We aimed to assess the accuracy of ultrasonographic measurement of the antral cross-sectional area (CSA) in the preprocedural evaluation of gastric contents and volume in fasted patients > 60 yr of age scheduled for gastroscopy under sedation. ⋯ Patients > 60 yr of age scheduled for gastroscopy under sedation had a higher incidence of a full stomach detected with ultrasound compared with a younger cohort, which is potentially associated with a higher aspiration risk. We calculated a cut-off value of RLD CSA for detecting gastric volume in patients > 60 yr of age of approximately 10 cm2, which may help to quickly assess patients at risk of aspiration.

Case Reports
Semaglutide, delayed gastric emptying, and intraoperative pulmonary aspiration: a case report.
We report a case in which the use of semaglutide for weight loss was associated with delayed gastric emptying and intraoperative pulmonary aspiration of gastric contents. ⋯ Patients using semaglutide and other glucagon-like peptide 1 agonists for weight management may require specific precautions during induction of anesthesia to prevent pulmonary aspiration of gastric contents.

Glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1RAs) have become increasingly popular as both diabetic and weight loss therapies. One effect of this class of medication is delayed gastric emptying, which may impact the risk of aspiration during anesthesia delivery. ⋯ This study provides preliminary evidence that GLP-1RAs may affect gastric emptying and residual gastric contents following an overnight fast and two hours after clear liquids, which may have implications for aspiration risk during anesthetic care.
