The aim of this study was to compare the risk of pulmonary aspiration assessed with gastric ultrasonography in elderly patients, undergoing elective surgery.
Recently, carbohydrate loading is suggested for enhanced recovery after surgery.
Aging process often accompanies gastrointestinal dysmotility. Therefore, elderly patients might have undiagnosed gastro-esophageal reflux disease, or other gastrointestinal disorders. Moreover, because of their co-morbid underlying diseases and multi-drug effects, gastric emptying might be further delayed in the elderly patients.
This study was designated to compared the risk of pulmonary aspiration in elderly patients, with gastric ultrasound between fasting group and carbohydrate loading group.

| Incidence of risk of pulmonary aspiration assessed by gastric ultrasound defined by Perlas grade 2 | Incidence of Perlas grade 2. Clear fluid is detected in gastric antrum by gastric antral ultrasound on both supine and right lateral decubitus position. Perlas grade 2: fluid appears in both supine and right lateral decubitus positions Perlas grade 1: fluid is detected only in right decubitus position Perlas grade 0: fluid is not detected in both supine and right lateral decubitus positions. | 2 hours after intake of last allowable carbohydrate drink time |
| Measure | Description | Time Frame |
|---|---|---|
| cross-sectional area of gastric antrum in supine position | cross sectional area of gastric antrum is calculated by using the following formula: cross-sectional area = long axis x short axis x 3.14 /4 | 2 hours after intake of last allowable carbohydrate drink time |
| cross-sectional area of gastric antrum in right decubitus position |
