    Abstract:
    Negative-pressure wound therapy (NPWT) over split thickness skin grafts can control exudate, decrease infection rates, and improve revascularization. However, no study specifically addresses differences in outcomes between meshed/perforated and non-meshed autologous skin grafts dressed with NPWT. Through retrospective chart review, patients undergoing autologous split thickness skin grafting with a NPWT dressing for any burn injury over a 10-month period were identified. Data on etiology, graft take, meshed/perforated or non-meshed graft, graft size, and seroma/hematoma incidence were collected. Our study included 123 patients who had STSG with NPWT and consisted of 57% males, 57% Caucasian, and an average age of 41. Burn injury etiologies consisted of scald (55%), chemical (25%), flame (15%), and contact (5%). Average 2nd degree TBSA in our cohort was 2.34%, 3rd degree TBSA 4.50%, and total TBSA 5.35%. 66.7% of patients received non-meshed grafts, and these patients had an average graft area of 76.5 cm2. 33.3% of patients received meshed grafts, with an average graft area of 163.5 cm2. Non-meshed burn grafts were significantly smaller than meshed grafts (P = .04). There was 100% graft take and 0% seroma/hematoma formation in all patients. Data was analyzed using an unpaired student's T test and ANOVA testing. There were no statistically significant differences in patient demographics, or burn etiology. There exist many options for dressings after repair of burn injuries, each with its own unique advantages. There were, however, no differences in graft take or incidence of seroma/hematoma formation using a NPWT dressing over autologous meshed grafts vs non-meshed grafts. Our data shows that NPWT use as a bolster dressing is safe and efficacious overlying meshed skin grafts and non-meshed grafts.
