Advisability of using early generation Cephalosporines for prevention and treatment of postpartum infection

Cover Page


Introduction: the following research investigates an availability of a long-lime treatment of postpartum infection by using of Cephalozolin (the Cephalosporine of generation I).

Matherials and Methods. Lochia samples were obtained from the uterine cavities of 21 puerperal women who did not receive drug after delivery and were cultured for the identification and the determination of the susceptibilities of the clinical isolates to Cephalozolin. The concentrations of Cephalozolin in the supernatants were measured by highperformance liquid chromatography.

Results. We determined the sensivity of the most clinically important bacteria to Cephazoline and its penetration rate to the uterine cavity. We found out the following bacteria which are sensible to Cephazoline – S. agalactiae, E. coli, K. pneumoniae, E. aerogenes. A low rate of Cephazoline ≤ 0,78 mg/ml was inhibited the growth of mentioned above bacteria. Cephazoline is also active as for S. aureus – MIC90 and was equal 3.13 mg/ml. In 3 hours after the injection of 1.0 gr of Cephazoline there was a maximum concentration in a venous blood – 1.63 mg/ml. The concentration of Cephazoline in lochia was rising gradually and it maximum in the uterus cavity in 5 hours was 1.26 mg/ml, and then its slowly went down.

Conclusions. The mention above results let us suggest that Cephazoline is penetrates actively to lochia and its still has a good antibacterial effect. Cephazoline is still a treatment of choice as for prevention and a treatment of postpartum surgical site infections by a sensitive microorganism.
