Resp, Rheum, Gastro, ID Flashcards
(132 cards)
Severe copd medication
Roflumilast = pde4 inhibitor
If FEV1<50% and >2 exacerbations in 12 months despite other meds
LTOT indications
po2 7.3-8 and one of the following:
polycythaemia
peripheral oedema (cor pulmonale)
pulmonary htn
It induces pulmonary vasodilation which improves pulmonary htn
Factors which improve copd survival
lung vol reduction surgery
stop smoking
ltot
Asthma diagnosis
feno (>50 adults, >35 child)
eosinophilia (adults only)
then once this is found then confirm with spriometry improving fev1 by 12% and 200ml or fev1 >10% predicted or if PEF variability if >20%
Complications of chest drain
surgical emphysema
post surgical reexpansion of pulmonary oedema
lung fibrosis affecting upper zones
silicosis
pneumworkers
ank spond
radiation induced
tb
allergic alveoli’s
lung fibrosis affecting lower zones
ipf
drugs
ra/sle
asbestos
xray findings of pulmonary fibrosis
patchy opacities
what type of lung cancer do you get cavitating lesions
squamous
Asbestos lung diseases
pleural plaques (benign only)
pleural thickening
asbestosis - related to length of exposure, lower lobe fibrosis (sob, clubbing, basal inspired crackles, restrictive)
mesothelioma - not related to length of exposure
remember lung cancer (not mesothelioma) is still the primary malignancy associated with asbestos
mesothelioma symptoms
sob / chest pain
dry cough
never hemopytsis
weight loss
pleural effusion
MRC scale
0 - sob only when stren ex
1 - when hurrying/walking up slight hill
2 - walks slower than most people same age or stop for breath
3 - stops for breath 100m
4 - too sob to leave house
Pneumonia vs bronchitis features
acute bronchitis has no xray changes
no focal chest signs in bronchitis but may have wheeze
no sputum, sob, wheeze normally in bronchitis
less systemic symptoms in bronchitis
Acute bronchitis mx
if crp >100 give doxy
Indication for cxr for asthma exacerbation
Indication for abg
CXR: life threatening, suspected pneumothorax, not responding to treatment
ABG: oxy <92
When to admit for asthma exacerbation
life threatening
severe if not responding to initial treatment
previous near fatal
preg
attack despite use of steroids at night
Mx for pneumothorax:
- no risks + assymp
- high risk + assymp
- no risks + symptomatic
- high risk + symptomatic
- no risks + assymp: conservative and review 2-4 days as outpatient
- high risk + assymp: monitor inpatient then follow up 2-4 weeks outpatient
- no risks + symptomatic: ambulatory device, needle aspiration, if aspiration fails then chest drain
- high risk + symptomatic : chest drain
High risk characteristics for pneumothorax
underlying lung disease
>50 + smokes
bilateral
significant hypoxia
Which lung cancer causes SIADH, cushings and Lambert eaton
SCLC
Which cancer causes hypercalcaemia, hyperthyroidism and hypertrophic pulmonary osteoarthropathy
Squamous
Which cancer causes gynaecomastia, and hypertrophic pulmonary osteoarthropathy
Adenocarcinoma
Contradindications for lung cancer surgery
