Limited clinical improvement in pneumonia patient
?Cancer
?Alternative Organisms
?Non-infectious causes
Pneumatocele
Air filled cyst, associated with Staph A
Pneumatocele v Abscess
Abscess has air:fluid level, pneumatocele doesn’t
Pleural Effusion = Exudative
Fluid leaks OUT of the lungs due to inflammation/cancer
Exudative Pleural Effusion causes
Lung Cancer
Rheumatoid Arthritis
Pneumonia
TB
Pleural Effusion = Transudative
Fluid moves ACROSS the membrane
Transudative Pleural Effusion causes
Hypoalbuminaemia Hypothyroidism Renal failure Heart Failure Meig's Syndrome
Meig’s Syndrome
Right Pleural Effusion
Ovarian Ca
Ascites
Parapneumonic Effusion
Pleural Effusion due to pneumonia (most common cause of exudative effusion)
pH is normal
Empyema
Parapneumonic effusion progresses and enough neutrophils gather to form frank pus,
Low pH, low glucose, low neutrophils
High LDH
Asthma Chronic Management
- SABA
- SABA + Low ICS
- SABA + Low ICS + LTRA
- SABA + Low ICS + LABA
