Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Preoperative gastric ultrasonography is a newly developed tool used to evaluate gastric content and volume in assessing perioperative aspiration risk and guide anaesthetic management. And then build up effective clinical predictive models for identification of full stomach, which can predict the high aspiration risk.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Aspiration of gastric contents can be a serious anesthetic related complication. Preoperative fasting was a common practice to decrease perioperative aspiration risk. However，one of most important prescription of enhanced recovery after surgery protocols is the reduction of preoperative fasting time in opposition to the traditional recommendation of overnight fast. Gastric antral sonography prior to anesthesia may have a role in identifying patients at risk of aspiration. The aim of this study is to construct models using deep learning for identification of full stomach, which can predict the aspiration risk.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

experiment

The data will be collected in two phases. Firstly, after a fasting period of eight hours, the participants received ultrasound scan by expert doctor with the objective of measuring the fasting gastric antrum area in supine and right lateral decubitus(RLD)position(phase 1).Then the expert made the grading according to the ultrasound image.

In phase 2, the participant will ingest 0 to 400ml of the study drink described below randomly. The individual will be immediately positioned in the supine position and another ultrasound scan will be carried out. Again in the RLD position.
