Application of Portable Ultrasonic Evaluation of Gastric Contents in Painless Gastroscopy

August 13, 2024 updated by: The Second Affiliated Hospital of Chongqing Medical University
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

Outcome Measure
Measure Description
Time Frame
The cross-sectional area of the antrum (CSA)
Time Frame: 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
Before the painless electronic gastroscopy
Predicted volume
Time Frame: Before the painless electronic gastroscopy
Predicted volume calculated by CSA
Before the painless electronic gastroscopy
Observed volume
Time Frame: Before the painless electronic gastroscopy
All gastric fluid was thoroughly suctioned through an endoscope side port, measured to the nearest mL and recorded
Before the painless electronic gastroscopy
