TRACHEOBRONCHIAL INJURIES IN CHILDREN

Five patients with tracheobronchial injuries secondary to blunt thoracic trauma were reviewed over a 9-year period. Bronchial disruption occurred in four cases and tracheal disruption in one. Of the four patients with bronchial disruption, a major airway injury was suspected early because of a large air leak or persistent pulmonary atelectasis. However, definitive diagnosis by bronchoscopy was delayed from 4 to 16 days due to initial response to conservative management. Bronchial repair was achieved in every case; additional lobectomy was required in only one instance. Postoperative bronchial stenosis occurred in one patient and responded well to dilatation. The child with a blowout perforation of the trachea was diagnosed early by bronchoscopy and was successfully managed without surgery. Tracheobronchial injury is one of the most severe injuries caused by blunt trauma and requires a high index of suspicion for early diagnosis and surgery. Bronchial repair is successful in most instances. © 1991.
