Trial Outcomes & Findings for Exparel Transversus Abdominis Plane Block vs Intrathecal Analgesia In Colorectal Surgery (NCT NCT02356198)

NCT ID: NCT02356198

Last Updated: 2019-03-07

Results Overview

Postoperative mean pain score for 48 hours after surgery. Pain was assessed on a 0 to 10 point visual analog scale (VAS), with 0 indicating no pain and 10 indicating severe pain. The mean pain score was summarized as the area under the curve (AUC) of the observed pain score, normalized for the total time of observation.
