BackgroundPotential pain with IUD insertion is a concern for women. Studies have found that systemic and local cervical therapies do not reduce pain scores. Since intrauterine infusion of lidocaine may reduce pain with endometrial aspiration, in this pilot study, we tested whether such infusion through an inexpensive endometrial aspirator could reduce IUD insertion pain scores with IUD insertion.Study DesignIn this randomized, double-blinded, placebo control pilot study of 40 women undergoing IUD insertion, pain scores of women receiving 1.2 mL 2% lidocaine versus normal saline (1:1) infused 3 min prior to IUD insertion were measured using a 0-9-point scale.ResultsPain at tenaculum placement was similar between groups. There was no difference in mean pain scores during IUD insertion of women infused with lidocaine (2.95) versus normal saline (3.75), p=.37. Considerable variation in pain scores was noted; 46% of subjects had pain scores ≤2 while 33% had pain scores ≥5.ConclusionUse of 2% lidocaine administered through an endometrial aspirator did not significantly reduce IUD insertion pain scores in this pilot study.Copyright © 2013 Elsevier Inc.
