Lost IUD Clinical Trial
Objective: To evaluate the efficacy of intrauterine lidocaine instillation in reducing
patient discomfort during the removal of a "lost" intrauterine device (IUD).
Methods: This double-blinded, randomized, placebo-controlled trial included 68 women who
underwent removal procedure for a "lost" IUD. Thirty-four women were allocated to the
lidocaine group and 34 to the saline group. The main outcome measure was the intensity of
pain during, immediately after, and 20 minutes after the procedure, assessed by a visual
analog scale. Statistical analysis was performed using Friedman's test with Bonferroni
correction, Student's t test, and 2.
