Summary

Various studies have shown that gastric sonography can reliably provide information on both qualitative (nature of content) and quantitative (volume) aspects of gastric content. A recent study has suggested that a minimum of 33 scans is needed to achieve a 95% success rate in the qualitative assessment of gastric ultrasound. However, as the risk and severity of aspiration are also influenced by gastric volume, further study concerning quantitative assessment is warranted.

Detailed description

This study are conducted to affirm the feasibility of ultrasound for the qualitative assessment of gastric content, and determine the reliability of this novel tool in gastric volume measurements when performed by novice gastric sonographers. Two novels in gastric ultrasound learn from online materials, including educational videos and picture library through www.gastricultrasound.org and www.usra.ca. 1-hour lecture with discussion and 1-hour interactive hands-on with expert in gastric ultrasound. Then the novels were tested for the accuracy and reliability of their skills from 50 volunteers gastric ultrasound assessment.

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	gastric ultrasound	For the qualitative assessment, every participant was scanned once by both examiners. Each scan session lasted no longer than 5 minutes to mitigate the confounding effect of gastric emptying time. For the quantitative assessment, the participants were put in a right lateral decubitus position and the antral cross-sectional area (CSA) is measured in the sagittal plane.
