96 Poly-dl-lactide Copolymer-dressing Use on Burn Wounds and Skin Graft Donor Sites - An Institutional Review

INTRODUCTION: In burn surgical care, wound coverage and the corresponding dressing are paired to maximize the ability to promote re-epithelization, minimize pain and patient discomfort, dressing change frequency and overall cost. This dressing, a copolymer material based on DL lactic acid, has been described as a reliable alternative dressing for partial thickness burns as well as skin graft donor sites with comparable wound-healing quality and duration. Our aim is to assess outcomes results of this copolymer dressing at our institution, as applied to partial thickness burn wounds and graft donor sites. METHODS: We performed a retrospective analysis of 55 adult patients admitted between January 1, 2020 to August 25, 2021 for the treatment of partial thickness burns that were managed with a poly-DL-lactide copolymer skin substitute at the burn wound and/or autograft donor site. Three study groups were established based on application site: wound only (group 1), donor site only (group 2), and both (group 3). We assessed operative times, infections rates, complications, length of stay, readmission rates, and mortality. RESULTS: Preliminary data of 40 patients shows clinically similar results for analgesic requirements, operative length, and hospital LOS between group 1 and group 3. Group 2 showed higher analgesic requirements, lower operative times, a lower LOS, and lower readmission rates. Group 3 shows higher pain levels and longer operative times, when compared with groups 1 and 2, but lower readmission rates than group 1. CONCLUSIONS: The poly-DL-lactide copolymer skin substitute offers reliable wound coverage for a partial thickness burns while also reducing frequency of dressing changes and associated pain correlating to reduced length of hospital stay and wound healing interval.
