A randomized prospective study of antibiotic prophylaxis during abdominal surgery.

The safety and efficacy of intravenous cefmetazole for prophylaxis before abdominal operations were compared with those of intravenous cefoxitin in a randomized, prospective clinical study. Eighty-nine evaluable patients were enrolled. These patients underwent primarily clean/contaminated (56%) and contaminated (39%) operations. A total of three (3%) patients developed postoperative wound infections. Two patients (2%) developed non-life-threatening adverse drug reactions. There were no life-threatening adverse drug reactions. There were no significant differences between the cefmetazole and cefoxitin study groups. Cefmetazole appears to be as safe and as efficacious as cefoxitin antibiotic in prophylaxis for intra-abdominal operations.
