A Dual Channel Supraglottic Airway Device (LMA Gastro) for Oxygenation in Patients Undergoing ERCP

This clinical trial compares the effect of LMA Gastro, a dual channel supraglottic airway (SGA) device, to oxygenation with standard nasal cannula for endoscopic retrograde cholangiopancreatography (ERCP). An ERCP is a combination of imaging scans and endoscopy that helps doctors diagnose and treat conditions of the pancreas and bile ducts that requires general anesthesia or procedural sedation. Anesthesiologists often use SGAs or nasal cannulas to help patients breathe while they are asleep during procedures. An SGA consists of an airway tube that connects to a mask, which is inserted through the mouth and placed at the back of the throat to keep the airway open while patients are under anesthesia or sedation. The nasal cannula is a device that fits in a patient's nostrils and delivers oxygen through a small, flexible tube while they are under anesthesia or sedation. The goal of this trial is to compare the effects of the LMA Gastro to nasal cannula when used to deliver oxygen to patients while they are asleep during their ERCP procedure.
