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.
