Using Point-of-Care-Ultrasound (POCUS) to Assess Gastric Contents Among Fasting Pre-operative Patients Taking GLP-1 Agonists.

Given the increased prescription of GLP-1 agonists for both diabetes and obesity management and the implications of the proposed delayed gastric emptying in the setting of an anesthetic, it is critical to determine if patients taking GLP-1 agonists have an increased rate of delayed gastric emptying. The purpose of this prospective gastric ultrasound evaluation of pre-operative patients is to determine the incidence of a full stomach despite a standard pre-operative fasting period.

Inclusion Criteria:

• GLP-1 agonist use within previous 30 days
• Appropriately fasted per standard guidelines

Exclusion Criteria:

• History of gastric surgery / gastric volume reduction
