ABSTRACT
Five hundred and sixty-six women, consecutively admitted to nine different hospitals for elective abdominal hysterectomy, were randomized to receive a single 2 g i.v. dose of either cefotetan or piperacillin at induction of anesthesia. Five patients were excluded and 561 (287 given cefotetan and 274 given piperacillin) could be evaluated. In 10 patients (5 for each drug) the concentrations of either cefotetan or piperacillin in serum and subcutaneous tissue at the beginning and at the end of surgery and in uterus, salpinx and ovary samples, were microbiologically assessed. No significant differences could be found between cefotetan and piperacillin groups for any of the considered infectious complications (bacteremia, wound or vaginal cuff infection, pelvic cellulitis and febrile morbidity) nor for the pooled data (cefotetan group: 4.9%, piperacillin group: 5.8%, p:NS). As for the concentrations of prophylactic drugs, serum levels throughout surgery were found to be adequate.
