Summary
Two patients experienced sudden stridor unresponsive to typical treatments. They were diagnosed with paradoxical vocal cord motion (PVCM), a condition requiring specific emergency department (ED) management strategies.
Area of Science:
- Emergency Medicine
- Otolaryngology
- Respiratory Medicine
Background:
- Acute stridor can present a diagnostic challenge in emergency settings.
- Standard medical therapies may not always resolve stridor effectively.
Observation:
- Two cases of acute-onset stridor unresponsive to conventional medical management are presented.
- Diagnostic evaluation revealed paradoxical vocal cord motion (PVCM) as the underlying cause.
Findings:
- Paradoxical vocal cord motion (PVCM) can mimic other causes of upper airway obstruction.
- Prompt recognition and appropriate diagnostic workup are crucial for identifying PVCM.
Implications:
- This case review highlights the importance of considering PVCM in refractory stridor.
- Effective emergency department (ED) management protocols for PVCM are essential for patient outcomes.
