An observational study in Respiratory Aspiration of Gastric Contents, sponsored by University of Florida. Completed at 1 site in United States. Open to participants aged 18 Years to 99 Years. Per ClinicalTrials.gov, last updated 2026-09-22.
Sponsored by University of Florida · Observational
The purpose of this research study is to look at the effectiveness of current anesthesia guidelines regarding food and drink prior to surgery in patients who are likely to have food and drink remain in their stomach longer than might ordinarily be expected.
Examine the utility of ultrasound examination of the stomach in estimating aspiration risk in patient populations whose aspiration risk is currently poorly understood. Evaluate the applicability of current pre-surgical fasting guidelines in the same patient populations whose aspiration risk is poorly understood.
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.
