Carefully review the following clinical vignettes of patients presenting after major thoracic or thoracoabdominal trauma. Match each patient presentation with the most appropriate next step in their diagnosis or management.
- A 45-year-old driver in a high-speed collision is hemodynamically stable. Portable chest plain film shows a widened mediastinum and depression of the left mainstem bronchus.Computed tomography angiography of the chest
- A 33-year-old restrained passenger in a head-on collision has abdominal tenderness and left shoulder pain. Portable chest plain film shows abdominal viscera in the left thoracic cavity.Emergent exploratory laparotomy
- A 52-year-old cyclist struck by a car has adjacent rib fractures in two places. He has paradoxical chest wall motion but normal oxygenation and is breathing spontaneously without distress.Epidural analgesia and close respiratory monitoring
- A 27-year-old victim of a penetrating thoracic wound has a chest tube placed that immediately drains 1,600 mL of bright red blood. He remains hypotensive despite fluid resuscitation.Emergent exploratory thoracotomy
Answer
The presentations map to their specific standard-of-care interventions: suspected blunt aortic injury requires CT angiography, acute diaphragmatic rupture requires exploratory laparotomy, flail chest without respiratory failure requires pain control, and massive hemothorax requires emergent thoracotomy.
Each matching pair correctly identifies the gold standard next step based on trauma protocols. Stable patients with high-risk mechanisms for aortic injury need CTA. Acute diaphragmatic injuries must be approached abdominally. Flail chest primarily requires pain control to maintain pulmonary mechanics. Massive hemothorax requires direct surgical hemostasis via the chest.
