Abstract:[Objective] To evaluate the clinical efficacy of debridement combined with vacuum-assisted closure (VAC) for limb wound. [Methods] A retrospective study was performed on 64 patients who received surgical treatment of limb wound in our hospital from October 2017 to November 2019. According to the consequence of preoperative doctor-patient communication, 32 patients were treated with debride- ment combined with VAC (the VAC group) , while the remaining 32 patients were treated with debridement combined with conventional dressing change (the conventional group) . The documents regarding to perioperative period, follow-up and laboratory tests were compared between the two groups. [Results] All patients in both groups had the two-stage operations performed successfully without serious complica- tions. The VAC group consumed slight longer operation time in the first stage than the conventional group, but without a statistically signifi- cant difference between them (P>0.05) . The VAC group proved significantly superior to the conventional group in terms of number of dress- ing change, exudation grade, granulation grade, interval between two operations, time of the second operation, wound healing and hospital stay (P<0.05) . In addition, the VAC group resumed full weight-bearing activity significantly earlier than the conventional group (P<0.05) . The VAS scores, local scar, and adjacent joint function improved significantly over time in both groups (P<0.05) , which in the VAC group was significantly superior to the conventional group at 3 months postoperatively (P<0.05) , whereas became not statistically significant be- tween the two groups at 6 and 12 months postoperatively (P>0.05) . With respect of laboratory tests, the WBC, NEU, CRP, and ESR de- creased significantly over time in both groups (P<0.05) , which in the VAC group were significantly better than those in conventional group before the second stage operation (P<0.05) . [Conclusion] The VAC has advantages of shortening recovery time of limb wound, reducing the risk of infection and the incidence of complications over the conventional dressing change.
