Study summary

The purpose of this clinical trial is to evaluate the effect of an intracervical lidocaine injection versus topical lidocaine gel on the pain experienced by patients undergoing tenaculum application to the cervix during office gynecologic procedures. This study will also evaluate how satisfied women are with the method of pain control used.

The researchers hypothesize that:

  1. There is less pain perceived by patients undergoing placement of a tenaculum on the cervix when a lidocaine injection is used compared to a topical lidocaine gel.
  2. Patients are more satisfied with pain control during the overall experience of undergoing tenaculum placement on the cervix when a lidocaine injection is used compared to a topical lidocaine gel.
Read the detailed description

Subjects who have already scheduled an IUD insertion or endometrial biopsy will be asked to join this study assessing two pain control interventions at the time of tenaculum application to the cervix during office gynecologic procedures. Only healthy women ages 18 and over with an indication for endometrial biopsy or IUD placement will be recruited. The participants will be randomized to one of two arms: an intracervical lidocaine injection versus topical lidocaine gel. They will be asked to indicate their level of pain and level of satisfaction using a Visual Analog Scale. The primary outcome, pain with tenaculum placement, and the secondary outcome, satisfaction with the experience of tenaculum placement, will be compared between the study groups.

What researchers measure

Primary outcomes

  1. Tenaculum Pain

    The primary outcome was pain at the time of tenaculum placement. Patient asked to pain scale using 100mm Visual Analog Scale (0mm=no pain, 100mm=worst pain of my life) during after tenaculum placement.

    Time frame: After tenaculum placement

Secondary outcomes

  1. Intervention Pain

    Pain with the intervention (injection or gel application). Subjects are asked to complete pain scale using a 100mm Visual Analog Scale (0mm=no pain and 100mm=worst pain of my life)

    Time frame: after application of randomized intervention

  2. Tenaculum Placement Satisfaction

    Satisfaction with overall tenaculum placement procedure. Subjects asked to answer their overall satisfaction with the pain control. Subjects asked to complete 100mm Visual Analog Scale (0mm=not at all satisfied to 100mm=very satisfied)

    Time frame: After placement of the tenaculum

Limitations and caveats
There are several limitations to this study, including potential selection bias, difficulty with blinding the intervention, timing of the intervention for maximal effect, and the limitations inherent in measuring pain.

Participant flow

We conducted a randomized, single-blinded clinical trial from August 2011 to May 2012 at the Center for Women's Health at Oregon Health \& Science University (OHSU; Portland, Oregon).We recruited women aged 18 years and older who were scheduled to undergo IUD placement or endometrial biopsy.
