Massive Hemoptysis - ICU Management

Quick Answer

Massive hemoptysis is a life-threatening emergency defined as expectoration of >200-600 mL of blood within 24 hours or bleeding at a rate causing haemodynamic or respiratory compromise. The primary cause of death is asphyxiation from airway obstruction, NOT exsanguination. [1,2]

Key Clinical Features:

• Coughing bright red blood (vs. haematemesis which is darker, coffee-ground)
• Respiratory distress, hypoxia, inability to clear airway
• Haemodynamic instability in severe cases
• May have known underlying pulmonary pathology (TB, bronchiectasis, malignancy)

Emergency Management (First 15 minutes):

1. Position bleeding side DOWN - protect the non-bleeding lung
2. Large-bore ETT (≥8.0 mm) - enables bronchoscopy and suctioning
3. Selective mainstem intubation if single-lumen tube only available
4. Call interventional radiology - bronchial artery embolization is first-line definitive therapy

ICU Mortality: 6.5-38% overall; up to 50-80% if mechanically ventilated [3,4]

Must-Know Facts:

• 90-95% of hemoptysis originates from bronchial arteries (systemic pressure), NOT pulmonary arteries [5]
• Bronchial artery embolization (BAE) has 70-90% immediate success rate [6]
• Surgery reserved for BAE failure, localized disease, or specific pathologies
• Bronchiectasis, TB, and malignancy are leading causes in Australia/NZ [7]

Key Points

Must-Know Facts

1. Definition Variability: Massive hemoptysis is variably defined as >100 mL/hour, >200 mL/24h, or >600 mL/24h. Life-threatening hemoptysis is better defined as bleeding causing respiratory or haemodynamic compromise, regardless of volume. [1,2]

2. Asphyxiation is the Killer: Death occurs from airway obstruction and alveolar flooding, NOT from haemorrhagic shock. The anatomical dead space is only ~150 mL; filling this with blood causes rapid hypoxaemia. [8]

3. Bronchial Artery Source (90-95%): Most hemoptysis originates from hypertrophied bronchial arteries under systemic pressure (120/80 mmHg), explaining why bleeding is often torrential. [5,9]

4. Pulmonary Artery Source (5%): Rasmussen aneurysms (TB cavities), pulmonary AVMs (HHT), and iatrogenic PA catheter injuries cause pulmonary artery bleeding - these may require different embolization approaches. [10,11]

5. BAE is First-Line Definitive Therapy: Bronchial artery embolization achieves immediate haemostasis in 70-90% of cases and is preferred over surgery due to lower mortality. [6,12]

6. Rebleeding is Common: Up to 10-30% of patients experience recurrent hemoptysis after BAE, often due to non-bronchial systemic collaterals or underlying disease progression. [13]

7. Bronchoscopy for Localization, NOT Definitive Therapy: Flexible bronchoscopy localizes bleeding in 73-93% of cases but provides only temporary haemostatic measures. [14]

8. Surgery Reserved for Failures: Emergency surgery carries mortality of 15-40%; elective surgery after stabilization has <10% mortality. Lobectomy preferred over pneumonectomy. [15]

9. Aetiology Determines Prognosis: Malignancy-related hemoptysis has worst prognosis. Bronchiectasis and TB generally have better outcomes with BAE. [3]

10. CF-Specific Considerations: Recurrent hemoptysis in CF may affect lung transplant candidacy. BAE is first-line; transplant evaluation if FEV1 <30% or frequent severe episodes. [16]

Memory Aids

BLOOD Mnemonic for Initial Management:

• Bleeding side DOWN - protect non-bleeding lung
• Large ETT (≥8.0 mm) - enables bronchoscopy
• Oxygen and optimize haemodynamics
• Obtain CT angiography if stable / bronchoscopy if unstable
• Definitive therapy - BAE or surgery

Causes of Massive Hemoptysis - "BACTIM":

• Bronchiectasis / Bronchogenic carcinoma
• Aspergilloma / AVM (pulmonary)
• Cystic fibrosis / Coagulopathy
• Tuberculosis (active or post-TB sequelae)
• Iatrogenic (PA catheter, biopsy)
• Mitral stenosis / Mycetoma

Definition & Epidemiology

Definition

Massive Hemoptysis lacks a universally accepted definition, with various thresholds used:

Clinical Definition (Preferred): Hemoptysis that poses an immediate threat to life due to airway compromise, hypoxaemia, or haemodynamic instability, regardless of measured volume. [1,2,8]

Severity Classification:

Epidemiology

International Data:

• Hemoptysis accounts for 1-4% of pulmonary outpatient visits
• Massive hemoptysis represents 5-15% of all hemoptysis cases
• ICU admission rate for massive hemoptysis: 50-70%
• Need for mechanical ventilation: 20-40% of massive hemoptysis [17]

Australian/NZ Data:

• Bronchiectasis is the leading cause in Indigenous communities (post-TB sequelae)
• TB rates in Indigenous Australians 8-10× higher than non-Indigenous population [18,19]
• CF affects ~3,500 Australians; hemoptysis occurs in 4-18% annually [20]
• Aspergilloma complicating prior TB/bronchiectasis significant in Northern Australia

Aetiology by Region:

Mortality:

• Overall ICU mortality: 6.5-38% [3,4]
• Mechanically ventilated patients: 50-80%
• Conservative management only: ~70% (historical)
• With BAE: 10-25%
• Malignancy-related: highest mortality [3]

Risk Factors for Poor Outcome (Fartoukh Score components) [3]:

• Need for mechanical ventilation
• Malignancy as underlying cause
• Aspergillus infection
• Pulmonary artery involvement on imaging
• Radiographic extent >2 lung quadrants

High-Risk Populations

Aboriginal and Torres Strait Islander Peoples:

• Higher rates of TB (8-10× increased risk) [18,19]
• Higher rates of bronchiectasis (post-infectious, childhood pneumonia)
• Remote community location delays definitive care
• Cultural considerations in consent and family involvement

Māori Population:

• Higher rates of bronchiectasis and TB
• Health inequities in access to specialist services
• Whānau (family) involvement in decision-making essential

Cystic Fibrosis Population:

• Hemoptysis affects 4-18% annually
• Progressive bronchiectasis and bronchial artery hypertrophy
• May affect lung transplant candidacy
• CFTR modulators (Trikafta) reducing hemoptysis incidence [21]

Applied Basic Sciences

Anatomy

Bronchial Artery Anatomy (Source in 90-95% of Hemoptysis)

Origin and Course:

• Arise from descending thoracic aorta at T5-T6 level
• Variable anatomy (Cauldwell classification) [9]:
  • "Type I (40%): 1 right (from intercostobronchial trunk) + 2 left bronchial arteries"
  • "Type II (21%): 1 right + 1 left"
  • "Type III (21%): 2 right + 2 left"
  • "Type IV (10%): 1 right + 1 left + aberrant from aortic arch"
• Right bronchial artery often shares origin with right intercostal artery (intercostobronchial trunk)

Clinical Significance:

• Bronchial arteries are under systemic pressure (120/80 mmHg)
• Chronic inflammation → bronchial artery hypertrophy and neovascularization
• Enlarged, tortuous vessels are fragile and prone to rupture
• Non-bronchial systemic collaterals (intercostal, subclavian, internal mammary, phrenic) can develop in chronic disease

Anterior Spinal Artery Risk:

• Artery of Adamkiewicz may arise from intercostobronchial trunk
• Risk of spinal cord infarction with inadvertent embolization
• Incidence of neurological complications: <1% but devastating [22]

Pulmonary Artery Anatomy (Source in 5% of Hemoptysis)

Low-Pressure System:

• Pulmonary arteries: ~25/10 mmHg (vs systemic 120/80)
• Carry 95% of total lung blood flow but only 5% of hemoptysis
• Thin-walled vessels less prone to rupture

Conditions Causing Pulmonary Artery Bleeding:

• Rasmussen aneurysm: PA erosion into TB cavity [10,23]
• Pulmonary AVM: Direct PA-PV communication (HHT association) [11,24]
• Necrotizing pneumonia: PA erosion
• PA catheter-induced rupture: Iatrogenic [25]
• Pulmonary artery aneurysm: Behçet's disease, infection

Radiological Anatomy for BAE:

• Pre-procedure CTA identifies bronchial artery origins
• Anomalous origins must be identified (aortic arch, subclavian)
• Non-bronchial systemic supply mapped for comprehensive embolization

Physiology

Dual Blood Supply of the Lung

Pathophysiological Basis of Bronchial Artery Bleeding [5,9]:

1. Chronic inflammation (bronchiectasis, TB, CF) triggers:

   • Bronchial artery hypertrophy (↑ diameter)
   • Neovascularization (new vessel formation)
   • Bronchial-pulmonary arterial anastomoses

2. Fragile, dilated vessels:

   • Thin-walled compared to normal bronchial arteries
   • Under systemic pressure
   • Rupture into bronchial lumen

3. Systemic collateral recruitment:

   • Intercostal arteries
   • Subclavian branches
   • Internal mammary artery
   • Inferior phrenic arteries
   • These may require separate embolization

Physiology of Asphyxiation

Why Volume Matters Less Than Rate:

• Anatomical dead space: ~150 mL
• Functional residual capacity: ~2,400 mL
• Rapid filling of airways with blood → V/Q mismatch → hypoxaemia
• Blood in alveoli → impaired surfactant function → atelectasis
• Clot formation → airway obstruction

Protective Mechanisms That Fail:

• Cough reflex overwhelmed by blood volume
• Mucociliary clearance ineffective for large clots
• Laryngeal closure insufficient for massive bleeding

Pharmacology

Haemostatic Agents

Tranexamic Acid (TXA):

• Mechanism: Lysine analogue, inhibits plasminogen activation → prevents fibrin breakdown
• Dosing: IV 1g bolus then 1g over 8 hours; Nebulized 500mg TDS (off-label)
• Evidence: Limited RCT data; case series suggest benefit [26]
• Side effects: Nausea, diarrhoea; theoretical thrombosis risk
• TGA/PBS: Available; no specific hemoptysis indication

Vitamin K (Phytomenadione):

• Indication: Warfarin reversal, vitamin K deficiency
• Dosing: IV 5-10 mg slow infusion
• Onset: 6-8 hours for effect

Prothrombin Complex Concentrate (Prothrombinex):

• Indication: Urgent warfarin reversal
• Dosing: 25-50 IU/kg based on INR
• Onset: Within 30 minutes

Fresh Frozen Plasma:

• Indication: Multiple factor deficiency, DIC
• Dosing: 10-15 mL/kg
• Limitations: Volume, transfusion reactions, slow administration

Vasoactive Agents for Bronchoscopy

Topical Adrenaline (Epinephrine) [27,28]:

• Mechanism: α-adrenergic vasoconstriction
• Concentration: 1:10,000 to 1:100,000 dilution
• Dosing: 1-2 mL aliquots via bronchoscope
• Caution: Systemic absorption → tachycardia, hypertension, arrhythmias
• Maximum dose: Generally <10 mL of 1:10,000

Cold Saline Lavage [29]:

• Mechanism: Hypothermic vasoconstriction
• Temperature: 4°C iced saline
• Dosing: 50-100 mL aliquots (total up to 500-1000 mL)
• Evidence: Conlan et al. demonstrated efficacy in massive hemoptysis

Topical Vasopressin:

• Mechanism: V1 receptor-mediated vasoconstriction
• Use: Less common; case reports only
• Caution: Coronary vasoconstriction risk

Pathology

Aetiology-Specific Pathology

Bronchiectasis [30,31]:

• Permanent bronchial dilatation with chronic infection
• Bronchial artery hypertrophy: vessels can reach 2-3 mm diameter (normal <1 mm)
• Neovascularization within bronchial walls
• Erosion into hypertrophied vessels during exacerbations

Tuberculosis [10,23]:

• Active TB: Granulomatous inflammation, caseous necrosis
• Rasmussen aneurysm: PA branch eroded by TB cavity (5% of hemoptysis cases)
• Post-TB sequelae: Bronchiectasis, aspergilloma, fibrous scarring
• Broncholithiasis: Calcified lymph nodes eroding into bronchi

Aspergilloma (Mycetoma) [32,33]:

• Fungal ball within pre-existing lung cavity (often post-TB)
• Aspergillus releases proteolytic enzymes → cavity wall erosion
• Chronic inflammation → bronchial artery hypertrophy
• Recurrence common after BAE (15-30%)

Bronchogenic Carcinoma [34,35]:

• Central tumours erode into bronchial vessels
• Squamous cell carcinoma most common to cause hemoptysis
• Tumour necrosis exposes vessels
• May involve pulmonary artery (poor prognosis)
• BAE less effective; may require palliative radiation

Pulmonary Arteriovenous Malformation [11,24]:

• Direct PA-PV communication (no capillary bed)
• Associated with HHT (Osler-Weber-Rendu) in 80-90%
• Thin-walled vessels prone to rupture
• Risk increases during pregnancy (increased cardiac output)
• Treated by pulmonary artery embolization (NOT bronchial)

Cystic Fibrosis [16,20]:

• Progressive bronchiectasis from chronic Pseudomonas infection
• Extensive bronchial artery hypertrophy
• Multiple non-bronchial systemic collaterals
• Higher BAE rebleeding rates (up to 30-40%)

• Associated symptoms: Chest pain, fever, dyspnoea, weight loss
• Previous episodes: Prior hemoptysis, frequency, interventions
• Past medical history: TB, bronchiectasis, CF, malignancy, cardiac disease

Differentiating Hemoptysis from Haematemesis:

Examination:

A - Airway:

• Patent vs obstructed
• Blood in oropharynx
• Stridor (rare unless massive clot)
• Ability to cough and clear secretions

B - Breathing:

• Respiratory rate (typically elevated >20/min)
• SpO2 (hypoxia common)
• Work of breathing (accessory muscle use)
• Auscultation: Gurgling (blood in airways), focal crackles/wheeze (localizing sign)
• Percussion: Dullness suggests consolidation/haemothorax

C - Circulation:

• Heart rate (tachycardia)
• Blood pressure (hypotension late sign)
• Peripheral perfusion (cool, clammy if shocked)
• Signs of chronic disease (clubbing, cachexia)

D - Disability:

• Conscious state (decreasing GCS suggests severe hypoxia)
• Agitation, confusion (hypoxaemia, impending arrest)

E - Exposure:

• Signs of underlying disease:
  • Clubbing (bronchiectasis, lung cancer, CF)
  • Telangiectasia (HHT → pulmonary AVM)
  • Lymphadenopathy (malignancy, TB)
  • Cachexia (malignancy, chronic infection)

Severity Assessment

Clinical Indicators of Life-Threatening Hemoptysis:

• Active bleeding with inability to maintain clear airway
• SpO2 <90% despite supplemental oxygen
• Haemodynamic instability (SBP <90 or requiring vasopressors)
• Decreasing conscious state
• Aspiration to contralateral lung (bilateral infiltrates)

Fartoukh Prognostic Score [3]:

Score ≥3: High risk of ICU mortality (>50%)

Investigations

Laboratory Investigations

Bedside Tests:

Arterial Blood Gas:

• Primary purpose: Assess oxygenation, ventilation, acid-base status
• Typical findings in severe hemoptysis:
  • Hypoxaemia (PaO2 <60 mmHg)
  • Initially respiratory alkalosis (hyperventilation)
  • Later metabolic acidosis (shock)
  • Lactate elevation if haemodynamic compromise

Blood Tests:

Specific Tests Based on Clinical Suspicion:

Imaging

Chest X-Ray:

• First-line, immediately available
• Findings: Unilateral infiltrate, mass, cavity, bronchiectasis
• Localization accuracy: Only 45-65%
• Limitations: May be normal in early/small bleeds; blood may obscure source
• Serial CXRs useful for progression

CT Chest with Angiography (CTA) [36]:

• Gold standard for stable patients
• Identifies:
  • Source of bleeding (sensitivity 70-88%)
  • Underlying pathology (bronchiectasis, mass, cavity, AVM)
  • Bronchial artery anatomy for BAE planning
  • Non-bronchial systemic collaterals
• Protocol: Arterial phase timing for bronchial arteries
• Sensitivity for bleeding source: 70-88%

CT Angiography vs Bronchoscopy for Localization:

Bronchial Angiography:

• Performed in interventional radiology suite
• Diagnostic AND therapeutic (BAE in same session)
• Identifies bronchial artery origins, collaterals
• Selective catheterization for embolization

Bronchoscopy [14,27,37]

Timing and Indications:

• Urgent bronchoscopy (within 24-48h) recommended for massive hemoptysis
• Can be performed at bedside in intubated patients
• Flexible bronchoscopy: Most common, through ETT ≥8.0 mm
• Rigid bronchoscopy: Better suction, airway control; requires OR/GA

Diagnostic Role:

• Localization of bleeding to lobe/segment: 73-93% success
• Direct visualization of lesions (tumour, bronchitis)
• BAL for cytology, microbiology
• Biopsy if mass lesion visible (caution: may worsen bleeding)

Flexible vs Rigid Bronchoscopy:

Timing of Bronchoscopy vs CT:

• If haemodynamically unstable: Intubate first, bedside bronchoscopy
• If stable but active bleeding: CT angiography first (identifies source and plans BAE)
• Post-BAE: Bronchoscopy to clear clots, assess airway
• Ideally both: CT for planning, bronchoscopy for confirmation

ICU Management

Initial Resuscitation (First 15 Minutes)

A - Airway (CRITICAL PRIORITY):

Positioning:

• Bleeding side DOWN (lateral decubitus position)
• Prevents blood gravitating to non-bleeding lung
• Maintains gas exchange in unaffected lung
• If side unknown: sit upright or trendelenburg (controversial)

Indications for Intubation:

• Respiratory failure (SpO2 <90% despite high-flow oxygen)
• Unable to protect airway (decreasing GCS, weak cough)
• Massive ongoing bleeding
• Need for bronchoscopy/BAE under GA

Endotracheal Tube Selection:

• Large single-lumen ETT (≥8.0 mm): First choice in emergencies
  • Allows passage of bronchoscope
  • Enables adequate suctioning
  • Bronchial blocker can be placed through it

Selective Mainstem Intubation (if single-lumen only available) [38]:

• Advance standard ETT into mainstem bronchus of NON-bleeding lung
• Right mainstem: Rotate tube 90° right; risk of RUL occlusion
• Left mainstem: More difficult (angle); advance deeply and confirm with bronchoscope
• Protects healthy lung from blood aspiration

Double-Lumen Tube (DLT) [39]:

• Provides definitive lung isolation
• Difficult to place in emergency (requires fibreoptic confirmation)
• Smaller lumens (limits suctioning of thick clots)
• Reserve for OR setting with experienced operator

Bronchial Blockers [40]:

• Arndt, Cohen, or Fuji bronchial blockers
• Placed through multiport adaptor alongside ETT
• Balloon inflated in bleeding bronchus/lobe
• Advantage: Can use through existing ETT
• Disadvantage: May dislodge, does not allow suctioning beyond balloon

Airway Device Comparison:

B - Breathing:

• High-flow oxygen (aim SpO2 >94%)
• If intubated: Lung-protective ventilation to non-isolated lung
• If lung isolation in place: Ventilate non-bleeding lung only
• Avoid high PEEP to bleeding lung (may worsen haemorrhage)

C - Circulation:

• Large-bore IV access × 2 (14G or 16G)
• Crossmatch blood (4-6 units PRBCs immediately available)
• Fluid resuscitation: Crystalloid initially, then blood products
• Target MAP >65 mmHg (but avoid hypertension which may worsen bleeding)
• Avoid aggressive fluid resuscitation (dilutional coagulopathy)

D - Disability:

• GCS monitoring
• Sedation for intubated patients (propofol/fentanyl)
• Avoid coughing (may worsen bleeding)

E - Everything Else:

• Correct coagulopathy: Vitamin K, FFP, platelets, PCC as needed
• Stop anticoagulants: Warfarin, DOACs, heparin
• Stop antiplatelet agents: Aspirin, clopidogrel (risk-benefit)
• Tranexamic acid: 1g IV bolus (off-label but commonly used)
• Alert teams: Interventional radiology, cardiothoracic surgery, respiratory medicine

Bronchoscopic Management [14,27,28,29]

Goals of Bronchoscopy:

1. Localize the bleeding source (lobe/segment)
2. Temporizing haemostatic measures
3. Clear clots to improve ventilation
4. Facilitate bronchial blocker placement

Bronchoscopic Haemostatic Techniques:

Cold Saline Lavage [29]:

• Iced saline (4°C) via bronchoscope channel
• Aliquots of 30-50 mL, repeat as needed (total up to 500-1000 mL)
• Mechanism: Local vasoconstriction
• Evidence: Conlan et al. demonstrated efficacy in massive hemoptysis (PMID: 3717540)

Topical Adrenaline (Epinephrine) [27,28]:

• Dilution: 1:10,000 to 1:100,000
• Dose: 1-2 mL aliquots (maximum ~10 mL of 1:10,000)
• Mechanism: α-adrenergic vasoconstriction
• Caution: Monitor for systemic effects (tachycardia, hypertension)

Balloon Tamponade [41]:

• Fogarty catheter (4-7 French) or dedicated bronchial blocker
• Advance to bleeding segment, inflate balloon
• Provides mechanical tamponade
• Maintains airway patency in non-bleeding lung
• Leave in place as bridge to BAE (up to 24-48 hours)

Oxidized Cellulose (Surgicel) [42]:

• Hemostatic mesh applied via bronchoscope
• Forms scaffold for clot formation
• Useful for accessible, localized bleeding
• Evidence: Valipour et al. (PMID: 15939744)

Other Agents:

• Thrombin/fibrin glue: Case reports only
• Tranexamic acid topical: Nebulized or direct application
• Argon plasma coagulation: For visible vessel/tumour
• Laser: For tumour-related bleeding (Nd:YAG)

Rigid Bronchoscopy Indications:

• Massive exsanguinating hemorrhage
• Need for clot extraction
• Large airway tumour causing bleeding
• Failed flexible bronchoscopy

Bronchial Artery Embolization (BAE) [6,12,13,22,43]

Indications:

• Massive or life-threatening hemoptysis
• Recurrent significant hemoptysis
• Failed conservative/bronchoscopic management
• Pre-operative stabilization before elective surgery

Contraindications:

• Allergy to contrast (relative; can premedicate)
• Renal impairment (relative; risk-benefit)
• Inability to cannulate bronchial arteries (anatomic variant)
• Anterior spinal artery arising from bronchial artery (relative; superselective technique)

Technique:

1. Femoral artery access
2. Descending thoracic aortography to map bronchial arteries
3. Selective catheterization of bronchial arteries
4. Identification of abnormal vessels (hypertrophy, hypervascularity, shunting)
5. Confirm no spinal artery supply
6. Embolization with:
   • Polyvinyl alcohol (PVA) particles (300-500 μm)
   • Microspheres (Embospheres)
   • Gelfoam (temporary)
   • Coils (larger vessels)
7. Non-bronchial systemic collaterals embolized if identified

Embolic Agents:

Success Rates:

• Immediate haemostasis: 70-90% [6,12]
• Recurrence at 1 year: 10-30%
• Recurrence at 5 years: 20-50% (higher in CF, aspergilloma)

Complications:

• Chest pain/dysphagia: 10-30% (bronchial artery supplies oesophagus)
• Fever: 5-10%
• Transient cortical blindness: <1%
• Spinal cord ischaemia: <1% (devastating if occurs) [22]
• Bronchial stenosis: Rare
• Stroke: <1%

Predictors of BAE Failure/Recurrence:

• Aspergilloma (highest recurrence, up to 40-50%)
• Cystic fibrosis (extensive collaterals)
• Non-bronchial systemic supply not embolized
• Pulmonary artery source (requires PA embolization)
• Underlying malignancy
• Incomplete initial embolization

Surgical Management [15,44,45]

Indications for Surgery:

• Absolute:

  • BAE failure with ongoing life-threatening bleeding
  • Pulmonary artery source not amenable to embolization
  • Iatrogenic PA catheter rupture
  • Chest trauma with major vessel injury

• Relative/Elective:

  • Localized resectable disease (aspergilloma, bronchiectasis, carcinoid)
  • Recurrent hemoptysis despite repeated BAE
  • Mycetoma with symptoms
  • Hydatid cyst

Surgical Options:

Emergency vs Elective Surgery:

• Emergency surgery mortality: 15-40% (up to 50% for pneumonectomy)
• Elective surgery after stabilization: <10%
• Strategy: Stabilize with BAE → plan elective surgery if indicated

Contraindications to Surgery:

• Bilateral disease
• Insufficient pulmonary reserve (FEV1 <1L for lobectomy)
• Unresectable malignancy
• Severe comorbidities
• Active TB (surgery after initial treatment)

Perioperative Management:

• DLT placement for lung isolation
• Bronchoscopy to clear clots before surgery
• Cross-matched blood available (6+ units)
• Experienced thoracic anaesthesia team

Resuscitation and Blood Products

Transfusion Triggers:

• Massive transfusion protocol if >4 units PRBCs in 1 hour or >10 units in 24 hours
• Target Hb >70-80 g/L (higher if ongoing bleeding)
• Platelet count >50 × 10⁹/L (>100 if CNS/ongoing bleeding)
• Fibrinogen >1.5 g/L
• INR <1.5, APTT <1.5× normal

Massive Transfusion Protocol:

• PRBCs : FFP : Platelets = 1:1:1 ratio
• Cryoprecipitate if fibrinogen <1.5 g/L
• TXA 1g IV (evidence from CRASH-2, extrapolated)
• Calcium replacement (citrate in blood products chelates Ca²⁺)
• Avoid hypothermia (blood warmer)

Correction of Anticoagulation:

• Warfarin: Vitamin K 5-10 mg IV + Prothrombinex 25-50 IU/kg
• DOACs: Idarucizumab for dabigatran; Andexanet for anti-Xa agents (if available)
• Heparin: Protamine (1 mg per 100 units heparin)
• Antiplatelet agents: Platelet transfusion; desmopressin may help

Specific Aetiologies

Tuberculosis [10,18,19,23,46]

Active TB:

• Start anti-TB therapy (RIPE regimen)
• Isolation precautions (airborne)
• BAE is first-line for hemoptysis
• Surgery if localized and treatment complete

Rasmussen Aneurysm:

• Pulmonary artery erosion into TB cavity
• 5% of TB-related hemoptysis
• May require pulmonary artery embolization (NOT bronchial)
• High mortality if ruptures
• Consider surgical resection if stable

Post-TB Sequelae:

• Bronchiectasis → bronchial artery bleeding
• Aspergilloma in residual cavities
• Broncholithiasis

Australian/Indigenous Context [18,19]:

• TB rates 8-10× higher in Indigenous Australians
• Remote communities: delayed diagnosis, advanced disease
• Post-TB bronchiectasis common
• Cultural considerations in prolonged treatment
• RFDS retrieval for remote patients

Bronchiectasis [30,31]

Management:

• BAE is first-line for hemoptysis
• Optimize underlying disease (antibiotics for infection)
• Airway clearance (once bleeding controlled)
• Consider surgical resection if localized, recurrent

Non-CF Bronchiectasis:

• Common in Indigenous Australians (post-infectious)
• Often multi-lobar (limits surgical options)
• Good response to BAE

Cystic Fibrosis [16,20,21]

Classification in CF:

• Mild: <5 mL blood-streaked sputum
• Moderate: 5-240 mL/day
• Severe: >240 mL/day or >100 mL/day for several days

Acute Management:

• Stop airway clearance temporarily
• Stop NSAIDs (impair platelet function)
• Vitamin K supplementation
• Tranexamic acid (IV or nebulized)
• BAE for severe/massive hemoptysis

Lung Transplant Considerations:

• Recurrent massive hemoptysis is relative indication for transplant
• FEV1 <30% or rapidly declining
• Referral to transplant centre (Alfred, St Vincent's, Prince Charles, Fiona Stanley)
• CFTR modulators (Trikafta) reducing hemoptysis incidence [21]

Australian CF Services:

• Cystic Fibrosis Australia provides guidelines
• State-based CF centres
• BAE expertise in major centres

Aspergilloma (Mycetoma) [32,33]

Pathophysiology:

• Aspergillus colonizes pre-existing lung cavity
• Fungal ball (mycetoma) causes chronic inflammation
• Bronchial artery hypertrophy around cavity
• High recurrence rate after BAE (30-50%)

Management:

• BAE as temporizing measure
• Antifungal therapy: Limited efficacy for aspergilloma (Itraconazole, Voriconazole)
• Surgical resection: Definitive but high-risk
• Cavernostomy: Alternative for poor surgical candidates

Pulmonary AVM / HHT [11,24,47]

Hereditary Hemorrhagic Telangiectasia (HHT):

• 80-90% of PAVMs occur in HHT patients
• Curaçao criteria for diagnosis
• Screen first-degree relatives

Hemoptysis in PAVM:

• Pulmonary artery source (NOT bronchial)
• Requires pulmonary artery embolization (coils/plugs)
• Risk increases in pregnancy
• Screening: Contrast echocardiography (bubble study)

Management:

• PAVM embolization: Feeding artery >3 mm diameter
• Follow-up CT for reperfusion
• Lifelong monitoring

Malignancy [34,35]

Bronchogenic Carcinoma:

• Squamous cell carcinoma most common to cause hemoptysis
• Central tumours erode into vessels
• BAE less effective than other causes
• Options:
  • BAE (temporizing)
  • External beam radiotherapy (palliative)
  • Endobronchial laser/APC
  • Stenting (for airway obstruction)
  • Surgical resection (if operable)

Palliative Considerations:

• Goals of care discussion essential
• May not be appropriate to pursue aggressive intervention
• Symptom management focus
• Family communication

Australian/NZ Context

Indigenous Health Considerations

Aboriginal and Torres Strait Islander Peoples [18,19]:

• TB rates: 8-10× higher than non-Indigenous Australians
• Bronchiectasis: High prevalence from childhood respiratory infections
• Remote communities: Delayed presentation, limited access to interventional radiology
• Cultural considerations:
  • Aboriginal Health Worker/Aboriginal Liaison Officer involvement
  • Family/community involvement in decision-making
  • Sorry Business may affect treatment timing
  • Health literacy considerations
  • Interpreter services for language groups

Retrieval Considerations:

• RFDS protocols for remote hemoptysis

• Blood product availability in remote areas limited
• Consider intubation before retrieval if significant bleeding

Māori Health (New Zealand):

• Higher rates of bronchiectasis and TB
• Whānau (extended family) involvement in care decisions
• Tikanga (cultural protocols) considerations
• Māori Health Workers as cultural liaisons
• Te Tiriti o Waitangi obligations for equitable care

Retrieval Medicine

Pre-Hospital/Retrieval Considerations:

• Early intubation if significant bleeding (before retrieval)

• Cross-matched blood if available
• Communication with receiving centre
• Interventional radiology on standby at receiving hospital

Remote Area Challenges:

• Limited blood products
• No interventional radiology capability

Monitoring & Complications

ICU-Specific Monitoring

Continuous Monitoring:

• SpO2 (target >94%)
• ECG (arrhythmias from hypoxia, adrenaline)
• Arterial line for MAP, ABGs
• Hourly urine output
• Haemoglobin (q4-6h if active bleeding)
• Coagulation studies (q6-12h)

Airway Monitoring:

• ETT position (especially if DLT or bronchial blocker)
• Bronchoscopic re-evaluation if recurrent bleeding
• Cuff pressure (prevent aspiration around cuff)

Post-BAE Monitoring:

• Chest pain (common, usually self-limiting)
• Dysphagia (oesophageal ischaemia)
• Neurological status (spinal cord ischaemia)
• Recurrent hemoptysis

Complications

Early Complications (First 24-48 hours):

Aspiration to Contralateral Lung:

• Incidence: 20-30% of massive hemoptysis
• Bilateral infiltrates on CXR
• Worsening hypoxaemia
• Prevention: Bleeding side down, early intubation
• Management: Bronchoscopy to clear blood, lung-protective ventilation

Airway Obstruction from Clot:

• Sudden desaturation, high airway pressures
• Management: Bronchoscopy, suction, clot extraction

Haemorrhagic Shock:

• Less common cause of death than asphyxiation
• Manage with blood products, vasopressors
• Source control essential

Recurrent Bleeding Post-BAE:

• 10-30% at 1 year
• May require repeat BAE (different collaterals)
• Consider surgical resection if recurrent

Late Complications (Beyond 48 hours):

Bronchial Stenosis:

• Rare complication of BAE
• May present with persistent cough, stridor
• Management: Bronchoscopic dilation, stenting

Pulmonary Infarction:

• Rare with modern particle embolization
• More common with non-target embolization

Spinal Cord Ischaemia [22]:

• <1% incidence
• Devastating if occurs (paraplegia)
• Prevention: Careful angiography, avoid anterior spinal artery
• If suspected: MRI spine, high-dose steroids (controversial)

Hospital-Acquired Pneumonia/VAP:

• Aspiration of blood is inflammatory
• Prophylactic antibiotics controversial
• Monitor for infection, treat if clinical evidence

Post-Traumatic Stress:

• Massive hemoptysis is terrifying experience
• Psychological support for patients and families
• Consider PTSD screening in survivors

• Prepare for urgent intubation if unable to maintain oxygenation or airway (1 mark)
• Have suction immediately available

B - Breathing (1 mark):

• High-flow oxygen aiming SpO2 >94%
• Prepare for intubation given hypoxia despite maximum O2

C - Circulation (2 marks):

• Large-bore IV access × 2 (1 mark)
• Send FBC, coagulation, UEC, G&S, crossmatch 4 units PRBCs (0.5 marks)
• Fluid resuscitation (judicious) and prepare blood products (0.5 marks)

D - Disability: GCS monitoring, analgesia/anxiolysis as needed

E - Escalation (1 mark):

• Alert ICU for admission
• Contact interventional radiology urgently for BAE
• Notify cardiothoracic surgery
• Bronchoscopy team on standby

Question 1.2 (5 marks total)

Airway Management Options:

Large Single-Lumen ETT (≥8.0 mm) (2 marks):

• First-line in emergency - fastest, most familiar
• Allows bronchoscopy and adequate suctioning
• Can place bronchial blocker through it if needed
• Does NOT provide lung isolation

Selective Mainstem Intubation (1 mark):

• Advance ETT into right mainstem bronchus (non-bleeding lung)
• Provides protection of right lung from blood aspiration
• Temporizing measure; limits ventilation to one lung

Bronchial Blocker (1 mark):

• Placed through SLT via multiport adaptor
• Balloon inflated in left mainstem bronchus
• Provides isolation without tube exchange
• Risk of dislodgement

Double-Lumen Tube (1 mark):

• Definitive lung isolation
• Difficult to place in emergency (requires fibreoptic confirmation)
• Narrow lumens limit suctioning
• Reserve for OR/controlled setting with experienced operator

Question 1.3 (4 marks total)

Potential Sources of Bleeding:

Bronchial Artery Source (95% likely) (2 marks):

• Post-TB bronchiectasis with hypertrophied bronchial arteries
• Chronic inflammation → neovascularization
• Managed with bronchial artery embolization

Pulmonary Artery Source (5% but must consider) (2 marks):

• Rasmussen aneurysm: PA branch eroded into TB cavity
• More catastrophic bleeding
• Requires pulmonary artery embolization (NOT bronchial)
• CT angiography can help differentiate
• May require surgical resection if PA source confirmed

Clinical Implication: CT angiography should assess for both bronchial and pulmonary artery sources. If Rasmussen aneurysm suspected, PA embolization or surgery may be required.

Viva Scenarios

Viva Scenario 1: Anatomy and Physiology of Hemoptysis

Stem: "A 50-year-old man with bronchiectasis presents with massive hemoptysis. You have stabilized his airway. Let's discuss the underlying anatomy and your approach to definitive management."

Duration: 12 minutes (2 min reading + 10 min discussion)

---

Opening Question:

"Describe the arterial blood supply to the lungs and explain why hemoptysis usually originates from the bronchial arteries."

Expected Answer (3 minutes):

Dual Blood Supply:

• Pulmonary arteries: 95% of lung blood flow; low pressure (25/10 mmHg); gas exchange function
• Bronchial arteries: 5% of lung blood flow; systemic pressure (120/80 mmHg); nutrient supply to airways

Bronchial Artery Anatomy:

• Arise from descending thoracic aorta (T5-T6 level)
• Variable anatomy (Cauldwell classification)
• Often share origin with intercostal arteries (intercostobronchial trunk)

Why Bronchial Arteries Bleed (90-95% of cases):

• Under systemic pressure (120/80 vs 25/10)
• Chronic inflammation → bronchial artery hypertrophy and neovascularization
• Enlarged vessels are fragile, thin-walled
• Rupture into bronchial lumen causes torrential bleeding

Pulmonary Artery Source (5%):

• Rasmussen aneurysm (TB cavities)
• Pulmonary AVM (HHT)
• Requires different embolization approach

---

Follow-up Question 1:

"What is a Rasmussen aneurysm and how does it differ from typical bronchial artery bleeding?"

Expected Answer:

• Pulmonary artery branch erodes into tuberculosis cavity
• Named after Danish physician Fritz Rasmussen (1868)
• Pulmonary artery wall weakens from chronic inflammation/necrosis
• Aneurysmal dilatation within cavity wall
• Rupture causes massive, often fatal hemorrhage
• Key difference: Pulmonary artery source (not bronchial)
• Requires pulmonary artery embolization or surgical resection
• CT angiography can identify aneurysm

---

Follow-up Question 2:

"Describe the role of non-bronchial systemic collaterals in hemoptysis."

Expected Answer:

• Chronic lung disease recruits collateral supply
• Sources: Intercostal, subclavian, internal mammary, inferior phrenic arteries
• Develop transpleural connections
• May not be embolized at initial BAE → cause of recurrence
• Must be identified on CT angiography
• Require separate catheterization and embolization
• Particularly common in CF and aspergilloma

---

Follow-up Question 3:

"What is the risk of spinal cord ischaemia during BAE?"

Expected Answer:

• Anterior spinal artery may arise from bronchial/intercostal arteries
• Artery of Adamkiewicz: major radicular artery (usually T9-L2)
• May share origin with bronchial arteries
• Inadvertent embolization → anterior spinal artery syndrome
• Incidence: <1% but devastating (paraplegia)
• Prevention: Careful angiography; identify spinal artery; avoid embolization if at risk
• Use particles (more distal occlusion) rather than coils in high-risk cases

---

Viva Scenario 2: Clinical Management and Decision-Making

Stem: "A 65-year-old man with a 40-pack-year smoking history and recently diagnosed lung cancer presents with massive hemoptysis (estimated 600 mL over 6 hours). He is on your ICU for stabilization. Let's discuss your management approach."

Duration: 12 minutes

---

Opening Question:

"What are the key differences in managing hemoptysis in a patient with lung cancer compared to benign causes?"

Expected Answer (2-3 minutes):

Malignancy-Specific Considerations:

• BAE less effective (tumour neovascularization, PA erosion possible)
• May be terminal event (prognosis discussion essential)
• Palliative vs curative intent affects management
• Multiple treatment options beyond BAE

Management Options for Malignancy:

• BAE: Temporizing, less durable response
• External beam radiotherapy: Palliative haemostatic effect
• Endobronchial therapy: Laser, APC, brachytherapy
• Surgical resection: If operable disease
• Stenting: For airway obstruction

Prognostic Implications:

• Hemoptysis in lung cancer associated with worse prognosis
• May indicate central tumour, vascular invasion
• Goals of care discussion essential
• Family involvement in decision-making

---

Follow-up Question 1:

"The family wants 'everything done.' How do you approach this conversation?"

Expected Answer:

• Acknowledge family's wishes and distress
• Explore understanding of prognosis
• Clarify what "everything" means to them
• Explain realistic outcomes (high mortality with malignancy)
• Discuss burden vs benefit of interventions
• Offer time to consider, second opinion if requested
• Involve palliative care if appropriate
• Document discussion

---

Follow-up Question 2:

"What are the indications for emergency surgery in massive hemoptysis?"

Expected Answer:

Absolute Indications:

• BAE failure with ongoing life-threatening bleeding
• Pulmonary artery source not amenable to embolization
• Iatrogenic PA catheter rupture
• Chest trauma with major vessel injury

Relative/Elective Indications:

• Localized resectable disease
• Recurrent hemoptysis despite BAE
• Aspergilloma with symptoms

Surgical Mortality:

• Emergency lobectomy: 5-15%
• Emergency pneumonectomy: 20-50%
• Elective surgery: <10%

Key Principle: Stabilize with BAE first → elective surgery if indicated

---

Follow-up Question 3:

"This patient has COPD with FEV1 of 35% predicted. Does this affect your surgical planning?"

Expected Answer:

• Severe COPD limits surgical options
• Pneumonectomy: Contraindicated (insufficient reserve)
• Lobectomy: High risk, may be possible with careful assessment
• Pre-operative assessment: PFTs, DLCO, 6MWT, cardiopulmonary exercise testing
• Consider limited resection (segmentectomy)
• Discuss with thoracic surgery regarding operability
• May need to focus on non-surgical options (BAE, RT, endobronchial)
