Wound infections and systemic antibiotic prophylaxis in gynecologic surgery. A review

The gynecologic literature was reviewed and yielded 11 well-designed and well-conducted studies since 1960 involving the use of systemic prophylactic antibiotics. Five had significant results that support using prophylactic antibiotics in vaginal hysterectomy while three supported prophylaxis in cesarean sections. A cephalosporin agent is effective as a prophylactic agent and should be administered 2 hours before surgery by the intravenous route and discontinued 24-72 hours after surgery. A change in the bacteriologic flora of the cervical cuff occurs after surgery with an increase in E. coli and enterococci and a decrease in coagulose negative staphylococci and steptococci. Future studies should be randomized, prospective, and performed in a double-blind manner with antibiotics begun preoperatively. Special attention should be given to bacteriologic techniques, especially the search for anaerobic pathogens.
