Design outcomes

Primary

Measure	Time frame
1 Antral cross sectional area CSA 2 The gastric volume (GV) will be calculatedTimepoint: gastric volume assessment at 0 hours, when patient is nil per orally and 2 hours after ingestion of carbohydrate drink	—

Secondary

Measure	Time frame
? Aspiration after Ryle?s tube insertion at the time of surgery to assess gastric aspirate pH as pH decreases by 2.5, increases the risk of gastric aspiration 2 Incidence and severity recorded during the first 24 hours post-surgery using the simplified PONV Impact scale where the nausea ordinal response will be used to quantify nausea intensity or impact on the patient 3 All patients will complete the QoR-15 Questionnaire twice, on the morning of the surgery, in the preoperative waiting area, and 24 h following the surgeryTimepoint: 24 hours following the surgery	—
