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
• Critical illness
• Inability to provide informed consent
• <18 years of age

The study population will include non-critically ill adults 18 years and older undergoing various elective surgical procedures at the University of North Carolina Medical Center

Deidentified individual data that supports the results will be shared beginning 9 to 36 months following publication provided the investigator who proposes to use the data has approval from an Institutional Review Board (IRB), Independent Ethics Committee (IEC), or Research Ethics Board (REB), as applicable, and executes a data use/sharing agreement with UNC.
