Trial Outcomes & Findings for Dose Response Study of Dexamethasone in Combination With Bupivacaine 0.25% (NCT NCT01690663)

NCT ID: NCT01690663

Last Updated: 2017-05-04

Results Overview

This is defined as time from the completion of the block to the initiation of supplemental analgesia medications after hospital discharge. The patients were evaluated on different days to capture the exact end time, which was the initiation of supplemental analgesia medication. We intentionally contacted patients several times to capture the time as early as possible to minimize recall bias.

SECONDARY outcome

Timeframe: days 1, 2, and day 7

This is defined as time from the completion of the block to the time when patient is able to move his or her forearm and/or hands. The patients were evaluated on different days to capture the exact end time, which was the initiation of supplemental analgesia medication. We intentionally contacted patients several times to capture the time as early as possible to minimize recall bias.
