Paracervical Block Before Intrauterine Device (IUD) Insertion

This study has been completed.

Jessica Kiley, Northwestern University Identifier:
First received: September 21, 2010
Last updated: May 2, 2013
Last verified: May 2013
The purpose of this study is to evaluate if a paracervical block containing 1% lidocaine administered prior to IUD insertion reduces insertion pain. The hypothesis is that women receiving paracervical analgesia will experience less pain during IUD insertion than those who do not receive such analgesia.

Condition Intervention
Pain Control for Intrauterine Device Insertions Drug: Lidocaine

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Primary Outcome Measures:
  • Median Visual Analogue Score Measuring Pain [ Time Frame: 1) Speculum placement 2) Tenaculum placement 3) Paracervical block administration(if subject is in this arm) 4) IUD insertion 5) Five minutes post procedure ]

    We asked participants to report their pain score on visual analogue scale (0mm=no pain and 100mm=worse pain possible) at the following time points:

    1. Speculum placement
    2. Tenaculum placement
    3. Paracervical block administration(if subject is in this arm)
    4. IUD insertion
    5. Five minutes post procedure
