Does the use of Bispecteral Index reduce the oxidative stress in Endoscopic Retrograde Pancreoticocolangiography?

Background: Endoscopic Retrograde Pancreoticocolangiography (ERCP) is performed for resolving cholestasis by sphincterotomy and/or stone extraction and is done with deep sedation or general anesthesia. Aim: Our aim was to evaluate the effects of the depth of anesthesia on oxidative stress provided via Bispecteral Index (BIS) monitorisation during the ERCP procedure by analyzing the biochemical parameters. And also was the effects of anesthesia depth on propofol consumption and postoperative sedation status.
