Bedside Ultrasound Assessment of Gastric Content and Volume

Patients undergoing gastroscopy will undergo two pre-procedure ultrasound scans of the stomach, once on arrival in the unit and on an empty stomach and a second time after consumption of a randomized amount of apple juice (0, 50, 100, 200, 300 or 400 mL). Immediately after ingestion and the second ultrasound scan, subjects will have their gastroscopy which will start by suctioning out the apple juice. Measurements of stomach fluid volume conducted by ultrasound will be compared to the actual volume removed during the gastroscopy procedure.

Treatment and study plan

Ultrasound examination followed by ingestion of Apple Juice prior to a second ultrasound procedure, followed by gastroscopic suctioning of stomach content.

Other

Ultrasound scan of the stomach followed by ingestion of 0, 50, 100, 200, 300, or 400 mL of apple juice, followed by second ultrasound scan of the stomach, followed by gastroscopic suctioning of stomach content.

Primary outcomes

Stomach volume

Time frame: 1 hour

Fluid volume in the stomach after ingestion of apple juice will be compared between measurements done with ultrasound vs direct suctioning of fluid from the stomach.
