[Basic and clinical studies of ceftriaxone in the field of obstetrics and gynecology].

Ceftriaxone (Ro 13-9904, CTRX), a new cephalosporin antibiotic, was basically and clinically studied in the field of obstetrics and gynecology. The following results were obtained. The pelvic dead space exudate and serum levels of CTRX were measured in patients with radical hysterectomy with pelvic lymphadenectomy for uterine cervical cancer after the intravenous injection of 1 g. Immediately after the injection, the serum level increased to 146 micrograms/ml on average and thereafter declined rapidly. The pelvic dead space exudate level attained the peak of 88 micrograms/ml after 4 hours and thereafter declined gradually but was 74 micrograms/ml even at 8 hours after the injection. A total of 13 cases comprising 2 with intrauterine infection, 5 with pelveoperitonitis, 4 with adnexitis and 2 with external genital organ infection were intravenously treated with CTRX at a dose of 1 g twice daily for 3-7 days. The clinical results were good in 12 cases and unknown in 1 case. Eruption was noted in 1 case.
