Bedside Ultrasound Assessment of Gastric Content and Volume

Not Applicable

Completed

• Conditions: Gastroscopy
• Interventions: Other: Ultrasound examination followed by ingestion of Apple Juice prior to a second ultrasound procedure, followed by gastroscopic suctioning of stomach content.

• Registration Number: NCT01151228
• Lead Sponsor: University Health Network, Toronto

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
400 mL	Ultrasound examination followed by ingestion of Apple Juice prior to a second ultrasound procedure, followed by gastroscopic suctioning of stomach content.	Patients will ingest 400 mL apple juice prior to the second ultrasound.
Zero volume	Ultrasound examination followed by ingestion of Apple Juice prior to a second ultrasound procedure, followed by gastroscopic suctioning of stomach content.	Patients will not ingest any apple juice prior to the second ultrasound.
50 mL	Ultrasound examination followed by ingestion of Apple Juice prior to a second ultrasound procedure, followed by gastroscopic suctioning of stomach content.	Patients will ingest 50 mL apple juice prior to the second ultrasound.
100 mL	Ultrasound examination followed by ingestion of Apple Juice prior to a second ultrasound procedure, followed by gastroscopic suctioning of stomach content.	Patients will ingest 100 mL apple juice prior to the second ultrasound.
200 mL	Ultrasound examination followed by ingestion of Apple Juice prior to a second ultrasound procedure, followed by gastroscopic suctioning of stomach content.	Patients will ingest 100 mL apple juice prior to the second ultrasound.
300 mL	Ultrasound examination followed by ingestion of Apple Juice prior to a second ultrasound procedure, followed by gastroscopic suctioning of stomach content.	Patients will ingest 300 mL apple juice prior to the second ultrasound.

Primary Outcome Measures

Name	Time	Method
Stomach volume	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.
