- Brief Summary
Aspiration of gastric content is a serious perioperative event associated with morbidity and mortality. Patients with a “full stomach†are at increased aspiration risk when sedation or general anaesthesia impair their lower oesophageal sphincter tone and protective airway reflexes. Several studies have used bedside ultrasound to evaluate GRV to assess perioperative aspiration risk and guide anaesthetic management. The purpose of this study is to examine whether the use of bedside ultrasound and Perlas’ formula by trained anaesthesiologists can accurately measure gastric volume in patients undergoing elective surgery who have consumed various quantities of different types of liquids.

- Primary Outcome Measures
Name Time Method To measure the accuracy of measurement of gastric volume using USG (and Perlas’ formula) 5 minutes after consumption of a fixed quantity of water or milk (to be decided by randomization)
- Secondary Outcome Measures
Name Time Method 1.To examine whether type of fluid – clear (water) or particulate (milk) affects the agreement 5 minutes after consumption of a fixed quantity of water or milk (to be decided by randomization) To look at inter-rater agreement in GRV measurements 5 minutes after consumption of a fixed quantity of water or milk (to be decided by randomization) To examine whether volume of fluid (100 versus 200 ml) affects the accuracy of measurement 5 minutes after consumption of a fixed quantity of water or milk (to be decided by randomization)
