Prevention of surgical site infections is critical in deep brain stimulation (DBS). In the present study, we tested the ability of a self-administered preoperative alcohol-based (70% ethyl alcohol) preparation to reduce the rate of postoperative infection after DBS surgery.This Institutional Review Board-approved retrospective review was conducted at our institution between January 2005 and October 2007 (mean follow-up, 23 months). The participants comprised a consecutive sample of 172 patients with movement disorders who underwent DBS surgery at our institution. Starting in January 2007, all patients were required to use the alcohol-based preparation. These patients (n = 48) were instructed to self-administer the wash on the night before surgery and the morning of surgery. Before this time, no self-administered wash was used (n = 122).There was no difference in preoperative skin cleansing between the 2 groups, and all patients received intravenous antibiotics immediately before and after surgery for 24 hours. We compared the rate of postoperative infection in the 2 groups and reviewed other possible factors underlying infection. We found 11 cases of infection (6.47%), all in the group without the preoperative antiseptic wash. The infection rate was 9.02% in the group without the preoperative wash and 0 in the group with the preoperative wash (P < .029). There was no difference between the 2 groups in terms of mean age, duration of operative procedure, or number of microelectrode tracts attempted.Our results support the incorporation of this self-administered antiseptic wash into our standard antiseptic protocol for patients undergoing DBS surgery.
