A Silicone-Based Wire-Reinforced Tracheal Tube with a Hemispherical Bevel Reduces Nasal Morbidity for Nasotracheal Intubation

Abstract

The pharyngeal and tracheal placement phases of nasotracheal intubation require fewer attempts with a silicone-based wire-reinforced tracheal tube with a hemispherical bevel than with a polyvinyl chloride-based precurved tracheal tube with a conventional diagonal bevel, but the glottic placement phase requires more attempts. Nasal morbidity is less common with the silicone tracheal tube.
