An Evaluation of the Paracervical Block for Pain Control in First Trimester Surgical Abortion
In Brief
A Phase 4 clinical trial evaluating Paracervical Block and Sham Paracervical Block for Legal Abortion With Complication and Pain. Completed, enrolled 121 participants across 1 site.
Detailed Summary
Many woman undergoing a surgical abortion receive a paracervical nerve block for pain reduction, in which lidocaine (a numbing medication) is injected around the cervix. These injections numb the cervix and possibly the lower part of the uterus. However, the injection can be uncomfortable and it is not well known whether it is effective in reducing pain. The purpose of this study is to determine the level of pain women experience with a surgical abortion and the effect that paracervical block might have on that pain.

Interventions
Subject receives 20 mL paracervical block with 18 mL of 1% Lidocaine solution buffered with 2 mL 8.4% sodium bicarbonate for pain control.
In the non-intervention group, the surgeon performs a sham PCB during which 2 mL buffered lidocaine solution are injected at the tenaculum site, after which a capped needle gently simulates the standard PCB procedure.
