This important work from colleagues in Fukuoka suggests what many have believed. Aggressive efforts at serial debridement and skin grafting appears to lead to more long-term wound closure in very high risk patients.
Please note that the control group in this study received what most could consider above-and-beyond exceptional care (NPWT, debridement, vascular surgery).
Background: A long period is generally required for ischemic ulcer to heal after revascularization. The strategy of postoperative wound care can affect wound healing. This study was conducted to investigate the degree to which aggressive wound care (AWC) by a team of multidisciplinary specialists actually shortens the time to wound healing and increases the rate of wound healing in limbs undergoing surgical bypass for ischemic tissue loss in a real clinical setting.
Methods: A total of consecutive 126 patients undergoing infrainguinal bypass for tissue loss from April 2011 to March 2015 were reviewed. Prior to March 2013, standard wound care (SWC) including typical daily dressing change with disinfection and irrigation, occasional surgical debridement, and negative pressure wound therapy (when necessary) was performed by vascular surgeons. Thereafter, in addition to SWC, AWC including intense daily bedside surgical debridement under a sciatic nerve block by an anesthesiologist and active skin grafting by a dermatologist, if necessary, was performed. Wound healing and major amputation were defined as the end points. The 1-year outcomes of the 2 groups were calculated using the Kaplan Meier method and compared, and the significant predictors of each outcome were determined by a Cox proportional hazards analysis.
Results: The wound healing of the AWC group was superior to that of the SWC group (AWC versus SWC, 1-year wound healing rate: 92% vs. 80%; mean wound healing time: 48 days vs. 82 days; P = 0.011), and no significant difference between the 2 regimens in the freedom from major amputation was observed. AWC, Rutherford 5, no wound infection, normal serum albumin, direct angiosome, and cilostazol use were significant predictors of wound healing, and female gender and no cilostazol use were significant predictors of major amputation by a multivariate analysis.
Conclusions: Aggressive wound care by the team consisting of multidisciplinary specialists remarkably shortened the time to wound healing and increased the rate of wound healing within 1 year.
