[Tracheobronchial injury].

We studied 6 cases of tracheobronchial injury due to the blunt chest truma in our department. All patients were male of 19 to 60 years of age. Injured sites were main bronchus in 2, tracheobronchial portion in 2, cervical trachea and main bronchus in 1, cervical trachea in 1. In a case of cervical tracheal injury and 2 cases of tracheobronchial injury, emergent operation was performed on the day of accident. Other cases with the main bronchial injury underwent conservative treatment at first, but subsequent bronchoplasty was necessary for them due to the bronchial stenosis. After the surgery for 2 cases of tracheobronchial injury, mechanical ventilation with double lumen tube was continued to reduce the airway pressure for the anastomotic sites. In conclusion, early surgical treatment is recommended for the airway injury and the respiratory management using double lumen tube after surgery may be helpful in preventing trouble at the anastomosis.
