Clinical application of improved VSD and VSD in the treatment of SSI after abdominal surgery: A retrospective randomized clinical study

Abstract

By comparing the efficacy and cost of improved vacuum-sealing drainage devices and vacuum-sealing drainage (VSD) devices in the treatment of postoperative abdominal surgical site infection, the clinical applicability and promotion of improved vacuum-sealing drainage devices were assessed. In our institution, between October 2019 and December 2021, 55 patients with surgical site infection after abdominal surgery were retrospectively analyzed, including 30 patients treated with improved VSD and 25 patients treated with VSD. The efficacy of wound healing, total dressing change cost throughout therapy, total hospital costs, hospital days, and bacterial culture results of wound secretions before and after treatment were compared between the 2 groups. Both groups achieved wound healing following vacuum sealing-drainage treatment, with no significant differences in wound healing time or secondary suture rate. However, the total hospitalization and dressing change costs in the improved VSD group were significantly lower than those in the VSD group. Similar to VSD, improved VSD is effective in the treatment of surgical site infections after abdominal surgery. Compared with VSD, the improved VSD device has lower dressing change costs and total hospitalization costs during the treatment process. The improved VSD has a wide range of applications and is suitable for clinical use and promotion.
