Massive Haemoptysis
This is an anaesthetic crisis
Priority is to: * Decontaminate the airway * Maintain oxygenation
Large haemorrhage into the pulmonary tree which:
- Is variably defined as 100-1000mL of haemoptysis/day
- May precipitate cardiac arrest secondary to hypoxia
##Emergency Management
Immediately:
- Protect airway
- Large, single-lumen ETT
- Suction catheter/bronchoscopic decontamination
- Consider lung isolation
- Bronchial blocker
- May be passed outside the ETT and placed under bronchoscopic guidance
- Consider use of a 14Fr Fogarty catheter
- Endobronchial tube
- Bronchial blocker
- Large, single-lumen ETT
- Haemodynamic resuscitation
- Cardiac arrest is common
- Hypoxia is almost always the cause
- Hypovolaemia is rarely significant
Definitive treatment:
- Source control
Options include:- Rigid bronchoscopy
- Interventional angiography
Bronchial angiography and embolisation.
- Note risk of paralysis due to loss of spinal perfusion
- Thoracotomy
- Correction of coagulopathy
Epidemiology and Risk Factors
Pathophysiology
- 90% of haemorrhage comes from the bronchial circulation
These bleeds are dependent on systemic blood pressure.
Aetiology
Causes can be divided into:
- Airway
- Trauma
- Suction
- Foreign body
- Tracheo-arterial fistula
- Blunt/penetrating
- Primary lung disease
- Infective
- Mycobacterial
- Fungal
- Lung abscess
- Parasitic
- Hydatid cyst
- Paragonimiasis
- Necrotising pneumonia
Staphylococcus, Klebsiella, Legionella.
- Neoplasm
- Primary
- Metastases
- Sarcoma
- Infective
- Cardiac
- LV failure
- Mitral stenosis
- Vascular
- Vasculitis
- Wegener’s granulomatosis
- Behcet’s disease
- Vascular
- AVM
- PE
- Vasculitis
- Coagulopathy
- von Willebrand’s Disease
- Haemophilias
- Anticoagulants
- Thrombocytopenia
- Iatrogenic
- PAC
- Bronchoscopy
- Biopsy
- Transtracheal aspiration

Investigations
Management
Medical:
- If related to PAC:
Withdraw catheter slightly and reinflate to provide proximal compression, prior to surgical resection.
Interventional:
- Bronchial artery embolisation
- Used for life-threatening haemoptysis
- Failure in up to 10%
- Surgical resection
Treatment of choice when site is localised and patient can tolerate resection.
