See also:BURNS AND SCALDS . A See also:burn is the effect of dry See also:heat applied to some See also:part of the human See also:body, a See also:scald being the result of moist heat. Clinically there is no distinction between the two, and their See also:classification and treatment are identical. In See also:Dupuytren's classification, now most generally accepted, burns are divided into six classes according to the severest part of the See also:lesion. Bums of the first degree are characterized by severe See also:pain, redness of the skin, a certain amount of swelling that soon passes, and later exfoliation of the skin. Burns of the second degree show vesicles (small blisters) scattered over the inflamed See also:area, and containing a clear, yellowish fluid. Beneath the vesicle the highly sensitive papillae of the skin are exposed. Burns of this degree leave no scar, but often produce a permanent discoloration. In burns of the third degree, there is a partial destruction of the true skin, leaving sloughs of a yellowish or See also:black See also:colour. The pain is at first intense, but passes off on about the second See also:day to return again at the end of a See also:week, when the sloughs See also:separate, exposing the sensitive See also:nerve filaments of the underlying skin. This results in a slightly depressed cicatrix, which happily, however, shows but slight tendency to contraction. Burns of the See also:fourth degree, which follow the prolonged application of any See also:form of intense heat, involve the See also:total destruction of the true skin. The pain is much less severe than in the preceding class, since the nerve endings have been totally destroyed. The results, however, are far more serious, and the healing See also:process takes See also:place only very slowly on See also:account of the destruction of the skin glands. As a result, deep puckered scars are formed, which show See also:great tendency to See also:contract, and where these are situated on See also:face, See also:neck or See also:joints the resulting deformity and loss of See also:function may be extremely serious. In burns of the fifth degree the underlying muscles are more or less destroyed, and in those of the See also:sixth the bones are also charred. Examples of the last two classes are mainly provided by epileptics who fall into a See also:fire during a See also:fit. The clinical See also:history of a severe burn can be divided into three periods. The first See also:period lasts from 36 to 48 See also:hours, during which See also:time the patient lies in a See also:condition of profound See also:shock, and consequently feels little or no pain. If See also:death results from shock, See also:coma first supervenes, which deepens steadily until the end comes. The second period begins when the effects of shock pass, and continues until the See also:slough separates, this usually taking from seven to fourteen days. Considerable See also:fever is See also:present, and the tendency to every See also:kind of complication is very great. See also:Bronchitis, See also:pneumonia, See also:pleurisy, See also:meningitis, intestinal See also:catarrh, and even ulceration of the duodenum, have all been recorded. Hence both See also:nursing and medical attendance must be very See also:close during this time. It is probable that these complications are all the result of septic infection and absorption, and since the See also:modern antiseptic treatment of burns they have become much less See also:common. The third period is prolonged until recovery takes place. Death may result from septic absorption, or from the See also:wound becoming infected with some organism, as See also:tetanus, See also:erysipelas, &c. The See also:prognosis depends chiefly on the extent of skin involved, death almost invariably resulting when one-third of the total area of the body is affected, however superficially. Of secondary but still See also:grave importance is the position of the burn, that over a serous cavity making the future more doubtful than one on a See also:limb. Also it must be remembered that See also:children very easily succumb to shock. In treating a patient the condition of shock must be attended to first, since from it arises the See also:primary danger. The sufferer must be wrapped immediately in hot blankets, and See also:brandy given by the mouth or in an enema, while See also:ether can be injected hypodermically. If the See also:pulse is very See also:bad a saline infusion must be administered. The clothes can then be removed and the burnt surfaces thoroughly cleansed with a very mild antiseptic, a weak See also:solution of lysol acting very well. If there are blisters these must be opened and the contained effusion allowed to See also:escape. Some surgeons leave them at this See also:stage, but others prefer to remove the raised epithelium. When thoroughly cleansed, the wound is irrigated with sterilized saline solution and a dressing subsequently applied. For the more superficial lesions by far the best results are obtained from the application of See also:gauze soaked in picric See also:acid solution and lightly wrung out, being covered with a large antiseptic See also:wool See also:pad and kept in position by a bandage. Picric acid 12 drams, See also:absolute See also:alcohol 3 oz., and distilled See also:water 40 oz., make a See also:good lotion. All being well, this need only be changed about twice a week. The various kinds of oil once so greatly advocated in treating burns are now largely abandoned since they have no antiseptic properties. The deeper burns can only be attended to by a surgeon, whose aim will be first to bring septic absorption to a minimum, and later to hasten the healing process. Skin grafting has great value after extensive burns, not because it hastens healing, which it probably does not do, but because it has a marked See also:influence in lessening cicatricial contraction. When a limb is hopelessly charred, amputation is the only course. Additional information and CommentsThere are no comments yet for this article.
