This prospective observational study aimed to evaluate the effect of preoperative fasting duration on gastric volume and antral visibility in pregnant women undergoing elective cesarean section. Patients were divided into two groups according to fasting duration (6-8 hours and 8-10 hours), and preoperative gastric ultrasonography was performed to assess antral cross-sectional area and gastric volume.
Additionally, the study investigated the relationship between gastric ultrasound findings and postoperative complications such as nausea and vomiting. The influence of demographic and clinical variables, including age, body mass index, ASA score, and fetal characteristics, on gastric volume was also evaluated.
