Trial Outcomes & Findings for Pain Outcomes of Non-opioid vs. Opioid Analgesia for Kidney Stone Surgery. (NCT NCT03584373)

NCT ID: NCT03584373

Last Updated: 2023-12-18

Results Overview

The patient will be administered a survey and asked to rate satisfaction with pain relief since the time of surgery and being on the assigned medication. Scoring will be on an 11-point ordinal numeric rating scale, with 0 being not satisfied with pain relief, and 10 being well-satisfied. Higher scores are indicative of greater satisfaction with pain relief

Participant Flow

Patients scheduled for surgery between July 2018 and May 2021 were consented and enrolled into the study.

A total of 119 patients were consented and enrolled into the study. Of the 119 patients, 14 patients screen failed (did not meet inclusion/exclusion criteria) and were not randomized into the study. Accordingly, 105 patients were randomized into the two arms/groups for this study.
