In all participants, the transverse diameter of the subglottis was measured with ultrasound during apnea. An endotracheal tube was chosen with the outer diameter matched to the measured subglottic airway diameter. An age\u2010based (Motoyama\u2010Khine) and height\u2010based (Broselow) endotracheal tube size was calculated.

Best\u2010fit tube internal diameter was the resultant tube internal diameter that met the previously stated conditions.
