Sedation Regimens in GI Endoscopy

This is a noninferiority study designed to examine whether conscious sedation with midazolam alone results in efficacy and safety that is not inferior to the combination of midazolam and fentanyl. English-speaking patients ≥18 years old and ≤75 years old presenting for GI endoscopy planned with conscious sedation using midazolam and fentanyl, will be randomized 1:1 to single agent sedation with midazolam or combination sedation with midazolam and fentanyl. Participants will be blinded to the choice of sedation. Sedation quality and adverse events will be measured with a validated patient-centered measure of procedural sedation quality, the PROcedural Sedation Assessment Survey (PROSAS) \[Leffler, et al. Gastrointest Endosc. 2015;81(1):194-203\]. Endoscopic quality measures in the 2 study groups will be collected by retrospective chart review, as an additional metric to ensure the quality of the procedure is not compromised by the choice of sedation.
