Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Evaluate the residual gastric contents in patients presenting for upper GI endoscopy procedures who have adhered to pre-operative fasting guidelines. Evaluate the residual gastric contents in patients presenting for upper GI endoscopy procedures who have not adhered to pre-operative fasting guidelines. Only patients expected to have an oral-gastric tube placed during upper GI endoscopy procedure will be included. Both groups will be evaluated to learn if their residual gastric contents conform to currently-accepted standards for low aspiration risk.
