title: Multicenter trial of prophylaxis with clindamycin plus aztreonam or cefotaxime in gynecologic surgery.
abstract: A prospective, randomized, multicenter study was conducted on the efficacy and safety of two prophylactic antibiotic regimens in both abdominal and vaginal hysterectomy. Patients received three intravenous doses of clindamycin (900 mg) plus either aztreonam (1 g) or cefotaxime (1 g); the doses were given at the induction of anesthesia and 8 and 16 hours later. A total of 170 patients undergoing abdominal hysterectomy and 142 patients undergoing vaginal hysterectomy completed the trial and were evaluated. Following abdominal hysterectomy infections occurred at the operative site in 1.2% of patients given a regimen including aztreonam and in 4.7% of those given a regimen including cefotaxime; the difference between the two groups was not significant. Neither were significant differences observed in the incidence of fever, the incidence of bacteriuria, the need for postoperative antibiotics, or the duration of postoperative hospitalization, although results were slightly better for patients receiving clindamycin plus aztreonam. Following vaginal hysterectomy, slightly but not significantly better results for the same parameters were obtained in the group given clindamycin plus cefotaxime. Diarrhea was the only adverse reaction attributable to antibiotic treatment and occurred more frequently in patients given cefotaxime. It was concluded that the two regimens were similarly effective and safe in preventing infections following hysterectomy.
