Tracheal rupture in a child with blunt chest injury

Summary A 10-year-old boy fell from a tree and sustained blunt injury to his chest. He was brought to the hospital (6 h later) with difficulty in breathing and inability to speak. There was a bruise on the neck and extensive subcutaneous emphysema over the neck and chest and decreased air entry over the right hemithorax. Radiographs revealed a right-sided pneumothorax, pneumomediastinum and tracheal deviation. An intercostal drain (with underwater seal) was inserted and he was transferred to the operating room for bronchoscopy. Anesthesia was induced with IV midazolam and ketamine. The trachea was intubated orally and anesthesia maintained with spontaneous breathing of halothane in oxygen. Flexible fiberoptic bronchoscopy performed via the tracheal tube revealed no injury to bronchi or carina. Bronchoscopy through the tracheal tube withdrawn to the level of the vocal cords revealed a 1-cm long posterior longitudinal tear approximately 2–3 cm below the cords. The surgeons planned a definitive tracheostomy distal to the traumatic tracheal opening. This was difficult and initially unsuccessful because of subcutaneous emphysema. A ureteric catheter was introduced through the tracheal tube and a tracheostomy tube mounted on the fiberoptic bronchoscope, which was then inserted through the surgical tracheostome. This followed the ureteric catheter into the distal trachea and the trachea was successfully cannulated. We review the mechanism of tracheal injuries with special reference to its occurrence in children with blunt injury. We discuss the airway management in these potentially life-threatening injuries.
