Gastric Ultrasound Assessment for Preoperative Prandial State of Patients Taking Glucagon-Like Peptide-1 Receptor Agonists

Gastric Ultrasound Assessment for Preoperative Prandial State of Patients Taking Glucagon-Like Peptide-1(GLP-1) Receptor Agonists

The purpose of this study is to determine the type of gastric content and quantify the volume of liquid gastric contents using ultrasonography in patients on GLP-1 agonists that have presented for elective surgery and to determine if risk factors are associated with a higher gastric volume in patients on GLP-1 receptor agonists.

Inclusion Criteria:

• Patients taking GLP-1receptor agonists (N=62)
• Patients not taking GLP-1 receptor agonists (N=62)

Exclusion Criteria:

• Previous gastric resection or bypass
• Gastric band in situ
• Previous fundoplication
• Large hiatal hernia
• Pregnant patients
• Recent trauma
• Inability to turn to the right lateral decubitus position
