Perlas et al developed an improved equation for estimating gastric volume based on gastric ultrasound measurements. The authors are from the University of Toronto and Toronto Western Hospital.
(1) age of the patient in years
(2) cross-sectional area of the gastric antrum in square cm with the patient in a right lateral decubitus position
predicted gastric volume in mL =
= (14.6 * (cross sectional area)) - (1.28 * (age)) + 27
