An observational study in Ultrasound Evaluation of Gastric Contents, sponsored by The Second Affiliated Hospital of Chongqing Medical University. Completed at 1 site in China. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-08-14.
Sponsored by The Second Affiliated Hospital of Chongqing Medical University · Observational
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.
The Second Affiliated Hospital of Chongqing Medical University is the lead sponsor of 98 studies on the registry; 29 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Outpatients undergoing painless electronic gastroscopy were fasted for 8 hours in acccordance with gastroscopy guidelines
Exclusion Criteria:
The cross-sectional area of the antrum (CSA)
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
Time frame: Before the painless electronic gastroscopy
Predicted volume
Predicted volume calculated by CSA
Time frame: Before the painless electronic gastroscopy
Observed volume
All gastric fluid was thoroughly suctioned through an endoscope side port, measured to the nearest mL and recorded
Time frame: Before the painless electronic gastroscopy
