Intubation-induced tracheal stenosis -- the urgent need for permanent solution

Area of Science:

• Medicine
• Critical Care Medicine
• Anesthesiology

Background:

• Tracheal damage is common at the site of endotracheal tube cuffs.
• Despite shifts to low-pressure cuffs, significant tracheal lesions persist.

Observation:

• A case of tracheal stenosis occurred after 7 days of intubation with a standard cuffed tube.
• Cuff pressure was subjectively assessed, leading to stenosis at the cuff site.
• Computed axial tomography confirmed tracheal stenosis, necessitating emergency tracheostomy.

Findings:

• Standard endotracheal tube cuffs, even when assessed subjectively, can cause tracheal stenosis.
• The Lanz endotracheal tube features a pilot balloon for automatic intra-cuff pressure regulation.

Implications:

• Clinicians should be aware of the risk of tracheal stenosis from standard endotracheal tubes.
• The Lanz endotracheal tube is recommended for intensive care and situations with potential cuff pressure increases.
• Implementing pressure-regulating tubes may prevent tracheal stenosis and improve patient outcomes.
