OBJECTIVE: To compare the effectiveness of intrauterine lidocaine infusion with lidocaine and intravenous tenoxicam for decreasing the pain levels associated with endometrial biopsy. METHODS: This double-blind, placebo-controlled trial was conducted at Fatih Sultan Mehmet Training and Research Hospital, Istanbul, Turkey, from May to November 2015, and comprised patients undergoing endometrial biopsy with Pipelle. Intrauterine lidocaine infusion, paracervical block with lidocaine, intravenous tenoxicam or 4ml intravenous normal saline administered prior to biopsy. The main outcome measure was pain intensity immediately afterwards and 30minutes after biopsy, determined by a visual analogue scale score. Number Cruncher Statistical System 2007 was used for statistical analyses. RESULTS: Of the 232 participants, intrauterine lidocaine infusion group had 59(25.4%) patients, 57(24.6%) were controls while paracervical block group and intravenous tenoxicam group each had 58(25%) patients. Both visual analogue scale 0 and 30 scores of the control group were significantly higher than the other three groups (p<0.05). Also, the scores of intravenous tenoxicam group were significantly higher than both intrauterine lidocaine infusion and paracervical block with lidocaine groups (p<0.05 each). CONCLUSIONS:Intravenous tenoxicam had a significantly lower effect than intrauterine lidocaine infusion and paracervical block with lidocaine during the early period after the procedure.
