Prevention of wound infection in abdominal operations by peroperative antibiotics or povidone-iodine. A controlled trial

Abstract

The wound-infection rate after abdominal operations was compared in 113 patients randomly allocated to an untreated control group, a group receiving preoperative lincomycin and tobramycin, or a group receiving local instillation of povidone-iodine. The wound-infection rate was 8.1% in 37 patients receiving antibiotics, 42.1% in 38 untreated controls, and 39.5% in 38 patients in the povidone-iodine group.
