Application of Portable Ultrasonic Evaluation of Gastric Contents in Painless Gastroscopy

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.

Treatment and study plan

Primary outcomes

  1. 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

  2. Predicted volume

    Time frame: Before the painless electronic gastroscopy

    Predicted volume calculated by CSA

  3. 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
