Resp Flashcards
Bronchiectasis
Medications & Management?
Differentials for basal crepitations
Lower zone interstitial lung disease / pulmonary fibrosis
Bronchiectasis - clear on coughing
Pulmonary oedema
Causes of ILD/Pulmonary fibrosis
Upper zone:
* Silicosis
* Tuberculosis
* Ank Spond, sarcoidosis
* ABPA, Extrinsic allergic alveolitis
* Radiation
Lower zone:
* Asbestosis
* Rheumatoid arthritis, SLE, scleroderma, Sjogren’s
* Idiopathic pulmonary fibrosis
* Drugs - MTX, amiodarone
ILD: Definitive Ix?
High resolution CT scan
* Honeycombing
* Reticular shadowing
* Ground glass
* Volume loss
ILD: Management
Conservative
* Smoking cessation
* Remove causative allergen/medication (if applicable)
* Pulmonary rehabilitation
* Claim compensation e.g. asbestos
* Vaccines
Medical:
* Tx underlying cause
* Manage complications - Abx for infective exacerbations
* Steroids
* Immunosuppressants e.g. azathioprine
* Antioxidants e.g. NAC
* Pirfenidone - anti fibrotic
* Long term O2 therapy
Surgical:
* single/double lung transplant
Signs of Right HF
Hepatomegaly, ascites
Peripheral oedema
Raised JVP
Criteria for steroid Tx in sarcoidosis
Pulmonary fibrosis - symptomatic stage 2/3 +
Uveitis
Neurological involvement
Cardiac - constrictive pericarditis?
Hypercalcaemia
Management of scleroderma
Conservative
- Currently no cure: psychological?
- monitor BP, renal function, annual echo, spirometry
Medical
- immunosuppressive regimes: IV Cyclophosphamide (organ involvement, progressive skin disease)
- Anfibrotic tyrosine kinase inhibitor
- ACEi, ARB (prevent renal crisis)
Bronchiectasis radiological findings
Signet ring
Tram line and ring shadows (thickened bronchial walls)
Bronchiectasis Ix
Sputum: culture
CXR/HRCT
Specialist
Spirometry: obstructive
Bronchoscopy - locate site of haemoptysis, exclude obstruction, obtain samples for culture
Serum immunoglobulins
CF sweat test
Aspergillus precipitins
Skin prick RAST, IgE
Management of bronchiectasis
Conservative
- smoking cessation
- physio: airway clearance
Medical
- mucolytics
- Abx (oral ciprofloxacin)
- more than 3 exacerbations = prophylactic Abx
Surgery
- control localised disease or severe haemoptysis
Management of stable COPD
Conservative
- smoking cessation
- pulmonary rehab
- flu, pneumococcal vaccines
Medical
1. SABA / SAMA
2a. NO Evidence of steroid responsive? LABA + LAMA
2b. Evidence of steroid responsiveness? LABA + ICS
3. Still Sx? Triple therapy (LAMA + LABA + ICS)?
4. Specialist
- LTOT
- Prophylactic Abx: criteria???
Surgical
- Lung volume reduction, transplant
- indications: recurrent pneumothoraces, isolated bullous disease
Indications for LT O2 therapy
Clinically stable non smoker on maximum medical Tx
PaO2 <7.3 on 2 occasions 3 weeks apart
OR PaO2 7.3-8.0 and pulmonary HTN, polycythaemia, peripheral oedema, nocturnal hypoxia
Indications for specialist referral
Uncertain diagnosis, suspected severe COPD, rapid decline in FEV1
Cor pulmonale
Bullous lung disease (assess for surgery)
Assessment for oral steroids, nebuliser, LTOT
<10 yr pack history OR age <40yo
Sx disproportional to LFT
Frequent infections (exclude bronchiectasis)
Paraneoplastic syndromes in lung cancer
Small cell
- SIADH
- ACTH: Cushing’s syndrome
- Lambert Eaton
Squamous
- PTH-rp
Adenocarcinoma
- hypertrophic pulmonary osteoarthropathy
- gynaecomastia
