Korean consensus-based recommendations for preanesthetic gastric ultrasound and anesthetic considerations for GLP-1 receptor agonist-based therapy: a consensus statement from Clinical Practice Guideline Committee of the Korean Society of Anesthesiologists.

Although contemporary fasting guidelines recommend minimum fasting intervals to reduce aspiration risk, adherence does not guarantee an empty stomach, particularly in patients with delayed gastric emptying or those receiving medications that impair gastrointestinal motility, such as glucagon-like peptide-1 receptor agonist (GLP-1 RA)-based therapies.

Preanesthetic gastric ultrasound has emerged as a practical point-of-care modality for the qualitative and quantitative assessment of gastric content and volume, enabling individualized aspiration risk stratification in selected patients.
