[Clinical study of tazobactam/piperacillin in obstetrics and gynecological infections].

A clinical study was carried out to investigate clinical efficacy and safety of tazobactam/piperacillin (TAZ/PIPC), a newly developed antibiotic agent for injections. The obtained results are as follows: 1. In 10 patients with obstetrics and gynecological infections (7 patients with endometrial infections, one patient with pelvic peritonitis, one patient with ovarian abscess and one patient with Bartholins's abscess) intravenous drip infusion of TAZ/PIPC, 5.0 g/day, was administered for 5 to 10 days. The total doses were 2550 g/body. 2. Clinical efficacy was evaluated in the above cases. As a result, an excellent result was obtained in one patient and good efficacies in 9 patients. The efficacy rate was 100% (10/10). Concerning the clinical bacteriological effect, eradication ratio was 83.3% (5/6). Concerning the bacteriological effect against 11 strains of clinical isolates, 4 strains were eradicated, 6 strains were replaced and one strain was unchanged. 3. Neither subjective/objective side effects nor abnormal laboratory test results were observed upon administration of TAZ/PIPC. These results suggested the usefulness of tazobactam/piperacillin in obstetrics and gynecological infections.
