title: [Fundamental and clinical studies of ceftriaxone in the field of obstetrics and gynecology].
abstract: The study was done to evaluate the usefulness of ceftriaxone (Ro 13-9904, CTRX) injection for the treatment of infections in the field of obstetrics and gynecology. Fundamental and clinical studies were made and following results were obtained. When 1 g of CTRX is administered by intravenous single shot, the concentrations in various tissues of female genital organs were as follows: 40 micrograms/g in oviduct, 30 micrograms/g in ovary, 23 micrograms/g and 32 micrograms/g in corpus uteri and cervix uteri, respectively, at 2 hours 20 minutes after single shot. As for the transfer to the exudate in the pelvic dead space, the peak concentrations were 66-69 micrograms/ml after 4-5 hours. In the clinical studies, CTRX was given to 20 cases with female genital organ infections and others. As for the clinical effects, responses were excellent in 2 cases, good in 18 cases among 20 cases in total. The efficacy rate was 100%. As for the clinical effects on causative bacteria, the efficacy rates were 100% for single infections due to Gram-positive bacteria (6/6), due to Gram-negative bacteria (1/1), for mixed infection (3/3). Side effect was observed in 1 case with diarrhea. CTRX showed a satisfactory clinical efficacy and a potent bacteriological effect in treatment of the infections in the field of obstetrics and gynecology, and it has been concluded that CTRX will be a useful addition to the antibiotics for the therapy of these infections.
