Paracervical Block for Intrauterine Device Placement Among Nulliparous Women: A Randomized Controlled Trial.

ABSTRACT:

Objective

To investigate whether a 20-mL buffered 1% lidocaine paracervical block decreases pain during intrauterine device (IUD) placement.

Methods

In a randomized, single-blind, placebo-controlled trial, women were assigned to receive either a 20-mL buffered 1% lidocaine paracervical block or no block before IUD placement. The primary outcome was pain with IUD placement measured on a 100-mm visual analog scale. Our sample size had 80% power (α=0.05) to detect a 20-mm difference in visual analog scale scores with a SD of 28 mm. Secondary outcomes included pain with speculum placement, paracervical block administration, tenaculum placement, 5 minutes postprocedure, and overall pain perception.

Results

From October 7, 2014, through October 26, 2017, 64 women were enrol
