Ultrasound reveals whether a common anesthesia maneuver actually protects Kids' lungs
NCT ID NCT04190524
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses ultrasound to check if pressing on the neck (cricoid pressure) during anesthesia prevents stomach contents from entering the lungs in children. Researchers will measure the esophagus before and after pressure in 35 kids aged 0-17. They also test if pressing from the side works better than the standard downward pressure.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
cricoid pressure (manual pressure on the neck)
What this could lead to
If successful, this could improve how doctors prevent stomach contents from entering the lungs during anesthesia in children.
