Single-dose cefazolin versus cefonicid for antibiotic prophylaxis in cesarean delivery

The purpose of this prospective investigation was to compare a single intravenous dose of cefazolin to a single dose of cefonicid as prophylaxis for women having unscheduled cesarean delivery. In a double-blind, randomized design, 96 patients were assigned to receive a 1-g dose of cefazolin and 103 patients were designated to receive a 1-g dose of cefonicid. The antibiotics were administered after delivery of the infant. The two groups were comparable with respect to recognized risk factors for postcesarean infection. There were no statistically significant differences between the groups in the incidence of standard febrile morbidity, endomyometritis, urinary tract infection, wound infection, and bacteremia. There were also no significant differences between the groups in the fever index or the duration of hospitalization. We conclude that cefazolin and cefonicid provide a similar degree of prophylaxis against infection in patients having unscheduled cesarean delivery.
