Gastric Ultrasound After Clear Fluid Intake in Diabetic and Non-Diabetic Pregnant Women
Sponsor: Ankara City Hospital Bilkent
Summary
Pulmonary aspiration of gastric contents during anesthesia is a serious perioperative complication associated with significant morbidity and mortality. Pregnant women are at increased risk of aspiration because of physiological changes such as delayed gastric emptying and increased intra-abdominal pressure. In addition, gestational diabetes mellitus (GDM) may affect gastric motility and gastric emptying. Current fasting guidelines allow the intake of clear fluids up to two hours before anesthesia. However, the effect of preoperative oral clear fluid intake on gastric volume in pregnant women with GDM remains unclear. This prospective interventional study compares gastric volume measured by gastric ultrasonography in term pregnant women with and without gestational diabetes mellitus (GDM) undergoing elective cesarean delivery. Participants receive 200 mL of oral water after baseline gastric ultrasonography. Gastric ultrasonography is performed before water intake (T1), immediately after completion of water intake (T2), and two hours after water intake immediately before anesthesia (T3) to evaluate gastric volume and gastric content. The study aims to improve the assessment of gastric volume and perioperative fasting in pregnant women, particularly those with gestational diabetes mellitus.

Oral water intake
Participants consume 200 mL of room-temperature drinking water orally immediately after the baseline gastric ultrasonography assessment (T1). Gastric ultrasonography is then repeated immediately after completion of water intake (T2) and 2 hours after water intake (T3).
