Ultrasound peers into Children's stomachs after Pre-Surgery drink
NCT ID NCT04130022
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Children scheduled for surgery often drink a calming premedication liquid before anesthesia. Doctors want to know whether that drink leaves much fluid in the stomach, which could raise the risk of aspiration during surgery. Researchers use bedside ultrasound to measure stomach volume in children before and after they drink the premedication. The study aims to see if the stomach looks the same after the drink as it did before.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bedside point-of-care ultrasound
- What this could lead to
- If the premedication drink leaves little fluid in the stomach, doctors may feel more confident letting children drink it before surgery.
- What could go wrong
- This is a small observational study in children without stomach problems. The results may not apply to children who are obese, have reflux, or take other medications.
