Investigators evaluated the accuracy of the tracheal rapid ultrasound saline test (TRUST) to confirm proper endotracheal tube (ETT) depth in children ages 3 months to 18 years undergoing intubation at an ambulatory surgery center. The TRUST technique identifies correct ETT depth by the visualization of a saline-filled cuff at the level of the suprasternal notch.
For each of 42 children (mean age, 6 years), an ETT was placed in the incorrect endobronchial position as well as at the correct tracheal depth (approximately 3 cm above the carina); placement was confirmed by fiberoptic bronchoscopy. With a 5- to 10-Hz linear transducer placed in a transverse orientation at the level of the suprasternal notch, ultrasound video recordings were taken …
