Summary

The risk of pulmonary aspiration of gastric contents remains a significant risk during anesthesia, especially in pregnant women, as they may often require surgery without having observed appropriate fasting. A bedside ultrasound assessment of the status of the gastric content would be of great value for the clinician. 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

The aim of this prospective study is to provide a qualitative and quantitative description of the sonographic appearance of the gastric antrum in fasted high-risk pregnant women in the 3rd trimester. 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.
