[Antibiotic prophylaxis in cesarean section -- piperacillin versus piperacillin/tazobactam in 300 cesarean sections].

Abstract

Introduction: Antibiotic prophylaxis is a standard procedure in obstetric surgery and has been discussed in various investigations. Use of treatment is judged by high efficacy and good tolerance.

Method: In 300 patients undergoing cesarean sections we compared results of application of Piperacillin 4 g and Piperacillin/Tazobactam 4.5 g after cut of umbilical cord. Tazobactam/Piperacillin is a combination of a broad-spectrum penicillin and a beta-lactamase inhibitor with increased toxicity against staph. aureus, enterobacter, and other germs responsible for local and systemic infections in obstetric surgery.

Results: We did not observe any severe adverse effects. Rate of severe wound infections was 1.3 % (Tazobactam/Piperacillin) and 2 % (Piperacillin alone). The difference showed no statistic significance (p > 0.01). During postoperative course we found a higher increase of CRP (p < 0.01) in the Piperacillin group. CRP proved to be a useful objective parameter to distinguish between patients with or without postoperative infections. No differences were found in the number of leucocytes, time in hospital and other parameters.
