Patients were given a 4-oz (118-mL) bottle of 4% chlorhexidine gluconate (Hibiclens) during preoperative teaching and instructed to use it during a shower the night before and the morning of surgery. Written instructions were as follows. “To use Hibiclens, open the bottle and pour some solution into your hand or a washcloth. Move away from the shower stream to avoid rinsing off the Hibiclens too soon. Rub it gently over your body from your neck to your waist and rinse. Don’t let the solution get into your eyes, ears, mouth, or genital area. Don’t use any other soap. Dry yourself off with a clean towel after your shower.”
Preoperative intravenous antibiotics included 2 gm cefotetan, re-dosed every 6 h intraoperatively. Patients with penicillin allergy received clindamycin and gentamicin.
