Background[1]
- Also known as "vocal cord dysfunction"
- Occurs from abnormal adduction of the vocal cords during inspiration
- Lack of familiarity may lead to delayed diagnosis and unnecessary intubation or surgical airway procedures
Clinical Features
Differential Diagnosis
Evaluation
Workup
Diagnosis
Management
- Reassurance and breathing techniques to resolve stridor:
- Jaw thrust while breathing
- Pursed lip breathing through straw or endotracheal tube
- Inhale through nose for 3 seconds and exhale through pursed lips for 3 seconds
- "Pant like a dog" - rhythmic breathing with mouth open and tongue protruding forward
- 3 sniffs - take 2 quick then 1 slow inhalational sniffs through the nose, exhale slowly through mouth
- Mild sedatives (eg benzodiazepines) may be effective in cases refractory to breathing techniques[2]
