- Primary Outcome Measures
Name Time Method To compare the incidence of gastric insufflation (air leak into the stomach) between two techniques.Timepoint: At baseline and immediately after endotracheal intubation.
- Secondary Outcome Measures
Name Time Method 1. To compare change in gastric volume as calculated by ultrasound assessment of antral cross-sectional area (CSA) between two techniques. <br/ ><br>2. To compare changes in the blood gas parameters (pH, PaO2 and PaCO2) at predefined time points [before surgery (T1), following pre-oxygenation and before induction of anaesthesia (T2) and after intubation before initiating mechanical ventilation (T3)] between two techniques. <br/ ><br>3.To compare symptoms suggestive of gastric insufflation between two techniques. <br/ ><br>4.To compare peristaltic contractions of gastric antrum between two techniques. <br/ ><br>5. To find out the risk factor for gastric insufflation. <br/ ><br>Timepoint: First 24 hours postoperative period
