Flashcards in Bronchiectasis Deck (9)
What is it?
Bronchectasis is irreversible dilatation of the bronchi causing increased susceptibility to chronic infection
Where can the bronchi are affected?
Anywhere beyond the supportive rings of cartilage
What can cause bronchiecstasies? Name 3
Cystic fibrosis, pneumonia, primary TB, inhaled foreign body, bronchial tumours, reactivated TB
The dilated airways become lined with granulation tissue (neutrophils etc), epithelia becomes damaged and inflamed, inflammation and fibrosis of deeper layers of the bronchial walls and hyper trophy of bronchial arteries
What are the clinical features of bronchectasis?
Chronic productive cough worse in the mornings and brought on by posture changes, pneumonia, pleurisy, haemoptysis, low grade fever, clubbing, anorexia
Sputum culture (pseudonomas, fungi such as aspergillus, mycobacteria), CXR (in advanced disease only), high resolution CT (shows thickened dilated airways), ciliary function test (use saccharine droplet in nose and time till taste it)
Physiotherapy and antibiotics (same as those in COPD in larger and longer doses) and in some cases surgical excision of bronchi ecstatic area I.e. One lobe affected only
Progressive and culminates in respiratory failure if associated with ciliary dysfunction or cystic fibrosis. If not the quite good if given aggressive antibiotic therapy and physiotherapy often
