What this Trial Is About
Delayed gastric emptying increases the risk of pulmonary aspiration during general anesthesia. Diabetes mellitus and poor long-term glycemic control have been associated with impaired gastric motility. Hemoglobin A1c (HbA1c) is a marker of long-term glycemic control; however, its relationship with gastric emptying in surgical patients is not fully understood. This prospective observational study aims to evaluate the association between HbA1c levels and gastric emptying using preoperative bedside gastric ultrasonography. Adult patients scheduled for elective surgery under general anesthesia will undergo gastric ultrasound examination after standard fasting. Gastric antral cross-sectional area and estimated gastric volume will be assessed and compared according to HbA1c levels. The findings of this study may help improve preoperative risk stratification for aspiration and support individualized anesthetic management in patients with impaired glycemic control.
