Effects of GLP-1 Agonists on Gastric Volume

A gastric ultrasound will be completed on every patient and administered the same way in each arm. The patient will be placed in supine position. A curvilinear ultrasound probe will be placed on the sagittal plane below the xiphoid process. The probe will then slide along the costal margin to the right until the gastric antrum is identified. At this point, the ultrasound image will be obtained, and appropriate measurements will be taken. The patient will be placed in the right lateral decubitus position and the above procedure will be repeated.
