Endotracheal tube size estimation using ultrasonography in paediatric patients: A prospective randomized controlled study

Endotracheal intubation (ETT) is the gold standard for airway management and one of most commonly performed procedure. Improper selection endotracheal tube it results in complications like, inadequate ventilation, poor reliability end-tidal gas monitoring, leakage anaesthetic gases into operating room environment enhanced risk aspiration. The conventional age-based formulas doesn’t reflect actual tracheal diameter tube. Hence repeated laryngoscopy often required to place an appropriate sized especially paediatric patients. Recent studies have documented that anatomical structures supraglottic, glottic subglottic regions can be evaluated by ultrasound. Therefore, present study was conducted determine size patients using ultrasound comparing with age based formula.
