Efficacy of Mepliex Ag Versus Xeroform As A Split-Thickness Skin Graft Donor Site Dressing: Bad Habits Die Hard.

Autografting with split-thickness skin grafts (STSG) remains an essential procedure in burn and reconstructive surgery. The process of harvesting STSG, however, leaves behind a donor site, an exposed area of partial-thickness dermis left to heal by secondary intention. There has yet to be a consensus amongst surgeons regarding optimal management of the donor site. The ideal donor site dressing is one that allows for expeditious healing while minimizing pain and infection. Despite numerous studies demonstrating the superiority of moist wound healing, many surgeons continue to treat STSG donor sites dry, with petroleum-based gauze. In this study, two burn centers performed a retrospective review of burn patients whose STSG donor sites were treated with either Xeroform or Mepilex Ag dressings. Infections were documented and in a subgroup analysis of patients, postoperative pain scores were noted and total opiate usage during hospitalization was calculated. Analysis revealed an overall infection rate of 1.2% in the Mepilex Ag group and 11.4% in the Xeroform group (p<0.0001). Patients with Xeroform donor site dressings had increased odds of donor site infection (OR=10.8, p=0.002). In subgroup analysis, there were no significant differences in maximum pain scores between Mepilex Ag and Xeroform groups, nor were there differences in opiate usage. STSG donor sites dressed with silver foam dressings have a lower rate of donor site infection relative to those dressed with petroleum-based gauze. Moist donor site dressings such as foam dressings (including Mepilex Ag) should be the standard of care in STSG donor site wound care.
