Cefazolin versus cefazolin plus metronidazole for antibiotic prophylaxis at cesarean section.

Abstract

Although prophylactic antibiotic medications have been shown to reduce the incidence of postoperative infectious morbidity after cesarean delivery, the most effective regimens have not been established. The purpose of this investigation was to compare the efficacy and costs of prophylaxis with cefazolin alone with cefazolin plus metronidazole.
