Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This prospective observational study aimed to (1) qualitatively and quantitatively describe the sonographic appearance of the gastric antrum in fasted high-risk pregnant women during the third trimester and (2) evaluate the relationship between demographic and clinical variables and the gastric antral cross-sectional area (CSA).
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators expect that the information obtained from the systematic ultrasonographic qualitative/quantitative assessment of the gastric content may help anesthesiologist to better assess aspiration risk and guide anesthetic and airway management, particularly in pregnant women scheduled for elective Cesarean delivery after standard preoperative fasting guidelines.
