Delayed gastric emptying produced by GLP-1 receptor agonists has raised concern that residual gastric contents may persist beyond conventional preoperative fasting periods, with a corresponding risk of pulmonary aspiration during anaesthesia.[1]

The evidence is largely case reports and imaging series showing residual gastric contents on ultrasound after standard fasting in people taking these agents, rather than trials demonstrating an increased aspiration rate. Aspiration is rare enough that a randomised demonstration is impractical.[1]
