Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ultrasonic display rate of stomach and duodenal bulb | 1 hour ± 0.5 hour after examination | The grade evaluation of the display effect will be determined by the total score of the gastric wall hierarchy and structure, the stomach and duodenal bulb morphology evaluation: 0-2 points for poor, 3-4 points for average, and 5-6 points for excellent. The total score of the display effect is greater than 2 points. After the end of the experiment, the sum of the number of cases with average and excellent imaging is divided by the total number of cases, and then multiplied by 100%, which is the ultrasonic display rate of the stomach and duodenal bulb. |
