Gastric ultrasound in patients receiving semaglutide: a prospective, multicentre, matched control study

This study compared gastric ultrasound findings in patients receiving semaglutide treatment with matched controls, thereby accounting directly for baseline delayed gastric emptying. Our findings highlight a persistently elevated pulmonary aspiration risk, even after withholding one administration of semaglutide and accounting for age, diabetes mellitus status and obesity. Where available, gastric ultrasound should be used to guide individualised anaesthetic management and optimise peri-operative safety.
