Single-Blind, Prospective, Randomized Study of Cefmetazole and Cefoxitin in the Treatment of Postcesarean Endometritis

Objective: The purpose of this study was to compare the clinical efficacy and safety of cefmetazole given by IV push with that of parenterally administered cefoxitin for the treatment of endometritis following cesarean delivery. Methods: In a single-blind, multicenter, prospective, randomized study, 355 patients with endometritis after cesarean delivery were enrolled and received medication. Administered was either cefmetazole sodium, 2 g by IV push over 1 min q 8 h, or cefoxitin sodium, 2 g IV q 6 h in a 2:1 ratio. The patients were followed for clinical responses and side effects. Results: The cure rate for cefmetazole was 89% and for cefoxitin it was 79% (P = 0.006). The adverse events were similar in both groups. Conclusions: Cefmetazole was significantly more effective than cefoxitin in the treatment of endometritis following cesarean delivery.
