Trial Outcomes & Findings for Improving Post-Operative Pain and Recovery in Gynecologic Surgery (NCT NCT04175509)

NCT ID: NCT04175509

Last Updated: 2022-01-20

Results Overview

Post-operative pain control using a standardized pain scale from 0 (no pain) to 10 (worse pain) measured every 4 hours for the 24 hours, or discharge, whichever comes first. Time points were averaged for each participate and reported as a single value.
