HbA1c and stomach emptying before anesthesia measured by gastric ultrasound
Official title: Evaluation of the Effect of Hemoglobin A1c Levels on Gastric Emptying Assessed by Gastric Ultrasound
Run by Kutahya Health Sciences University · NCT07375680 · Data updated 2026-11-12
This study will test whether adults having elective surgery with higher HbA1c have slower stomach emptying before general anesthesia.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18–70 scheduled for elective surgery under general anesthesia who can provide informed consent and do not have prior gastric surgery or neuromuscular disease.
✕Probably not a fit
Patients undergoing emergency surgery, pregnant patients, or those currently using opioids or anticholinergic medications may not benefit from the study or be eligible to participate.

What this trial studies
This prospective observational study will use bedside gastric ultrasonography to measure antral cross-sectional area and estimate gastric volume in adults scheduled for elective surgery after standard fasting. Participants aged 18–70 with ASA physical status I–III will have a preoperative gastric ultrasound performed by trained anesthesiologists and their recent HbA1c values recorded from preoperative labs. Gastric ultrasound measurements and estimated gastric volumes will be compared across different HbA1c levels. Demographic, anthropometric, fasting duration, and clinical data will be collected for secondary analyses exploring factors associated with delayed gastric emptying.
Why it matters
Potential benefit: If successful, the findings could help clinicians better identify patients at higher risk of pulmonary aspiration and tailor anesthetic management based on HbA1c.
How similar studies have gone: Prior studies have linked diabetes and poor long-term glycemic control to delayed gastric emptying, but applying preoperative gastric ultrasound specifically in relation to HbA1c among surgical patients is relatively novel.
