Liquids should be administered sparingly, and not at all if medical attention will be available withina short time. If necessary, small amounts of warm water, tea, or coffee may be given to a victim who isconscious. Persons having serious burns are an exception. Burn victims require large amounts of fluids.Water, tea, fruit juices, and sugar water may be given freely to a victim who is conscious, able toswallow, and has no internal injuries. Slightly salted water is also beneficial. Alcohol must never be givento a person in shock.An injured person may or may not be in pain. The amount of pain felt depends in part on the person'sphysical condition and the type of injury. Extreme pain, if not relieved, can increase the degree of shock.Make the victim as comfortable as possible. Fractures should be immobilized and supported.Immobilization greatly reduces, and sometimes eliminates, pain. Normally, you should not administerdrugs, but aspirin may be given for mild pain.Heat is important in the treatment of shock to the extent that the injured person's body heat must beconserved. Exposure to cold, with resulting loss of body heat, can cause shock to develop or to becomeworse. You will have to judge the amount of covering to use by considering the weather and the generalcircumstances of the accident. Often a light covering will be enough to keep the casualty comfortable.Wet clothing should be removed and dry covering provided, even on a hot day. Use blankets or any drymaterial to conserve body heat. Artificial means of warming (hot water bottles, heated bricks, heatedsand) should not ordinarily be used. Artificial heat may cause loss of body fluids (by sweating) and itbrings the blood closer to the surface, thus defeating the body's own efforts to supply blood to the vitalorgans and to the brain. Also, the warming agent may burn the victim.BurnsThe seriousness of a burn depends on two factors: the extent of the burned area and the depth of theburn. Shock can be expected from burns involving 15 percent or more of the body. Burns involving 20percent endanger life. Without adequate treatment, burns of over 30 percent are usually fatal. The depthof the injury determines whether it is a first, second, or third degree burn.First degree burns are mildest. Symptoms are slight pain, redness, tenderness, and increasedtemperature of the affected area.Second degree burns are more serious. The inner skin may be damaged, resulting in blistering,severe pain, some dehydration, and possible shock.Third degree burns are worst of all. The skin is destroyed, and possibly also the tissue and musclebeneath it. The skin may be charred, or it may be white and lifeless (from scalds). After the initial injury,pain may be less severe because of destroyed nerve ends. The person may have chills. Some form ofshock will result.Probably the most important aspect is the extent of the burned area. A first degree burn covering alarge area could be more serious than a small third degree burn. A sunburn, for example, ranging frommild to serious, is easily obtained, particularly if you are not accustomed to the exposure. If you were tofall asleep while sunbathing, second degree burns, or even third degree burns of a possibly fatal nature,could result.The most effective immediate treatment of burns and of pain is to immerse the burned area in coldwater or to apply cold compresses if immersion is impracticable. Cold water not only minimizes pain, butalso reduces the burning effect in the deeper layers of the skin. Gently pat dry the area with lint-free clothor gauze. Aspirin is also effective for the relief of pain. Continue treatment until no pain is felt when theburned area is exposed to the air.1-16
Burn victims require large amounts of water, which should be slightly salted. Because of the natureof the injury, most burns are sterile. The best treatment for uninfected burns, therefore, is merely toprotect the area by covering it with the cleanest (preferably sterile) dressing available. Never applyointments to a burn nor use petrolatum gauze.Do not attempt to break blisters or to remove shreds of tissue or adhered particles of charredclothing. Never apply a greasy substance (butter, lard, or petroleum jelly), antiseptic preparations, orointments. These may cause further complications and interfere with later treatment by medicalpersonnel.HeatstrokeSunstroke is more accurately called heatstroke since a person does not have to be exposed to the sunfor this condition to develop. It is a less common but far more serious condition than heat exhaustion,since it carries a 20 percent fatality rate. The main feature of heatstroke is the extremely high bodytemperature, 105º F (41º C) or higher, that accompanies it. In heatstroke, the victim has a breakdown ofthe sweating mechanism and is unable to eliminate excessive body heat built up while exercising. If thebody temperature rises too high, the brain, kidneys, and liver may be permanently damaged.Sometimes the victim may have preliminary symptoms, such as headache, nausea, dizziness, orweakness. Breathing will be deep and rapid at first, later shallow and almost absent. Usually the victimwill be flushed, very dry, and very hot. The pupils will be constricted (pinpoint) and the pulse fast andstrong. Figure 1-10 compares these symptoms with those of heat exhaustion.Figure 1-10.—Symptoms of heatstroke and heat exhaustion.When you provide first aid for heatstroke, remember that this is a true life-and-death emergency. Thelonger the victim remains overheated, the higher the chances of irreversible body damage or even deathoccurring. First aid treatment for heatstroke is designed to reduce body heat.Reduce body heat immediately by dousing the body with cold water, or applying wet, cold towels tothe whole body. Move the victim to the coolest possible place and remove as much clothing as possible.Maintain an open airway. Place the victim on his/her back, with the head and shoulders slightly raised. Ifcold packs are available, place them under the arms, around the neck, at the ankles, and in the groin.Expose the victim to a fan or air-conditioner since drafts will promote cooling. Immersing the victim in acold water bath is also effective. Give the victim (if conscious) cool water to drink. Do not give any hot1-17
