Official title: Topical Lidocaine on the Cervix and Intra-Cervical Prior to Insertion of Intrauterine Devices

Status Recruiting

Clinical Trial Summary

The hypothesis of this study is that topical cervical and intra-cervical lidocaine will decrease pain associated with the insertion of a Mirena® (levonorgestrel intrauterine device).

1. Primary Aim- Determine if topical lidocaine intra-cervically and on the cervix decreases the pain associated with insertion of a Mirena® (levonorgestrel intrauterine device).

Clinical Trial Description

There have been multiple studies performed to determine a medication that will decrease the pain associated with intrauterine device insertion. These studies have tested the use of misoprostol as well as NSAIDS to determine if these decrease the pain associated with insertion. There has also been one small, poorly performed, study that tested the use of intracervical topical lidocaine prior to IUD insertion. Misoprostol and NSAIDS were found to be non-efficacious in decreasing pain. Topical lidocaine was shown to be effective, however, secondary to this being a poorly performed study, additional studies are needed. This study is to determine if topical lidocaine does indeed decrease the pain associated with insertion of the Mirena® (levonorgestrel intrauterine device).

This is a double blinded experimental study to determine whether or not topical lidocaine gel applied to the cervix and intra-cervically decreases pain associated with insertion of the Mirena® (levonorgestrel intrauterine device). Subjects will be randomized into two groups. One group will receive 2% lidocaine gel on the cervix and intra-cervically. The other group will receive a placebo, which will consist of KY being placed on the cervix and intra-cervically. After the Mirena® (levonorgestrel intrauterine device) is inserted, each subject's pain will be assessed by using a visual analog pain scale, and their response will be recorded on the information form. This pain scale will be assessed at the time of insertion, five minutes after insertion, and ten minutes after insertion. The only other study that researched the use of topical lidocaine prior to insertion of an IUD only recorded a pain scale at the time of insertion. Additional scores will be recorded at five and ten minutes to determine if pain is reduced in those time periods. These time periods have been chosen in order that all of this information can be recorded during a normal office visit. A visual analog pain scale is the scale included which measures pain on a scale of zero to ten with zero being no pain at all and ten being the worst pain of your life. This pain scale will be a scale ranging from zero to ten with faces depicting the amount of pain involved for each score. Since there will be different physicians placing the intrauterine devices, there will be a protocol on how to perform the insertion in an attempt to make all insertions as uniform as possible. A copy of this protocol has been included. ;
