Trial Outcomes & Findings for Decreasing Postoperative Pain Following Endometrial Ablation (NCT NCT02660918)

NCT ID: NCT02660918

Last Updated: 2019-08-28

Results Overview

Pain will be assessed using a 10 point visual analog scale. On the scale 0 represented no pain and 10 represented the highest pain level. Eligibility for analgesia was available for patients who reported pain higher than 5 out of 10 on the scale. Pain levels were assessed by trained nursing staff blinded to the study. Lower numbers on the 10 point scale represented a positive outcome. Patients
