Cervical Lidocaine for Intrauterine Device Insertion Pain

Randomized Controlled Trial of Cervical Lidocaine for Intrauterine Device Insertion Pain

The aim of this study is to evaluate intracervical lidocaine gel as a means to decrease pain associated with intrauterine device (IUD) insertion. They will be randomized to either placebo (inert water based lubricating gel) or 2% lidocaine gel to be placed intracervically via angio-catheter just before intrauterine device insertion. Anticipated pain scores will be assessed using a visual analog scale prior to insertion. Using the same pain scale, patients will again be asked at the end of the procedure to rate their pain.

Double blind randomized controlled trial.

Primary outcome: Pain reported on Visual Analog Scale (VAS) Intervention: 2% lidocaine gel at the tenaculum site and intracervical prior to intrauterine device placement
