What is the systematic approach to managing hemoptysis?

Systematic Approach to Management of Hemoptysis

Immediate Assessment and Severity Classification

The first priority is to classify hemoptysis severity and immediately secure the airway in massive hemoptysis, as the rate of bleeding correlates more closely with mortality than total volume. 1

• Massive hemoptysis is defined as ≥200 mL in 24 hours or any bleeding placing the patient at high risk for asphyxiation or exsanguination, with mortality rates of 59-100% in lung cancer patients 2
• Death occurs more commonly from asphyxiation than exsanguination 3
• Two or more opacified lung quadrants on chest radiograph correlate with increased mortality risk 1
• Mild-to-moderate hemoptysis is 10-60 mL in 24 hours 3
• Scant hemoptysis is <10 mL in 24 hours 3

Initial Stabilization for Massive Hemoptysis

For massive hemoptysis, intubate immediately with a single-lumen cuffed endotracheal tube to allow bronchoscopic suctioning and clot removal. 1

• Establish large-bore IV access (ideally 8-Fr central line) for volume resuscitation 1
• Administer high-flow oxygen 1
• Position patient lateral decubitus with bleeding side down 4
• Consider selective right or left mainstem intubation to protect the non-bleeding lung 1
• Never use BiPAP in massive hemoptysis, as positive pressure worsens bleeding 1
• Stop all airway clearance therapies immediately to allow clot formation 1
• Stop aerosolized hypertonic saline 1
• Actively warm the patient and all transfused fluids 1

Critical Laboratory and Medical Management

• Obtain baseline labs: complete blood count, PT/aPTT, Clauss fibrinogen (not derived), type and cross-match 1
• Stop NSAIDs immediately, as they impair platelet function and worsen bleeding 3
• Stop all anticoagulants during active hemoptysis 3
• Administer antibiotics for at least mild hemoptysis (>5 mL), as bleeding may represent pulmonary exacerbation or superimposed bacterial infection 3

Diagnostic Approach Based on Clinical Stability

For Clinically Unstable Patients with Massive Hemoptysis:

Proceed directly to bronchial artery embolization (BAE) without bronchoscopy, as delaying BAE significantly increases mortality. 1

• BAE achieves immediate hemostasis in 73-99% of cases 1
• Over 90% of massive hemoptysis originates from bronchial arteries 1
• Never perform bronchoscopy before BAE in unstable patients 1
• Never delay airway protection in favor of diagnostic procedures when respiratory distress is present 1

For Clinically Stable Patients:

CT chest with IV contrast is the preferred initial diagnostic test, with 80-90% diagnostic accuracy, superior to bronchoscopy (77% vs 8% diagnostic yield). 3

• Chest radiograph is reasonable for confirming benign causes like acute bronchitis or pneumonia, though sensitivity is only 50-70% and suggests etiology in only 26% of cases 1, 2
• CT angiography (CTA) is the standard of care for arterial planning if BAE is being considered 1
• Bronchoscopy provides valuable information on anatomic site and side of bleeding, with 70-80% diagnostic yield 2, 3
• For mild-to-moderate or scant hemoptysis, perform bronchoscopy to identify the source of bleeding 1

Bronchoscopic Management Techniques

For visible central airway lesions, bronchoscopic interventions achieve 80-90% success rates. 1

• Tamponade with iced saline instillation 1
• Bronchial blockade balloons 1
• Topical hemostatic tamponade with oxidized regenerated cellulose mesh arrests hemoptysis in 98% of cases 1
• Thermal ablation: argon plasma coagulation, Nd:YAG laser, or electrocautery 1

Interventional Radiology: Bronchial Artery Embolization

BAE is the first-line therapy for massive hemoptysis with immediate success rates of 73-99%. 1

• Perform BAE without delay in clinically unstable patients 1
• For nonmassive hemoptysis, BAE is increasingly utilized when conservative medical therapy fails or for palliation, with immediate bleeding cessation in 93% of patients 1
• Recurrence of bleeding occurs in 10-55% of cases after BAE, requiring close follow-up 1
• Recurrence within 3 months is often due to incomplete or missed embolization; after 3 months, it's due to vascular collateralization or recanalization 1
• Recent studies show no increased risk of morbidity or mortality for repeat BAE interventions 1

Conditions with Higher Recurrence Rates:

• Chronic pulmonary aspergillomas: 55% recurrence rate 1
• Malignancy 1
• Sarcoidosis 1
• Tuberculosis 3

Radiation Therapy for Malignancy

For unresectable lung cancer with non-massive hemoptysis, external beam radiation therapy (EBRT) provides hemoptysis relief in 81-86% of cases. 1

• EBRT is recommended for distal or parenchymal lesions not amenable to bronchoscopic intervention 1
• Combined high-dose rate brachytherapy with EBRT provides better symptom relief than EBRT alone, though fatal hemoptysis rates range from 7-22% 1
• BAE for malignancy is typically palliative or a temporizing measure prior to definitive surgery 1

Surgical Management

Surgery is reserved as a final therapeutic option when BAE alone is unsuccessful, or for surgically resectable tumors in stable patients with 50-70% survival rates. 1

• For aspergillomas causing hemoptysis, definitive surgical treatment following initial BAE is recommended due to 55% recurrence rates 1
• Surgical mortality for massive hemoptysis is 16%, associated with blood aspiration into contralateral lung and pneumonectomy 1
• Surgery is generally not recommended for massive hemoptysis due to advanced disease and extremely high mortality rates of 90-100% 2

Post-Intervention Management

Admit all patients with massive hemoptysis to intensive care for monitoring of coagulation parameters, hemoglobin, blood gases, and ongoing bleeding. 1

• Start venous thromboprophylaxis as soon as bleeding is controlled 1
• Avoid hyperventilation and excessive positive end-expiratory pressure in hypovolemic patients 1
• Do not rely on single hematocrit measurements as an isolated marker for bleeding severity 1

Management of Recurrent Hemoptysis

For recurrent hemoptysis following initial treatment, repeat BAE is the primary therapeutic option. 1

• Perform CT angiography or CT with IV contrast before repeat BAE for arterial mapping 1
• Recent studies consistently show no increased risk of morbidity or mortality for repeat interventions 1

Admission Criteria

• Scant hemoptysis may not require admission and can be managed outpatient 3
• Massive hemoptysis should always be admitted to the hospital 3
• Mild-to-moderate hemoptysis (10-60 mL) requires individualized assessment, with some patients manageable at home if they have had previous bouts of bleeding 3

Common Etiologies by Geographic Region

• Resource-rich countries: Bronchiectasis (most common in many series), lung cancer, chronic obstructive pulmonary disease, respiratory infections 1, 5
• Resource-limited areas: Active tuberculosis remains the leading cause 1, 5
