Bronchial injury

Background

• Primarily due to rapid deceleration
• Most occur within 2cm of carina

Clinical Features

• Dyspnea, hemoptysis, subcutaneous emphysema, sternal tenderness
• Pneumothorax, pneumomediastinum

Management

• All lacerations of the bronchi involving more than 1/3 of the circumference need surg
