This narrative review summarizes the current knowledge on point-of-care ultrasound (POCUS) of gastric contents in order to inform an assessment of aspiration risk and guide anesthetic management at the bedside. An I-AIM framework (Indication, Acquisition, Interpretation, and Medical decision-making) is used to summarize and organize the content areas. This narrative review spans the breadth of the literature on pediatric and adult subjects as well as on special patient populations such as obstetric and severely obese individuals. Areas that need further investigation include the diagnostic accuracy of gastric POCUS from a Bayesian perspective and the impact of POCUS on patient outcomes, healthcare economics, and educational curricula.

Observational Study
Subclavian and axillary vessel anatomy: a prospective observational ultrasound study.
The primary objective of this study was to define the ultrasound-derived anatomy of the axillary/subclavian vessels. As a secondary objective, we evaluated the relationship between the vascular anatomy and demographic, anthropometric, and hemodynamic data of patients. ⋯ In patients undergoing cardiac surgery, axillary vessel anatomy varied considerably, and the patients' hemodynamics could not predict the size of the axillary vessels. Only the patients' weight correlated moderately with the depth of the vein.
