Primary

Measure	Time frame
preoperative gastric volume measured by ultrasound	—

Secondary

Measure	Time frame
grading of gastric content as assessed by ultrasound ? Grade 0 (empty stomach): If no content is visualized in the lateral decubitus position, the stomach is empty. ? Grade 1 (low risk): If fluid content calculated to be less than 1.5 mL/kg, the patient is is at low risk for aspiration. ?
