Perioperative aspiration is particularly concerning in pregnant women due to anatomical changes. To mitigate this risk, pre-anesthetic fasting is recommended, with varying guidelines. Gastric ultrasound can non-invasively assess stomach contents, and mathematical models help estimate stomach volumes using the gastric antral cross-sectional area (CSA). This study aims to compare CSA and estimated gastric volumes through ultrasound in fasting diabetic and non-diabetic pregnant women scheduled for cesarean section, as diabetes may affect stomach fullness. Additionally, it will investigate the relation between demographic and clinical variables and CSA values. This research can shed light on diabetes' influence on aspiration risk in pregnancy and evaluate fasting guidelines, underscoring the significance of gastric ultrasound.
