Popis: Abstract Background and aims Endotracheal intubation is a crucial skill in anesthesia. Uncuffed pediatric endotracheal tube (ETT) size can be calculated by various methods like age-based formula or by using ultrasound to measure minimal transverse subglottic diameter (MTSD). This study aimed to compare both age-based formula and ultrasound to assess the advantage of routine use of ultrasound to determine pediatric ETT size. Materials and methods Forty children of 2–10 years of age, ASA class ≤ II, Mallampati airway classes I and II, scheduled for surgery away from the head and neck, were included. Uncuffed ETT size for each child was calculated using age-based formula. After induction of balanced general anesthesia, an ultrasound was done to measure MTSD and an endotracheal tube was selected accordingly. After intubation, an air leak test was done and the ETT was accordingly changed (if needed). Results ETT size by age-based formula strongly correlated with the size measured by ultrasound (Pearson correlation 0.913; P
