Effect of irrigation or intravenous antibiotic prophylaxis on infectious morbidity at cesarean section

Abstract

The efficacy of intraoperative irrigation with cefamandole nafate at cesarean section was evaluated in a prospective, randomized double-blind study. Two hundred and eight patients were treated with antibiotic irrigation and intravenous placebo or with perioperative intravenous cefamandole and irrigated with normal saline. The rate of endometritis was 10.9% in the irrigation group and 14% in the intravenous group, but the difference was not statistically significant. The rate of any infection, the number of days with fever, additional hospitalization days, and number of antibiotics used for treatment were similar in the two groups. It thus was concluded that irrigation with antibiotic is equal but not superior to perioperative intravenous antibiotics.
