OBJECTIVE: To evaluate the efficacy and safety of topical anaesthesia in reducing pain and incidence of vasovagal reactions during diagnostic hysteroscopy with endometrial biopsy in postmenopausal women. DESIGN: Randomised placebo-controlled double-blind study. SETTING:University hospital. PARTICIPANTS: Eighty postmenopausal women undergoing diagnostic hysteroscopy and endometrial biopsy. INTERVENTIONS: Two millilitres of 2% mepivacaine or saline solution were injected transcervically into the uterine cavity before performing the procedures. MAIN OUTCOME MEASURES: Evaluation of pain reduction on a visual analogue scale and continuous monitoring of heart rate and blood pressure. RESULTS: The use of the anaesthetic significantly reduced the pain experienced at hysteroscopy and endometrial biopsy. The occurrence of vasovagal reactions was significantly lower in the anaesthetised group. CONCLUSIONS:Topical anaesthesia attenuated pain and effectively prevented the occurrence of vasovagal reactions during hysteroscopy and endometrial biopsy in postmenopausal women.
