Comparison of Negative-Pressure Wound Therapy and Gradual Wound Approximation Treatments for Infected Fasciotomy Wounds.

Abstract

Negative-pressure wound therapy (NPWT) and gradual wound approximation (GWA) are effective and reliable methods of treating fasciotomy wounds. However, the effectiveness of these 2 methods in treating infected wounds remains unclear. The aim of our study was to compare these 2 delayed primary closure methods of treating infected fasciotomy wounds on the limbs. Patients who underwent fasciotomy surgery on the extremities after sustaining crushing injuries in the 2023 Kahramanmaraş-centered earthquakes and who were referred owing to infected open wounds during follow-up were included in the study. Patients who completed the wound closure process at our clinic were divided into 2 groups: the NPWT and GWA groups. Using retrospectively collected data, the groups were compared in terms of demographic characteristics, time until wound closure, number of surgeries, skin graft requirements, and complications. Laboratory parameters were also examined. Thirteen patients, (with 21 wounds) who underwent NPWT and 14 (with 22 wounds) who underwent GWA, were examined. The average age of the NPWT group was 32.85 ± 18.37 years, whereas that of the GWA group was 25.21 ± 16.31 years. The number of surgeries in the NPWT and GWA groups were 5.38 ± 2.11 and 4.23 ± 1.27, respectively, and the difference was statistically significant (P = .040). The average wound closure times of the NPWT and GWA groups (P = .0210) (11.00 ± 4.86 days and 8.27 ± 2.41 days, respectively) also differed significantly. Skin grafting was performed in 5 patients in the NPWT group and 2 in the GWA group. There were no significant differences between the 2 groups in terms of skin graft requirements or complication rates. NPWT and GWA are effective and reliable methods of closing infected fasciotomy wounds. Closure of these wounds can be achieved in a shorter time and with fewer surgeries using GWA than using NPWT.
