Anesthetic management of tracheal laceration from traumatic dislocation of the first rib: a case report and literature of the review.

Background: Tracheobronchial lacerations from trauma can be life-threatening and present significant challenges for safe anesthetic management. Early recognition of tracheal injuries and prompt airway control can be lifesaving.

Case Presentation: A 56-year-old man with no significant medical history presented with difficulty breathing after a blunt trauma to his chest to the emergency room and was diagnosed with dislocation of the first rib and tracheal laceration after a chest tomography (CT) study. Subcutaneous emphysema in neck area quickly worsened indicating continuous air leak. Emergent surgical repair was scheduled. General anesthesia with maintaining spontaneous ventilation was performed and a 5.5 mm endotracheal tube was placed under the guidance of flexible bronchoscopy. Depth of anesthesia was maintained to achieve a Bispectral Index Score of 40-60. Once the offending first rib was removed, a 7.5 mm endotracheal tube was inserted distal to the laceration site with the guidance of flexible bronchoscopy. Once confirmed location of the endotracheal tube, cisatracurium was administered intravenously and the patient was managed on mechanical ventilation with interval positive pressure ventilation. The operation was successful and he was transferred to the ICU intubated. He then received elective surgical repairs for sternum fracture, multiple rib fractures and hemopneumothorax under general anesthesia on day 5 after the first surgery and was extubated on postoperative day 7. The subsequent course was uneventful. Comprehensive rehabilitation was done for 2 weeks and he was discharged home on postoperative day 41.

Conclusions: Early diagnosis and multidisciplinary collaborations are keys to the successful management of this patient. Flexible bronchoscopy is particularly useful in airway management for urgent trachea tracheal laceration repair.
