Skin-Sparing Debridement for Necrotizing Fasciitis in Children

Background: Necrotizing fasciitis is a serious soft-tissue infection associated with sepsis and tissue destruction. Surgical management usually requires extensive debridement of necrotic fascia and overlying skin, with significant aesthetic and functional consequences. The authors review the outcome of all recent cases of necrotizing fasciitis treated with skin-sparing debridement at their institution. Methods: The authors conducted a retrospective review of all of their cases of necrotizing fasciitis treated with skin-sparing debridement. Medical records were evaluated with a standard form gathering relevant demographic and clinical data. All cases were confirmed as necrotizing fasciitis histologically. Results: Ten patients were admitted with a diagnosis of necrotizing fasciitis. The median age of the patients was 4.9 years (range, 1.7 to 15.1 years). The majority of initial lesions were caused by chickenpox, mostly on the trunk. Interval from admission to surgery was 6 hours (range, 1 to 27.5 hours), with a median hospital stay of 11 days (range, 5 to 43 days). Median fasciectomy was 2.5 percent (range, 1 to 15 percent) of total body surface area, with a median skin excision of 0.25 percent of total body surface area (range, 0.1 to 3 percent). All patients received intravenous amoxicillin/clavulanic acid plus clindamycin. Delayed direct closure was possible for all patients. Median follow-up was 17 months (range, 3 to 79 months). There was no death in this series. Conclusion: This surgical management restricts skin excision to the area of definite skin necrosis, limiting skin excision to one-tenth of excised fascia, with long-term favorable cosmetic and functional results.
