Trial Outcomes & Findings for Paracervical Block Versus No Paracervical Block During IUD Insertion (NCT NCT02904915)

NCT ID: NCT02904915

Last Updated: 2018-11-07

Results Overview

The order of overall events are: insertion of speculum, assessment of pain via a visual analogue scale (VAS) (about 30 seconds after insertion of the speculum), injection of 2cc 1% lidocaine at the tenaculum site of the cervix, placement of tenaculum (about 2-3 minutes after insertion of speculum), assessment of pain via VAS (about 30 seconds after insertion of the tenaculum), injection of 3cc 1% lidocaine at the 4 and 8 o'clock position of the cervix, insert IUD (about 4-5 minutes after insertion of tenaculum), and assessment of pain via VAS (about 30 seconds after insertion of the IUD). The Faces pain VAS was used, which ranges from 0 (very happy, no hurt) to 10 (hurts as much as you can imagine).
