Ultrasound Evaluation of Gastric Contents
Conditions
Keywords
gastric ultrasound, gastric contents, painless electronic gastroscope
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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 |
| 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 |
