A LONG-AXIS (LAX) view of the trachea and larynx in a 3-yr-old girl after intubation with a cuffed endotracheal tube (4.0-mm internal diameter) (fig. A), and a short-axis (SAX) view of the trachea with a transverse tracheal width of 7.0 mm before intubation (fig. B), were obtained using an ultrasound apparatus with an L12-2 MHz probe. The cricothyroid membrane was palpated around 25 mm from the suprasternal notch etch. Hyperechoic shadows mostly indicated anterior membranes of the cricoid or tracheal cartilage. The saline-inflated cuff position was confirmed below the cricoid cartilage in the trachea. The suprasternal notch is usually above the carina, and cuff position also may lie above the carina.
