Risk Factors and Outcomes of Reversal Agent Use in Moderate Sedation During Endoscopy and Colonoscopy.

Background: Moderate sedation has been standard for noninvasive gastrointestinal procedures for decades yet there are limited data on reversal agent use and outcomes associated with need for reversal of sedation.

Aim: To determine prevalence and clinical significance of reversal agent use during endoscopies and colonoscopies.

Methods: Individuals with adverse events requiring naloxone and/or flumazenil during endoscopy or colonoscopy from 2008 to 2013 were identified.
