Abstract:Objective?To observe the value of flexible bronchoscopy (fiberoptic bronchoscopy/electronic bron choscopy, abbreviation bronchoscopy) in the diagnosis and treatment of patients with decannulation difficult after tracheotomy.?Methods?17 cases with decannulation difficult after tracheotomy which were diagnosed and treated by flexible bronchoscopy were reviewed and evaluated.?Result?Among the 17 patients with decannulation difficult, except one failure in decannulation because of upper airway scar contracture with atresia after brain injury, the rest was successful, and decannulation rate was 94.1%. Except one patient with displacement of metal stents, and one patient with breathing difficulty after the decannulation, there was no other adverse reactions and deadly complications.?Conclusion?Flexible bronchoscope plays an important part in the diagnosis and treatment of the patients with decannulation difficult after tracheotomy. It is safe and reliable, so it is worthy of clinical promotion.
