Letter to the Editor: Neonatal airway ultrasound, useful reference, limited guidance for anesthesiologists

Abstract

We read with great interest the prospective study by Paprocki and colleagues establishing ultrasound (US) reference values for laryngeal and tracheal structures in 300 healthy neonates examined in the first days of life. The authors should be commended for generating sex stratified percentile data under standardized conditions and for demonstrating bedside feasibility—contributions that advance image-based assessment in neonatology and pediatrics.
