BRONCHIECTASIS Flashcards
Define bronchiectasis
Chronic infection of the bronchi and bronchioles leading to permanent dilatation of the airways. The airways become filled with mucus which can lead to an obstructive pattern.
What are the main organisms that can cause the chronic infections in bronchiectasis?
H. influenzae
S. pneumoniae
S. aureus
P. aeruginosa
What are the congenital causes of bronchiectasis?
Cystic fibrosis
Young’s syndrome
Primary ciliary dyskinesia (approx half of these patients will have Kartagener’s syndrome)
What would a patient with suspected bronchiectasis typically present with? (Name 3 symptoms)
Persistent cough
Copious purulent sputum
Intermittent haemoptysis
What signs would typically be detected in a patient with suspected bronchiectasis? (Name 3 possible signs)
Finger clubbing
Coarse inspiratory crepitations
Wheeze
What might be seen on x-ray of a patient with bronchiectasis?
Marked abnormal dilatation of the airways
This may be in one lobe or widespread
There may be cystic shadows, indicating that this patient may have cystic fibrosis
What tests and investigations would be ordered to confirm a diagnosis of bronchiectasis?
Chest X-ray
CT scan or even High Resolution CT (HRCT)
Sputum culture
Spirometry - often shows an obstructive pattern
Bronchoscopy - locate site of haemoptysis
What are the management options for a patient with confirmed bronchiectasis?
Postural drainage - literally inclining the body so that the trachea is below the affected lobe to clear the airway. This should be accompanied by chest physiotherapy.
Antibiotics - prescribed according to bacterial sensitivities.
Bronchodilators - useful in patient with co-morbidities such as asthma, COPD and Allergic Bronchopulmonary Aspergillos (ABPA)
Corticosteroids eg prednisolone - for patients with ABPA
What are the possible complications of bronchiectasis? (Name at least 3)
Pnuemonia Pleural effusion Pneumothorax Haemoptysis Cerebral abscess Amyloidosis
What are the non-congenital causes of bronchiectasis? (Name at least 4)
Post-infection Bronchial Obstruction Allergic Bronchopulmonary Aspergillos (ABPA) Hypogammaglobulinaemia Rheumatoid Arthritis (RA) Ulcerative colitis Idiopathic
Characteristic feature on Chest X ray?
Thickened bronchial walls
- tramlines and signet rings
