[Airway obstruction after tracheostomy in a neurologically impaired child]

Area of Science:

• Pediatric Anesthesiology
• Pediatric Critical Care
• Pediatric Otolaryngology

Background:

• Neurologically impaired children often require prolonged tracheal intubation.
• Tracheostomy is a common intervention for managing airway issues in these patients.
• Anesthesia emergence can present unique challenges in patients with pre-existing airway compromise.

Observation:

• A 14-year-old boy with neurological impairment experienced sudden inability to ventilate lungs during emergence from general anesthesia for tracheostomy.
• Airway obstruction persisted despite attempts with the anesthetic circuit and tracheostomy tube, leading to decreased oxygen saturation and bradycardia.
• Ventilation became possible only when respiratory effort decreased, suggesting a dynamic airway issue.

Findings:

• Flexible bronchoscopy revealed tracheomalacia, characterized by slight collapse of the trachea.
• The patient's symptoms resolved with decreased respiratory effort, consistent with dynamic airway collapse.
• Tracheomalacia was identified as the likely cause of the sudden, severe ventilation difficulty.

Implications:

• Tracheomalacia should be considered in neurologically impaired children experiencing sudden ventilation problems during or after anesthesia.
• Early diagnosis and management of tracheomalacia are crucial for preventing life-threatening hypoxemia and cardiovascular compromise.
• This case highlights the importance of thorough airway assessment in pediatric patients with neurological impairment undergoing airway procedures.
