[Application of percutaneous dilatation tracheotomy in patients with difficult airway].

Objective:To explore the application of percutaneous dilatation tracheotomy for patients with difficult airway. Method:Retrospectively analyzed the clinical data of percutaneous dilatation tracheotomy in difficult airway patients, summarized the difficulties, technical points and advantages. Result:Collecting the clinical data of 28 patients with difficult airway, 20 cases were head and neck tumor recurrence after surgery, radiation and chemotherapy, 3 cases were cervical hematoma, 2 cases were laryngeal neoplasm with heart failure, 2 cases were mandatory spondylitis, and 1 case was airway stenosis. The difficult points for tracheotomy were unable to lie down, neck stiffness, displacement of the trachea, coagulation disorder, unclear neck structure, etc. All patients accepted percutaneous dilatation tracheotomy, including cone and forceps dilatation tracheotomy, with none complication. Conclusion:Percutaneous dilatation tracheotomy was a safe, rapid and minimally invasive surgical method for patients with difficult airway requiring tracheotomy, and could be used as the preferred solution.
