Gastroparesis
Conditions
Brief summary
Investigators assess the gastric contents by ultrasonography in fasted patients undergoing cholecystectomy.
Detailed description
Investigators evaluate the gastric volume through cross sectional area and amount of clear fluid using Perlas grade by ultrasound in the supine and right lateral position of fasted patients undergoing cholecystectomy. Full stomach is regarded if solid gastric contents are detected or clear fluid is more than 1.5 ml/kg. The frequency of full stomach will be analyzed.
Interventions
Ultrasound assessment of gastric content is performed in fasted patient undergoing cholecystectomy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of full stomach | Before the induction of anesthesia | The incidence of full stomach is assessed by using ultrasonography. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cross sectional area of the stomach | Before the induction of anesthesia | The cross sectional area of the stomach is assessed by using ultrasonography in the supine and right lateral positions. |
| Volume of stomach | Before the induction of anesthesia | The volume of stomach is assessed using the following formula; volume of stomach (mL) = 27.0 + 14.6 x cross-sectional area (right lateral position) - 1.28 x age. |
| Type of gastric contents | Before the induction of anesthesia | The type of gastric contents is assessed using ultrasonography. |
