Trial Summary

What is the purpose of this trial?

The objective of this study is to to determine whether 1% lidocaine paracervical block reduces pain during endometrial biopsy in comparison to no intervention. The proposed study is a double-blind randomized controlled trial (RCT). Each participant will be randomly assigned to one of two arms: 1. intervention (paracervical block - 10 mL 1% lidocaine with epinephrine) 2. control (gently tapping the cervicovaginal junction with a capped needle) The primary outcome will be a global pain score, which will be patient-reported by the 100 mm Visual Analogue Scale (VAS) following the procedure.
