Gastric ultrasound: A curved array, low-frequency (2-5 MHz) transducer providing a scan depth up to 30 cm will be used. Patients will be scanned in the supine position followed by right lateral decubitus (RLD) position. The sonographic appearance of the gastric antrum will be classified as Grade 0,1 or 2, signifying empty antrum, fluid detected in RLD position only and antral fluid in both supine and RLD positions, respectively, based on the appearance in both the positions. Cross-sectional area (CSA) will be calculated by using two perpendicular diameters-anteroposterior (AP) and craniocaudal (CC) and the formula for area of an ellipse:CSA = (AP × CC × π)/4

Primary outcome measure(s)
Antral cross-sectional area (CSA) — Just before surgery Cross-sectional area (CSA) will be calculated by using two perpendicular diameters-anteroposterior (AP) and craniocaudal (CC) and the formula for area of an ellipse:
CSA = (AP × CC × π)/4
