The _prognosis_ in burns depends on (1) the superficial extent, and, to a much less degree, the depth of the injury. When more than one-third of the entire surface of the body is involved, even in a mild degree, the prognosis is grave. (2) The situation of the burn is important. Burns over the serous cavities--abdomen, thorax, or skull--are, other things being equal, much more dangerous than burns of the limbs. The risk of œdema of the glottis in burns about the neck and mouth has already been referred to. (3) Children are more liable to succumb to shock during the early period, but withstand prolonged suppuration better than adults. (4) When the patient survives the shock, the presence or absence of infection is the all-important factor in prognosis. #Treatment.#--The _general treatment_ consists in combating the shock. When pain is severe, morphin must be injected. _Local Treatment._--The local treatment must be carried out on antiseptic lines, a general anæsthetic being administered, if necessary, to enable the purification to be carried out thoroughly. After carefully removing the clothing, the whole of the burned area is gently, but thoroughly, cleansed with peroxide of hydrogen or warm boracic lotion, followed by sterilised saline solution. As pyogenic bacteria are invariably found in the blisters of burns, these must be opened and the raised epithelium removed. The dressings subsequently applied should meet the following indications: the relief of pain; the prevention of sepsis; and the promotion of cicatrisation. An application which satisfactorily fulfils these requirements is _picric acid_. Pads of lint or gauze are lightly wrung out of a solution made up of picric acid, 1½ drams; absolute alcohol, 3 ounces; distilled water, 40 ounces, and applied over the whole of the reddened area. These are covered with antiseptic wool, _without_ any waterproof covering, and retained in position by a many-tailed bandage. The dressing should be changed once or twice a week, under the guidance of the temperature chart, any portion of the original dressing which remains perfectly dry being left undisturbed. The value of a general anæsthetic in dressing extensive burns, especially in children, can scarcely be overestimated. Picric acid yields its best results in superficial burns, and it is useful as _a primary dressing_ in all. As soon as the sloughs separate and a granulating surface forms, the ordinary treatment for a healing sore is instituted. Any slough under which pus has collected should be cut away with scissors to permit of free drainage.
