[Morphology of healed burns treated by different methods]

The dynamics of burn wound healing was studied on biopsies from the wound area in 30 patients treated by open methods (treatment under conditions of abacterial environment and in a cabinet with laminar air). Twenty patients were treated by applications on the wound of ointment bandages. Under the bandages, the crust formed on the burn surface was infiltrated with polymorphonuclear leukocytes. When patients with burns over 10-25% of the body surface were treated in abacterial environment, a thin dry crust developed on the burn wound surface with small accumulations of microflora in its external layers. The granulation tissue filling the wound after early necrectomy contains numerous vessels and cell elements. In extensive burns (35-50% of the body surface) the granulation tissue fills the wound cavity incompletely, as separate islets.
