Negative-Pressure Wound Therapy Improves Take Rate of Skin Graft in Irregular, High-Mobility Areas: A Randomized Controlled Trial

Background: Tie-over bolster dressing to secure a skin graft is associated with low graft take rates in irregular, high-mobility areas and suboptimal recipient wound beds. Negative-pressure wound therapy has become a well-established method to secure the graft, with a graft take rate of this method reported to be 96.7 percent. However, comparative efficacies between the two methods on irregular, high-mobility areas are yet to be determined. Methods: Patients eligible for skin graft were randomly assigned to receive either negative-pressure wound therapy or tie-over bolster dressing between December of 2014 and December of 2015. The primary outcome was determined by the take rate of skin grafts between postoperative days 5 and 7. The secondary outcomes were dressing time and postoperative complications, including hematoma, seroma, infection, displacement, and necrosis. Results: A total of 86 patients were assigned to receive either negative-pressure wound therapy (n = 43) or tie-over bolster dressing (n = 43) for skin graft treatment. Negative-pressure wound therapy significantly improved the take rate of grafts as compared with tie-over bolster dressing (97.2 versus 90.2 percent; p = 0.005). The improvements came from the grafts in irregular, high-mobility areas in the respective groups (97.6 versus 81.7 percent; p
