Double-blind trial of perioperative intravenous metronidazole prophylaxis for abdominal hysterectomy.
A double-blind trial of perioperative intravenous metronidazole treatment to prevent infections at the operative site and unexplained fever after abdominal hysterectomy was conducted in 106 patients. Metronidazole prophylaxis reduced the rate of recovery of anaerobes from vaginal swabs for several days and prolonged the high rate of vaginal carriage of enterococci and aerobic gram-negative bacilli following hysterectomy. Although the fever index, calculated from the duration of a temperature above 37.3 degrees C, was significantly lower in the metronidazole-treated group than in the placebo-treated group, the frequency of postoperative infections, the proportion of patients requiring antibiotic treatment and the average duration of hospital stay were similar in the two groups. These results do not support the reported value of perioperative metronidazole prophylaxis in patients undergoing abdominal hysterectomy.
