes, three to four times daily. Open the wound and drain the infected material. Use a sterile instrument (knife, piece of glass, etc.) to rectumist in the removal of all pus and crusted matter. Redress the wound, drink lots of fluid, and continue the treatment until all signs of infection are gone. If the wound is severely infected and cannot be controlled, consider the "Maggot Therapy" for treatment. This should only be considered if antibiotics are unavailable and the infection is not responding to other treatment. Expose the open wound to flies for one day, cover the wound, and check for maggots daily. Once maggots appear, keep the wound covered but check it daily. Remove all maggots and rinse the wound with large quantities of sterile water once they reach healthy tissue (increased blood, pain, and redness will result). Check the wound every four hours for several days to insure the maggots are gone. Repeat steps as necessary should the infection return or maggots reappear. Dress the wound and treat as any other open wound once the treatment is over.

(2) Skin infections such as boils, funguses, and rashes seldom become major problems but are annoying. Apply warm compresses to a boil and bring it to a head. Open the boil with a sterile object and clean out the pus and matter. Clean with soap and water and treat as a minor wound, check for infection periodically. For fungal infections and rashes, keep the area as dry and clean as possible. Expose fungus infections to as much sunlight as possible. A cold compress will relieve the itching of some rashes.

(3) Intestinal parasites are always a possibility in a survival environment. Proper hygiene and food preparation minimize the possibility of infestation. Treatments are acts that change the environment of the intestinal tract and allow the parasites to be passed. Mix four tablespoons of salt with a quart of water and drink it. Do not repeat this treatment. Eat one to one and one-half cigarettes. You may repeat this treatment in 48 hours. Drink two tablespoons of kerosene. This treatment may be repeated in 48 hours. A steady diet containing hot peppers is also effective.

(4) Diarrhea is a very serious, sometimes fatal, debilitating symptom of several diseases. It generally kills through dehydration. It should be treated promptly so as to minimize the effects. Limit your food and fluid intake for 24 hours and drink one cup of strong tea every two hours until the diarrhea slows or stops (tea contains tannic acid which is effective against diarrhea). If tea is unavailable, boiling acorns or the inner bark of hardwood trees will produce a solution that contains tannic acid. One handful of ground chalk, charcoal, or bone, mixed in a cupful of water is also effective. Add an equal portion of apple pomace (the pulpy material that remains after the juice has been squeezed out), or chopped citrus fruit rinds to the solution. Take two tablespoons of this primitive "kaopectate" every two hours until the diarrhea slows or stops. Drink lots of purified water and limit foods to bland, starchy dishes or clear broths once the diarrhea is under control.

(5) Burns in a survival situation are critical because of the pain, dehydration, and probability of infection that accompanies the destruction of tissue. Never apply grease, fats, or ointments. Remove all clothing and jewelry from the burned area that may cut off circulation during swelling. Always cut clothing away--do not pull over injured area. Cool water, applied immediately, will minimize tissue damage. Apply dressing or clean rags that have been soaked for ten minutes in a boiling tannic acid (tea, acorns, or inner bark of hardwood tree) solution and allowed to cool. Cover the burn with loose clean dressings and give aspirin to relieve the pain. Administer approximately 1 quart of water per 8 hour period to prevent dehydration. If
available, add 1/2 teaspoon of salt and 1/2 teaspoon sodium bicarbonate (baking soda) per quart of water. Use salt alone if no sodium bicarbinate is available.

(6) There are many primitive or herbal medicines in use worldwide. Wild garlic and onion have low grade antibiotic qualities when eaten. "Jewel-weed" will sooth the itch of poison ivy, etc. The inner bark of the willow tree contains a salicylic acid (aspirin) like compound for the reduction of fever, swelling, and pain. Pine needle tea is an excellent source of Vitamin A. The local inhabitants of an area are excellent sources of this type of knowledge. You should only use these herbal remedies when no other medical supplies are available.

A) and you move an unconscious pt how? - what about extraction?

B) ...arouse unconscious pt... interesting choice of words ;-) well a humans eroginous zones are best stimulated by light carress of the fingers or the tounge and... :smile: but on a serious note, light to med tapping or shaking on the sholder as well as talking to the pt loudly to try to get a responce should be your first try, after that attempt to get a pain responce - pinching ear lobes or pressing a fingernail directly under their fingernail on the end of the finger is effective.

C) PE - we were trained to do a quick primary evaluation: ABC (Airway, Breathing Circulation). If there is a problem in one of these areas take care of it, THEN do a through evaluation. ABC has some considerations they don't tell you about in the basic first aid cources. First is cervical spine injuries: If the pt is not breathing, the Red Cross tells you to tilt the head back, pinch the nose and start giving breaths. Slight problem: if there is a crevical injury above C3(?) there is a good chance of severing the vagus (10th cranial) nerve. This sends nerve impulses to the heart and lungs, allowing them to function. Above C6(?) and you've turned your pt into a paraplegic. Alternative methods of airway management should be considered if this is the case. Your average head weighs 8-10 pounds (about what a bolling ball does) and will obey gravity if not supported - this is an important consideration if attempting to move an unconcious pt. Idealy, one person should be there to support the head, Use of a C-collar or backboard is advised, if at all possible. Towels, a pair of pants, etc, and tape can be used to improvise a C-collar. It should be firm enough to support the head, but not so tight as to obstruct air or blood flow.

Obstructed airways from things lodged in the throat have been traditionally cleared by back blows and the Heimlich manuver. Back blows have fallen out of favor as they occasionally force the obstruction farther into the throat. Abdominal thrusts are commonly taught incorrectly. Standing behind the pt, the rescuer forms their hand into a fist and places it just below the sternum, the other hand goes arround the body the other way and surrounds the fist. At this point, your arms are in a "O" type shape arround the patient, and this is how it's commonly illustrated and taught. This is wrong. Your arms should be in an "M" with the elbows sticking out. Why? because of the floating ribs. Take a particularly strong, or just excited and scared rescuer, and they can apply a lot of force in performing this manuver. If the floating ribs break, they will naturally go inward. What's under the floating ribs? kidneys. Ruptured kidneys equil dead patient. It happens!

Circulation: everyone should know CPR. If you have an older pt, anticipate flail chest and be ready to tape the ribs. On bleeding: pt's can completly bleed out internally, generally into the abdominal cavity or sometimes into a thigh, and not have any visible blood outside the body. If so, realize what's happening and scoop and run. If it's into the thigh, apply a tourniquet. On tourniquets: you are generally trading a life for a limb, if you apply one. This is a method of LAST resort! Try applying firm pressure first! If you have to apply one, *NEVER* use rope, cord, etc. Allways use the widest thing you can get your hands on (this maximises the chances of saving the limb), and belts or elastic bandages applied tightly, work well. Tourniquetes are especially dangerous in an extended care situation, as gangreen(sp?) will set in if you don't amputate.

More on bleeding: blood is very dramatic. It spreads well on hard surfaces, giving the illusion that more blood has been lost than is the case. On pourous surfaces like dry sand or soil it can be absorbed and leave a deceptively small "puddle", leading you to believe that there wasn't that mutch blood loss. Keep these things in mind. If you apply trama pads "blood sopper uppers", and maxi-pads are cheap and work really well for this, they will become soaked. *DON'T* remove them and put a fresh one on there!, Instead slap another one on top. Why? Dr's are quite good at estimating blood loss from looking at soaked bandages, and this is necessary to know for fluid replacement. In an extended care situation, getting under them and doing that estimation will be your job. In addition, any clotting that is going on will be disturbed, every time you change dressings. A good training exercise it to take some water and food coloring and pour, say 1/4 cup of this onto various surfaces in order to learn how to estimate blood loss. I have never seen a chart compairing puddle size or BP to blood loss, but I'm sure one exists.

The ABC's are there for one purpose - to supply blood to the brain. If the brain doesn't get oxygenated blood, it dies, causing the body to die. Children are more resistant to oxygen starvation than adults are. People that are extreamly cold, for example, suffering from hypothermia as a result of cold water immersion, will also be able to tollerate oxygen starvation better. In such situations, resusitation attempts should be made even if the person hasn't been breathing for some time.

Shock is secondary to other injuries. Well, there are different types of shock, but good old generic shock is generally because there isn't enough blood flowing to oxygenate the brain. If you come upon a scene where you have some loud mouth screaming their head off and others that are quiet, ignore the loud mouth - they are doing fine. The quiet ones are the ones you should be worried about. If you find a quiet child that has suffered trama, be scared, be *VERY* scared!
The common Tx for shock is to have the pt lie down and elevate their legs. This uses gravity to force more blood into the torso and head, providing oxygenated blood to the vital organs and the brain. The military developed something called MAST trowsers, I'm not sure if they are still SOP, but they are inflated, applying pressure to the legs and forcing more blood into the torso. They are expensive and bulky. The S&R community developed the "poor mans MAST trousers", they are cheap, light weight and not very bulky. They are alsoknown as elastic bandages - just carry more of them than you normally would. start by elevating the extremity, and then apply from the ankle or wrist in a spiral fashion toward the trunk. You get much more of an advantage from doing the legs, than arms. They should be tight, but still allow blood flow. If there is an injury that you anticipate will swell, do not apply them to that area. Doing so will create a tourniquet, when swelling does occur. If you are establishing a "lifeline" (an IV to administer drugs or for fluid replacement), do not do this to that limb.

If you've taken the Red Cross Standard First aid cource, they taught you all sorts of things about applying pretty bandages. If you are dealing with trama, *FORGET* everything you learned in that class about bandaging. IT IS INEXCUSABLE TO DELIVER A WELL PACKAGED PATIENT, DEAD!!!!

Remember: "First I will do no harm!", well meaning rescuers kill the people they are trying to rescue, every day, because they didn't know any better.

that's all I can think of right now. Hope it helps.

M2) If it's dry wet it, if it's wet dry it.

additional note on trama - there is soemthing known as the "golden hour", if your pt has suffered serious trama, their chances of living increase exponentially if you can get them into the hands of ALS (Advanced Life Support) within 60 minutes of that trama happening. Being able to evacuate a pt or get help to come to a pt in that time frame can mean the difference between life and death. Radio's and cell phones are an often neglected part of a good medical kit. If you are in a survival or disaster situation, you are that ALS. Unfortunatly, even with the supplies and training, you will be severly limited in what you can do. Many ALS techniques that are within reach have the potential to kill the patient if done wrong. It's often better to try and stabalize the pt and hope for the best.
