Ultrasound reveals: does throat pressure really prevent aspiration in children?
NCT ID NCT04190524
First seen Apr 24, 2026 · Last updated May 14, 2026 · Updated 4 times
Summary
This study uses ultrasound to see if pressing on the throat (cricoid pressure) during anesthesia actually blocks the esophagus and prevents stomach contents from entering the lungs in children. Researchers will check the esophagus position and size before and after pressure, and test if pressing from the side works better. About 35 children will be observed to improve safety during intubation.
