Application of Portable Ultrasonic Evaluation of Gastric Contents in Painless Gastroscopy

Completed

• Conditions: Ultrasound Evaluation of Gastric Contents

• Registration Number: NCT05469633
• Lead Sponsor: The Second Affiliated Hospital of Chongqing Medical University

Brief Summary

To explore the correlation between gastric ultrasound evaluation and gastroscopic direct vision evaluation of gastric contents, so as to more accurately use gastric ultrasound to evaluate the gastric contents of patients undergoing painless electronic gastroscopy in the outpatient department, so as to develop an individual painless diagnosis and treatment strategy to reduce the risk of lung aspiration.

Primary Outcome Measures

Name	Time	Method
Predicted volume	Before the painless electronic gastroscopy	Predicted volume calculated by CSA
Observed volume	Before the painless electronic gastroscopy	All gastric fluid was thoroughly suctioned through an endoscope side port, measured to the nearest mL and recorded
The cross-sectional area of the antrum (CSA)	Before the painless electronic gastroscopy	The maximum anteroposterior diameter (recorded as D1) and maximum craniocaudal diameter (recorded as D2) between the gastric antrum serosal surfaces were measured perpendicularly to each other.CSA(cm2) = (π × D1 × D2) / 4
