A 45-year-old man with a history of treated pulmonary tuberculosis is brought to the emergency department after coughing up approximately 800 mL of bright red blood over the past 8 hours. On arrival, he is in severe respiratory distress and coughing continuously. His blood pressure is 90/60 mm Hg, heart rate is 122/min, and oxygen saturation is 84% on room air. A bedside chest radiograph reveals a large cavitary lesion in the right upper lobe. Arrange the following interventions in the most appropriate sequential order for managing this patient's condition, starting with the most immediate priority and ending with the treatment of last resort.
- 1Secure the airway via endotracheal intubation
- 2Perform bronchoscopy to localize the bleeding
- 3Perform bronchial artery embolization
- 4Perform surgical pulmonary resection
Answer
The correct sequence is to first secure the airway via endotracheal intubation, followed by bronchoscopy to localize the bleeding, then bronchial artery embolization, and finally surgical pulmonary resection as a last resort.
Massive hemoptysis (defined as >600 mL of blood in 24 hours or bleeding that causes respiratory/hemodynamic compromise) requires a strict, prioritized approach. The most immediate threat to life is asphyxiation resulting from blood filling the dependent airways, not hemorrhagic shock. Therefore, the very first step must be establishing a patent airway via endotracheal intubation, along with positioning the patient with the bleeding lung in the dependent position (e.g., right lateral decubitus in this patient). Once the patient is stabilized and ventilated, bronchoscopy is the next appropriate step to localize the bleeding and attempt topical therapy. When bronchoscopy fails to arrest the hemorrhage definitively, bronchial artery embolization is the standard of care. Surgical pulmonary resection carries very high mortality in the acute emergency setting and is considered a last resort when embolization is unsuccessful.

Key Concept
Stepwise management of massive hemoptysis: airway protection -> bronchoscopic evaluation -> endovascular embolization -> surgical resection.
