Q

What is COPD?

A

Chronic obstructive airways disease
Limited reversibility
Combination of bronchitis and emphysema

Abnormal inflammatory response in airways leads to mucus hypersecretion and chronic tissue destruction –> remodelling –> fibrosis –> increased airway resistance

Commonest cause = cigarette smoking
Also consider alpha 1 antitrypsin deficiency and occupation (e.g. coal mining)

- Reduce rate of exacerbations
- Indicated if >3 exacs requiring steroids or 1 exac requiring hospitalisation / year

Reduction of Lung volume (surgery)

Inhalers
- SABA/LABA +/- ICS +/- LAMA

Smoking Cessation

Correction of spontaneous primary pnemothorax

Pleurodesis

Wedge resection

Q

Benefits of VATs as opposed to “traditional” thoracic surgery

A

Minimally invasive
- Reduce need for muscle division & rib spreading/fractures

Quicker recovery
Reduced length of stay in hospital
Earlier mobilisation
Lower doses opiates/analgesics required

All adds up to reduce risks associated with hospital admissions e.g. HAI, delirium

76
Q

Indications for Lung Transplant

A

ILD
Advanced COPD (usually single)
CF
Emphysema secondary to alpha1AT
Pulmonary HTN

Single = if >65 years old
Double = <60 years old

CRITERIA
- >50% chance of death within 2 years if no transplant
- >80% chance of survival >90 days
- >80% chance of 5yr survival

77
Q

Contraindications for Lung Transplant

A

Severe organ dysfunction e.g. cardiac failure

Acute Critical Illness

Severe malnutrition/obesity

Smoking in last 6 months

Malignancy in last 5 years

Poor exercise tolerance/unable to walk

78
Q

What is a Bullectomy?

A

= removal of giant bullae

Can help improve symptoms and lung function (restores mechanical linkage between chest wall and lungs)

Indications
1) Progressive SoB despite maximal Rx
AND
2) FEV1<50%
AND
3) Bullae>1/3 of hemithorax

79
Q

What is Cor Pulmonale?

A

= enlargement and failure of right side of heart due to increased vascular resistance secondary to respiratory disorder e.g. COPD

Fluid retention & pulmonary HTN –> increased strain on RV –> RV failure

Best treatment = prevention!

Will likely need LTOT & diuretics

80
Q

Signs of Bronchiectasis

A

Oxygen therapy
Sputum pots
Inhalers

Likely young if CF

Wet cough, ?cachexia

Clubbing, ?yellow nails

Midline/central line/portacath (?long term abx therapy)
?lymphadenopathy
Non deviated trachea

Coarse crackles
?Scars from previous lobectomy/wedge resection

81
Q

COPD Spirometry Diagnostic Values

A

FEV1/FVC < 0.7

Severity:
FEV1 0.8 - 1.0 = mild
FEV1 0.5 - 0.8 = moderate
FEV1 0.3 - 0.5 = severe
FEV1 <0.3 = very severe
