Noncuffed endotracheal tubes are recommended for children under the age of?

• A. 10 years
• B. 12 years
• C. 8 years
• D. 5 years

Answer: (C)

Pediatric airway anatomy drives this choice. In young children the subglottic region just below the vocal cords—around the cricoid ring—is the narrowest part of the airway and remains relatively small as they grow. Inflating a cuffed tube in that area can press on the mucosa, causing edema and risking subglottic stenosis. Because of this, an uncuffed tube is preferred in smaller children to avoid cuff-related injury while still providing an effective seal. As children reach about eight years old, the airway diameter has typically expanded enough to tolerate a cuffed tube with careful sizing and controlled cuff pressures. So uncuffed tubes are recommended for children under eight years.
