Antibiotics Prophylaxis for Operative Hysteroscopy: A Multicenter Randomized Controlled Clinical Study.

To evaluate the incidence of infectious complications and effect of prophylactic antibiotic administration during operative hysteroscopic procedures.A multicentric randomized controlled trial was conducted between January 2012 and December 2013. Women (n = 180) affected by endometrial hyperplasia, myomas, or endometrial polyps undergoing operative hysteroscopy were randomized to receive cefazolin 2 g intravenously 30 minutes prior to the procedure (n = 91) and no treatment (n = 89).No statistical difference in terms of postoperative fever (2.4% vs 2.3%, P = .99), endometritis (0% vs 0%), pain (6.0% vs 10.4%, P = .40), cervicitis-vaginitis (0% vs 0%), pelvic abscess (0% vs 0%), pelvic inflammatory disease (0% vs 0%), and bleeding (0% vs 0%) was noticed. No statistical difference in terms of side effects attributable to antibiotic prophylaxis such as allergy (0% vs 4.8%, P = .12), nausea (10.7% vs 17.4%, P = .27), vomiting (3.6% vs 4.6%, P = .99), diarrhea (4.8% vs 5.4%, P = .99), cephalea (9.5% vs 3.5%, P = .13), dizziness (4.8% vs 2.3%, P = .44), and meteorism (5.4% vs 3.4%, P = .99) was noticed.The results of the current study support the recommendation not to prescribe routine antibiotic prophylaxis prior to operative hysteroscopy.
