These measures will often prevent a grossly injured portion of skin dying, and will ensure asepticity should it do so. In the event of the skin giving way, the same form of dressing should be continued till the slough has separated and a healthy granulating surface is formed. The protective dressing appropriate to a healing sore is then substituted. Pressure sores are treated on the same lines.
The third period begins when the sloughs separate, usually between the seventh and fourteenth days, and lasts till the wound heals, its duration depending upon the size, depth, and asepticity of the raw area.
Any blood vessel that is punctured should be cut across and tied; and divided muscles, tendons, or nerves must be sutured. After hæmorrhage has been arrested, iodoform and bismuth paste is rubbed into the raw surface, and the wound closed. If there is any reason to doubt the asepticity of the wound, it is better treated by the open method, and a Bier's bandage should be applied.
In extensive ulcers resulting from recent burns, if the granulations are healthy and aseptic, skin-grafts may safely be placed on them directly. If, however, their asepticity cannot be relied upon, it is necessary to scrape away the superficial layer of the granulations, the young fibrous tissue underneath being conserved, as it is sufficiently vascular to nourish the grafts placed on it.
