Key result
A prospective randomized controlled study was conducted to compare ultrasound with age-based formulas for endotracheal tube size estimation in paediatric patients, but no results are reported.
Why the study?
Conventional age-based formulas do not reflect actual tracheal diameter for endotracheal tube selection, often necessitating repeated laryngoscopy in paediatric patients.
Does endotracheal tube size estimation using ultrasonography improve appropriate tube selection and reduce tube exchanges in paediatric patients compared to age-based formulas?

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

R et al. (2023) conducted an RCT in Paediatric patients requiring endotracheal intubation. Ultrasound for endotracheal tube size estimation vs. Age-based formula was evaluated on Appropriate endotracheal tube size determination. A prospective randomized controlled study was conducted to compare ultrasound with age-based formulas for endotracheal tube size estimation in paediatric patients, but no results are reported.
