Massive hemoptysis
Stem
A 45-year-old man, 76 kg, with old tuberculosis and a right upper lobe cavity has coughed up about 400 mL of bright red blood over three hours. In the emergency department his SpO2 is 88% on a non-rebreather mask, heart rate 118, blood pressure 104/62, and he is still coughing blood. CT angiography shows the bleeding comes from the right upper lobe. Interventional radiology is on the way, and you are asked to secure his airway.
Question
How will you secure his airway and protect his lungs?
Ideal answer
HeadlineThe immediate threat is asphyxiation: he needs an airway now, with blood kept out of the left lung while I keep him oxygenated.1 I lie him right side down.
- Call for help early. Interventional pulmonology, radiology and thoracic surgery, because bronchoscopy, embolization or surgery follows.
- Two large-bore IVs; count, crossmatch, coagulation.1 He is tachycardic and still bleeding.
- Rapid sequence induction, two suctions ready, because the airway is full of blood; preoxygenated sitting forward or right side down; a hemodynamically gentle agent and rocuronium.
- Large single-lumen tube, 8.5 to 9 mm, so a bronchoscope can suction and treat through it.1
- Still soiling: isolate the left lung. The tube over a bronchoscope into the left main bronchus, or a bronchial blocker in the right main bronchus.1
Watch for: Saturation, airway pressure and blood in the tube; then bronchial artery embolization.
Breaking down the answer
- Judge it by effect — the definition varies from 100 to 1,000 mL in 24 hours, so I judge by hypoxemia, shock, the need for intubation or transfusion.1
- Bleeding side down — gravity keeps blood in the lung that is already bleeding.1 Changes if: the side is unknown, when bronchoscopy or CT angiography locates it first.
- Isolation trade-offs — selective left mainstem intubation protects the left lung but leaves the right untreatable, and on the right side it can block the upper lobe;1 a double-lumen tube is hard to place through blood and its narrow lumens limit suction.1
- Know where the blood comes from — about 90% from the bronchial arteries, 5% from the pulmonary arteries and 5% from other systemic vessels,1 which is why embolization targets the bronchial arteries.
- Embolization is the definitive step — immediate success is 70–99%, but rebleeding occurs in 10–57%;1 pooled technical success is about 97%.2 Surgery remains the treatment of choice for trauma, iatrogenic pulmonary artery rupture and resistant aspergilloma.1
- Bronchoscopic temporizing — rigid bronchoscopy, where available, gives the best suction and control.3 Iced saline at 4 °C in 50 mL aliquots stopped bleeding in a small series; topical epinephrine can cause arrhythmias.1
Follow-up question
In the angiography suite, with a blocker in the right main bronchus, he coughs as he is moved onto the table. His SpO2 falls to 72%, airway pressure rises, and blood appears in the tube. What do you do?
Follow-up answer
HeadlineThe blocker has likely dislodged and blood has spilled into the left lung; I tell the radiologist to stop and call for help.
I go to 100% oxygen, suction through the tube and look with the bronchoscope. If I cannot reseat the blocker quickly, I deflate it, advance the tube into the left main bronchus over the scope, and suction the left lung clear. I deepen anesthesia and give more relaxant so he cannot cough the device out again, and start transfusion if he is shocked. Once the saturation recovers, I recheck isolation with the scope before embolization resumes, and the bronchoscope stays on the cart for the rest of the case.
Pitfalls that cost points
- Insisting on a double-lumen tube in a bloody airway.
- Stopping after securing the airway without a plan for embolization or surgery.
Rapid-fire
Q: What fraction of cardiac output goes to the bronchial circulation? A: About 1–2%.1
Q: How lethal is untreated massive hemoptysis? A: Mortality can reach 80% if it is not managed appropriately.1
Q: What is the risk of embolization? A: Major complications are rare, about 0.1%, including spinal cord ischemia and stroke.1
Q: When is nebulized tranexamic acid used? A: For mild to moderate hemoptysis without an imminent airway threat.1
Q: What is the iatrogenic cause anesthesiologists produce? A: Pulmonary artery rupture from a PA catheter, for which surgery remains the treatment of choice.1
