Introduction
Is it really haemoptysis?
- pseudohemoptysis
- blood coming from the upper airways eg. posterior epistaxis, sinusitis,
- haematemesis
- pH < 7, blood is dark red or brown not bright red
aetiology
- 60% are infective causes - see acute cough in the adult, and remember tuberculosis (TB), aspergilloma, lung abscess
- neoplastic
- cystic fibrosis
- congestive cardiac failure / mitral stenosis
- arteriotracheobronchial fistula
- ruptured aneurysms - AAA, bronchial artery aneurysm, pulmonary artery aneurysm
- pulmonary angiodysplasia
- pulmonary hypertension
- Goodpastures syndrome
- Wegener's granulomatosis
- Behcet disease
- occupational exposures:
- isocyanate poisoning in automotive spray painters - immunologic haemorrhagic pneumonia 1)
- trimellitic anhydride–associated hemoptysis-anemia syndrome occurs after high-dose exposure to fumes
Mx of massive haemoptysis
- haemoptysis > 200mL places these patients at high risk of asphyxiation from the haemoptysis and a high mortality, especially so if the cause is a neoplasm
- iv cannula
- take bloods for FBE, U&E, LFTs, coagulation profile and DIC screen, cross match,
- oxygen to maintain SaO2
- secure airway via intubation (consider size 8.0 ETT to allow suctioning and bronchoscopy)
- may need to use selective intubation to only ventilate the non-bleeding lung
- consider placing a double lumen endotracheal tube (permits ventilation of both lungs, while preventing aspiration from one lung to another)
- CXR - generally picks up 80-90% of neoplastic causes
- correct any coagulopathy
- consider tranexamic acid (Cyclokapron)
- admit ICU
- if bleeding site is known, place pt. in the lateral decubitus position with the affected lung in the dependent position
- consider endobronchial tamponade with a Foley catheter (< 4 Fr)
- consider CT chest if stable
- urgent referral to thoracics for ?bronchoscopy
- may need catheter-directed bronchial artery embolization (BAE) or even lobectomy
Mx of non-massive haemoptysis
- could it be pulmonary embolism (PE)?
- is the patient in acute pulmonary oedema (APO)?
- does the patient need to be isolated for possible active tuberculosis (TB)?
- remember 60% will be due to infection such as acute bronchitis or pneumonia
- iv cannula, bloods for FBE, U&E, coagulation, consider D-Dimer
- CXR
- consider CT chest if CXR abnormal
- consider referral to thoracics for bronchoscopy
