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.
