A NOTE ON WOUND HEALING UNDER DRESSINGS WITH SPECIAL REFERENCE TO PERFORATED-FILM DRESSINGS

[摘要] The healing of a shallow skin wound involves the formation of a dry scab incorporating dermal tissue, dehydrated by exposure to tho air. Occlusive dressings, by keeping the wound surface moist, greatly modify the pattern of healing. Under a perforated-film dressing, the wound surface in the pig is apparently moist beneath the intact film and dry opposite the holes in the film. Thus histological sections of wounds covered by Telfa dressings show regularly distributed areas of dry dermal tissue corresponding to the holes in the polyester film lying on the wound surface.
