Preoperative Gastric Volume and High-Risk Gastric Content in Patients With Type 2 Diabetes Mellitus

Brief summary (registry, in English)

This prospective observational study will evaluate adult patients with type 2 diabetes mellitus who are scheduled for elective surgery. Immediately before preoperative gastric ultrasonography, capillary fasting blood glucose will be measured. Gastric contents will be assessed qualitatively in the supine and right lateral decubitus positions, and residual gastric volume will be estimated using the antral cross-sectional area measured in the right lateral decubitus position. The primary objective is to evaluate the association between fasting capillary blood glucose and the presence of a high-risk stomach. A high-risk stomach will be defined as the presence of solid gastric contents, Perlas Grade 2 gastric contents, or an estimated gastric volume greater than 1.5 mL/kg. Secondary objectives include determining the prevalence of a high-risk stomach and evaluating its associations with demographic characteristics, diabetes-related factors, comorbidities, fasting duration, medication use, gastroparesis-related symptoms, and routine laboratory parameters.
