Tracheal lacerations are iatrogenic, localized, low impact injuries with longitudinal tears (in about 1:20,000 intubations). In contrast traumatic tracheobronchial ruptures are high velocity injuries with horizontal transections. Between 1986 and 2002, we treated 27 tracheobronchial injuries (8 bronchial 3 of them iatrogenic, 19 tracheal 17 of them iatrogenic (+1 horizontal rupture+1 tracheoesophageal stabbing)). Extension of the tears 5-12 cm. All bronchial ruptures, the tracheal rupture as well as six iatrogenic tracheal tears have been managed operatively. All the other underwent conservative treatment.(1) critically ill patients, (2) delay in diagnosis >72 h, and (3) refusal of operation. It consists in endotracheal intubation for 5-9 days. This way we prevent pressure peaks as well as retention achieving a continuous control. Conservative group: 12/13 patients survived, neither stenosis nor megatrachea. Operative group: 1 patient died (MOF), 1 postoperative stenosis (Montgomery tube for 2 months). Tracheobronchial ruptures have to be operated. Lacerations show frequently discrete clinical signs, but typical X-rays. They can be dealt with conservatively in the majority of cases as well as operatively. According to our experience, conservative treatment is safe and shows a mortality as low or lower than operative procedures.
