Commonest cause of death in penetrating injury of chest -: (A) Tracheobronchial injury, (B) Oesophageal rupture, (C) Pulmonary laceration, (D) Chylothorax
Answer is A. Ans is 'a' ie Tracheobronchial injury Tracheobronchial injuries are so fatal that most pts. die at the scene or during transpo as a result of poor ventilation. The other options are so easy to rule out as they are rarely the cause of death. I could not find the MC cause of death after penetrating injury but among the 4 options provided Tracheobronchial is definitely the right answer. No doubts about it.
