[Local prevention of infection with metronidazole before vaginal hysterectomy--comparative effect compared with...

A prospective clinical trial was designed to examine the influence of a local intravaginal application of metronidazole on postoperative infectious morbidity in 114 women undergoing vaginal hysterectomy. On the evening before vaginal hysterectomy, 51 patients received a vaginal suppository of metronidazole (500 mg). These patients were compared with a group of 63 patients who were given a single-shot prophylaxis with 1,500 mg cefuroxime intravenously. With regard to febrile morbidity, urinary tract infection and pelvic infection there was no significant difference in the two treatment groups. There was no statistically significant difference in the postoperative duration of hospital stay and additional antibiotic therapy between the two groups either. We did not see serious infections in our examination. Our results suggest that a local single-dose application of metronidazole in vaginal hysterectomy might have the same efficacy on postoperative infectious morbidity than a systemic antibiotic prophylaxis and that it can reduce antibiotic costs.
