Occlusive drainage system for split-thickness skin graft: A prospective randomized controlled trial

Abstract

BackgroundSplit-thickness skin grafts are widely used in reconstruction of large area defects. Conventional postoperative recipient site care includes saline-moistened gauze with a protective layer of petroleum gauze and splints for immobilization. This method causes pain while changing the dressing. We designed a better occlusive drainage system for split-thickness skin grafts.We compared the treatment effect and subjective evaluation of our occlusive drainage system with that of the conventional method for coverage of split-thickness skin grafts. MethodsA randomized controlled trial was carried out in patients who received split-thickness skin grafts. Patients aged 24–76 years were randomly assigned to the occlusive drainage system or the conventional indirect wet dressing method. The status of graft take, pain, and subjective evaluations were compared. ResultsTwenty-eight participants were enrolled, with 14 in each group. The percentage of graft take was no difference between the 2 groups. No wound infection developed. Patients in the occlusive drainage system group experienced less pain and greater satisfaction. All patients followed up for at least 3 months, and no hypertrophic scar formation was noted. ConclusionComparing with the indirect wet dressing method, this new method is practical for covering split-thickness skin grafts, causes less pain, and provides a better experience for patients.
