A 58-year-old man with a history of treated pulmonary tuberculosis presents to the emergency department after expectorating approximately 600 mL of bright red blood over the past two hours. He is in severe respiratory distress, tachypneic, and diaphoretic. His oxygen saturation is 84% on room air. A portable chest radiograph reveals a large cavitary lesion in the right upper lobe with surrounding new alveolar opacities, consistent with the source of bleeding. Arrange the following management steps for this patient's massive hemoptysis in the most appropriate sequential order, from the initial life-saving intervention to the definitive therapy of last resort.
- 1Secure the airway with endotracheal intubation and place the patient in the right lateral decubitus position
- 2Perform bronchoscopy to localize the bleeding site, suction the airway, and attempt local hemostasis
- 3Perform bronchial artery embolization via interventional radiology
- 4Perform thoracotomy and surgical lung resection
Cevap
The correct sequence for managing massive hemoptysis is: airway protection and dependent positioning of the bleeding lung, followed by bronchoscopy, then bronchial artery embolization, and finally surgical resection as a last resort.
In massive hemoptysis (defined as expectorating >600 mL of blood in 24 hours or a rate causing respiratory compromise), the immediate threat to life is asphyxiation. Therefore, securing the airway with endotracheal intubation and positioning the patient with the bleeding lung down (right lateral decubitus in this case) is the most critical first step. Once the airway is stabilized, bronchoscopy is indicated to localize the bleeding, clear the airways, and potentially temporize the bleeding. If bleeding continues, bronchial artery embolization is the standard definitive therapy. Surgical resection is associated with high mortality and is reserved strictly for cases where embolization fails or is impossible.

Anahtar Kavram
Management of massive hemoptysis prioritizes airway protection (intubation and dependent positioning of the bleeding lung), followed by bronchoscopy for localization, bronchial artery embolization as primary definitive therapy, and surgery only as a last resort.
