Abstract: | ObjectiveRecent literature has shown that negative pressure wound therapy with instillation and dwell time (NPWTi-d) is a valid method of managing complex wounds and gained increasingly wider interest due in part to the increasing complexity of wounds. The purpose of this case study was to obtain information on the profile of NPWTi-d in necrotizing fasciitis patients, investigate the role it play in wound bed preparation, length of hospital stay and number of debridement operations.MethodsNPWTi-d has been used in patients with necrotizing fasciitis with either normal saline or Prontosan® solution and complete the treatment were involved in the present study. Following aggressive surgical debridement, NPWTi-d was initiated by instilling solution with a set dwell time of 5–10 min, followed by continuous NPWT of ?125 mm Hg for 3–5 h. The system was changed on a 3–5 days schedule until sufficient granulation tissue was evident. Patients received systemic antibiotics and underwent wound debridement as indicated. Data of wound bed preparation, length of hospital stay, duration of NPWTi-d therapy, number of surgical interventions were collected retrospectively from patient medical records.ResultsA total of 32 patients with diagnosis of necrotizing fasciitis received NPWTi-d were included. Granulation tissue was found to be sufficient in 9–16 days. The mean duration of NPWTi-d therapy was 12.5 days prior to wound closure by split-thickness autograft (n = 21), suture (n = 9), or flap transplantation (n = 2).Patients received NPWTi-d treatment over a period of 8–16 days. The mean length of hospitalization was 22.8 days. All wounds were successfully closed and no recurrence of infection or adverse event was observed during NPWTi-d treatment.ConclusionIn these patients, NPWTi-d facilitates wound cleansing and wound bed preparation and offers the clinician an additional tool for the management of necrotizing fasciitis. Further well designed prospective investigations with low risk of bias are needed to confirm these findings in the future work. |
