Tracheobronchial rupture caused by blunt chest trauma: acute respiratory management.

The clinical management of 12 patients with major intrathoracic tracheobronchial rupture (complete, 3; incomplete, 9) due to blunt trauma has been reviewed and compared with that of two groups of patients with chest injuries not involving the tracheobronchial tree, 17 patients with multiple rib fractures and 17 with chest injuries requiring thoracotomy for control of pneumothorax and hemothorax. The effect of injury on ventilatory function was significantly greater in the patients with tracheobronchial injury in whom an elevated PCO2 at the time of admission was associated with a poor prognosis. Conventional ventilatory management with endotracheal intubation and positive pressure ventilation causing increased air leakage produced further deterioration of pulmonary function in four of the patients with tracheobronchial disruption. The use of a double-lumen endobronchial tube in two patients with tracheobronchial rupture facilitated ventilatory support and subsequent operative management.
