Brief Summary

The purpose of this study is to evaluate the hemodynamics and adverse event profile in comparison between two treatment arms, one using an admixture of propofol and etomidate at a ratio by volume of 25%/75% (P2E7), and one using an admixture of propofol and etomidate at a ratio by volume of 75%/25% (P7E2), for anesthesia during endoscopic procedures at the Clements University Hospital (CUH) endoscopy lab (Endo).

Masking Details
Blinding plan: Either the investigational drug service with the CUH central pharmacy will prepare the admixture syringes or a separate anesthesia staff not involved in subject's case will prepare admixture syringes thus preventing any case personnel involved with subject's case or subject from knowing which admixture is present within syringes for subject's case.
