Previous studies have demonstrated higher infection rates following elective procedures on the foot and ankle as compared with procedures involving other area of the body. Previous studies also have documented the difficulty of eliminating bacteria from the forefoot prior to surgery. The purpose of the present study was to ascertain that preoperative chlorhexidine bathing provide significant local flora reduction than placebo in elective foot and ankle surgery.

From October 2005 to October 2006, a prospective study was undertaken to evaluate 50 consecutive patients undergoing planned, elective surgery of the foot and ankle. 50 patients were prospectively enrolled and randomly assigned to have preoperative footbath with Chlorhexidine Gluconate (Hibitane) (Group 1) or placebo (Group 2). Culture swabs were taken from all web spaces, nail folds, toe surfaces and proposed surgical incision sites before the preoperative antiseptics bath, during the procedures and immediately completion of surgery.

50 patients were enrolled (mean age: 42.6 years; range: 19–85; F: M = 29:21). 25 patients are assigned to each groups. 100% bacterial isolation preoperatively in both groups prior to antiseptics bathing. In group1, bacteria grew on intraoperative culture in 60% cases and 0% in immediate post-operative culture. In group 2, 96% in intraoperative swab culture and 16% in postoperative swab culture. The intraoperative swab culture bacterial count is statistically significant (p= 0.002). The postoperative swab culture bacterial count is marginally significant (p=0.055) when comparing 2 groups. No complications were recorded in both groups.

These data indicate that chlorhexidine provides better reduction in skin flora than placebo. Based of these data, we recommend the use of chlorhexidine footbath as well as the surgical preparatory agent for the foot and ankle surgery.
