Is this trial a fit for you?

Likely a good fit

Ideal candidates are women undergoing hysterectomy for benign indications who do not have contraindications for azithromycin or cefuroxime.

Probably not a fit

Patients with allergies to cefuroxime or azithromycin, or those with certain cardiac conditions, may not benefit from this study.

What this trial studies

This study investigates whether the preoperative administration of azithromycin, in addition to the standard antibiotic cefuroxime, can decrease the incidence of post-hysterectomy infections. The primary aim is to compare the rates of infections in women undergoing hysterectomy for benign reasons who receive either azithromycin or a placebo alongside cefuroxime. Secondary outcomes include the assessment of superficial infections, urinary tract infections, postoperative fever, and potential side effects of the antibiotics. The study also explores the relationship between bacterial vaginosis, microbiome, and post-hysterectomy infections.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of infections after hysterectomy, improving patient outcomes and reducing healthcare costs.

How similar studies have gone: Other studies have shown promise in using prophylactic antibiotics to reduce postoperative infections, making this approach a potentially viable option.
