Bedside gastric ultrasound is used in diverse patient groups for the assessment of gastric content and volume. Using qualitative assessment, a distinction can be made between an empty stomach and one containing solid/thick fluid contents or clear fluids. In addition, quantitative assessment of gastric volume can be estimated using the cross-sectional area of the gastric antrum when clear fluid contents are present in the stomach. Small volumes ≤1.5 mL/kg1 are consistent with baseline gastric secretions, whereas higher volumes suggest patient ingestion that may increase aspiration risk. The primary objective of this study was to evaluate the relationship between gastric antral cross-sectional area as measured by ultrasound and the volume of clear fluids ingested by pregnant women.
