Abstrakt: Background: Chlorhexidine gluconate solution is superior to povidone-iodine for prevention of surgical site infection. However, the overall efficacy of chlorhexidine gluconate for surgical site infection prevention in various types of gastroenterological surgery, as well as the optimal concentration of chlorhexidine gluconate, remain unclear. The aim of the present study was to clarify whether subcutaneous wound soaking with chlorhexidine gluconate would reduce the incidence of surgical site infection associated with gastroenterological surgery in patients with wound classes Ⅱ to Ⅳ.
Methods: Patients were randomly assigned (1:1) to either wound soaking with chlorhexidine gluconate (chlorhexidine gluconate group) or no chlorhexidine gluconate soaking (control group). After closure of the abdominal fascia, gentle subcutaneous soaking of the wound was performed using gauze fully soaked in aqueous 0.05% chlorhexidine gluconate before skin closure. Incisional surgical site infection was diagnosed using the Centers for Disease Control and Prevention criteria. The primary end point was the occurrence of incisional surgical site infection.
Results: Among 363 patients, 245 (67%) underwent laparoscopic surgery. All 363 patients were included-181 in the chlorhexidine gluconate group (49.9%) and 182 (50.1%) in the control group. There were no significant inter-group differences in patient background, the type of procedure, or wound classification. The incidence proportion of incisional surgical site infection was significantly lower in the chlorhexidine gluconate group than in the control group (9.4% vs 19.2%; P = .008).
Conclusion: Subcutaneous wound soaking with chlorhexidine gluconate reduces the incidence of incisional surgical site infection in patients undergoing gastroenterological surgery.
