A 64-year-old man is currently receiving treatment in the intensive care unit for a severe exacerbation of cystic fibrosis-related bronchiectasis. Twenty minutes ago, he experienced an episode of massive hemoptysis, expectorating approximately 500 mL of bright red blood. He was immediately intubated with an 8.0-mm single-lumen endotracheal tube to secure the airway. A bedside flexible bronchoscopy performed through the endotracheal tube reveals continuous, high-volume arterial bleeding originating from the right lower lobe bronchus. Despite targeted application of cold saline and epinephrine, the bleeding remains uncontrolled and is now rapidly flooding the trachea and spilling into the left mainstem bronchus. The patient's oxygen saturation has declined from 96% to 82% despite mechanical ventilation with a fraction of inspired oxygen of 1.0. Blood pressure is 112/74 mmHg and heart rate is 118/min. Which of the following is the most appropriate immediate next step in management?
- ARemove the current endotracheal tube and insert a double-lumen endotracheal tube
- BTransport the patient to the interventional radiology suite for bronchial artery embolization
- CObtain a stat computed tomography angiography of the chest to map the bronchial vasculature
- Advance the endotracheal tube into the left mainstem bronchusAnswer
- EAdminister intravenous propranolol to reduce bleeding source pressure
