Microbiology and healing of the occluded skin-graft donor site.

Abstract

Delayed healing of skin-graft donor sites may be costly and life-threatening, especially in patients with large body surface area burns. A donor site dressing should maximize the ability of the wound to heal without increasing the risk of local infection, systemic infection, or both. Specifically, the possibility of a secondary infection may either slow the healing process or ultimately convert the donor site into a full-thickness skin loss. A number of materials ranging from gauze to biologicals have been investigated for use as donor site dressings. The use of hydrocolloids for donor sites has been widely studied and has shown improved healing rates over the rates reported for conventional dressings. Our recent study using hydrocolloids confirmed earlier research that showed fewer infections and more rapid donor site healing.
