Trial Outcomes & Findings for A Comparison of Tumescence in Breast Reduction Surgery (NCT NCT01602692)

NCT ID: NCT01602692

Last Updated: 2020-10-05

Results Overview

Aim 1 is to determine the effect of dilute lidocaine in tumescent solution on post-operative pain following breast reduction surgery. The data points that will be statistically compared will be pain scores determined via a validated pain survey (pain levels on a scale of 0-10 where 10 is the worst pain) and the amount of narcotic medication administered (in Postanesthesia Care Unit (PACU), phase 2 and up to 24 hours post-op) determined from responses to survey questions and by reviewing the medical record.
