Subjects
USG was used to measure the internal transversal subglottic diameter on the crichoid cartilago level while the head was in sniffing position. After USG measurement was recorded, Cole formula was used to measure internal diameter of uncuffed endotracheal tube.
USG
USG used was SonoSite® M-Turbo Bothell, WA, USA, probe linear (Array HFL 38 frekuensi 6-13 MHz). Internal subglottic diameter equals external diameter of the uncuffed endotracheal tube or trachea diameter, result rounded to the smallest uncuffed endotracheal tube size.
Cole Formula
Internal diameter of the uncuffed endotracheal tube equals (age in years/4) + 4mm.
