A 58-year-old man with a history of adequately treated cavitary pulmonary tuberculosis presents to the emergency department coughing up copious amounts of bright red blood. He reports expectorating approximately 600 mL of blood over the past 4 hours. On presentation, his blood pressure is 90/60 mm Hg, heart rate is 118/min, respiratory rate is 28/min, and oxygen saturation is 86% on room air. He appears in severe respiratory distress and is coughing continuously, struggling to clear his airway. Coagulation studies are within normal limits. Chest radiograph demonstrates a residual cavity in the right upper lobe with new surrounding airspace opacities. Arrange the following procedural and surgical interventions in the most appropriate sequential order for managing this patient's life-threatening condition.
- 1Perform endotracheal intubation to secure the airway and isolate the bleeding lung.
- 2Perform flexible or rigid bronchoscopy to visually localize the source of hemorrhage.
- 3Perform bronchial artery embolization (BAE) via percutaneous catheterization.
- 4Perform a thoracotomy with pulmonary lobectomy or pneumonectomy.
