Learning Curves of Gastric Ultrasound for Novel

• Conditions: Novel in Gastric Ultrasound; Gastric Ultrasound; Learning Curve

• Registration Number: NCT04760106
• Lead Sponsor: Mahidol University

Brief 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.
