Brief summary

Due to the physiologically delayed gastric emptying in pregnant women, the potential risk of aspiration before cesarean delivery constitutes an important source of perioperative complications, and when it occurs, it is associated with increased maternal morbidity and/or mortality. Systematic reviews and meta-analyses have demonstrated that, compared with non-pregnant women, gastric emptying is delayed particularly during the first trimester of pregnancy, and that gastric emptying does not occur in cases who have consumed solid food within the last 8 hours and in whom labor has begun. This study aims to evaluate preoperative gastric volumes by ultrasonography in ASA II pregnant women (according to the American Society of Anesthesiologists classification, healthy parturients without complications) scheduled to undergo elective cesarean delivery under general or spinal anesthesia, based on different fasting durations for solid and liquid intake, with the type of liquid. Although previous research in pregnant populations has predominantly focused on the importance of gastric ultrasonography in the presence of gestational diabetes mellitus, this thesis study aims to generate data from the general population. The findings are expected to enable individualized preventive measures to reduce aspiration-related complications during cesarean deliveries performed under general or spinal anesthesia, thereby contributing to patient safety.

Design outcomes

Primary

Measure	Time frame	Description
Obstetric Ultrasonographic Assessment: Gastric volume	60-90 minutes before surgery	1\. Obstetric Ultrasonographic Assessment: Gastric Volume Gastric volume will be calculated by ultrasonography (with two mathematical models from the literature) before elective cesarean delivery and recorded in milliliters.
Time of last solid food / liquid intake The time of the last solid food and liquid intake by the pregnant women will be recorded in hours. Liquid type will be also recorded.	60-90 minutes before surgery	The time of the last solid food and liquid intake by the pregnant women will be recorded in hours. Liquid type will be also recorded.

Secondary

Measure	Time frame	Description
Preoperative data	60-90 minutes before surgery	In the preoperative period; the patient's age, weight (kg), body mass index (BMI, kg/m²), and gestational age (weeks + days) will be recorded.
