The aim of this study was to validate 4 methods of estimating stomach volume from sonographic images for monitoring gastric volume changes in preterm infants. Twenty four preterm infants born <34 weeks gestation were recruited. Ultrasound images of the gastric antrum and stomach were recorded at four time points during an intra‐gastric tube feed. Antral cross‐sectional area (ACSA) and three estimates of stomach volume were validated for intra‐ and inter‐rater agreement. Changes in ACSA and stomach volume were compared to the feed volume delivered. Estimating stomach volume as a spheroid best matched the delivered feed volume, and reliably estimated the volume. There was no relationship between ACSA and feed volume. Serial sonographic imaging of the stomach provides a reliable, accurate and well‐tolerated method of monitoring gastric emptying in preterm infants.
