A prospective analysis of the association between indwelling surgical drains and surgical site infection in plastic surgery

Introduction Many surgeons fear that closed-suction drains serve as a portal for bacterial entry into surgical spaces. Despite a lack of supporting evidence, postoperative antibiotics are often prolonged while drains remain in place. Methods Medical records of all patients who underwent intraoperative Jackson-Pratt drain placement and sterile removal over a 12-month period were prospectively analyzed. Results Fifty-four patients with 101 drains were included. Drains were in place for 5 to 43 days [mean (SD), 13.5 (6.3) days]. Sixty-three percent of drains had positive cultures. All patients received perioperative antibiotics. Thirty-nine patients received postoperative antibiotics [mean (SD), 13.8 (13.8) days]. There were 2 cases of cellulitis. One patient required reoperation. Conclusions Sixty-six drains (65.3%) were placed in the presence of prosthetic material. Although nearly two thirds of drains were colonized with bacteria, our wound infection rate was extremely low (5.6%). Thus, closed-suction drains may be left in place for an extended period without increasing the risk of infection, even in the presence of prosthetic material.
