uncuffed endotracheal tube
Endotracheal tube without an inflatable cuff, traditionally used in children under 8 years due to anatomical airway differences.
Full Definition
An endotracheal tube design without an inflatable balloon seal, historically preferred for pediatric patients under 8 years of age because the cricoid ring serves as a natural seal in children's airways. The narrowest part of a child's airway is at the cricoid cartilage rather than the vocal cords, making cuffed tubes potentially unnecessary and risking mucosal injury. However, recent evidence supports cuffed tube use in certain pediatric cases for improved ventilation and reduced environmental pollution from anesthetic gases.
Usage
Usage note: Traditional pediatric choice, though cuffed tubes increasingly used with low pressures
