Clinical application of Improved VSD and VSD in the treatment of SSI after abdominal surgery

Abstract AimTo explore the feasibility of clinical application and promotion of Improved vacuum sealing drainage devices 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.Methods from October 2019 to December 2021, we retrospectively analyzed 55 patients with surgical site infection after abdominal surgery in our hospital, including 30 patients treated with improved VSD and 25 patients treated with VSD. Wound healing efficacy, total dressing change cost during treatment, total hospitalization cost, hospital days, and bacteria culture results of wound secretions before and after treatment were compared between the two groups. ResultsWound healing was achieved in both groups after vacuum sealing drainage treatment, and there was no significant difference in wound healing time and secondary suture rate (P > 0.05), but the hospitalization cost and dressing change cost of the Improved VSD group were significantly lower than those of VSD, with significant difference (P < 0.05).ConclusionsThe efficacy of simple VSD in the treatment of surgical site infection after abdominal surgery is similar to that of VSD. Compared with VSD, the total dressing change cost and hospitalization cost of improved VSD device in the treatment process are lower. Improved VSD has a wider application scope and is suitable for clinical application and promotion.
