Pneumonia Flashcards
What if pneumonia?
Acute LRTI associated with fever, chest symptoms and CXR abnormalities.
What typical organisms cause pneumonia in CAP?
• Haemophilus influenzae
• Moraxella catarrhalis
Streptococcus pneumoniae
What atypical organism cause pneumonia in CAP?
• Mycoplasma • SA • Legionella Chlamydia Klebsiella
Can get fungal e.g. PCP in HIV
What organisms tend to cause HAP?
• Gram negative enterobacteria
Staph aureus
What kind of patients can get aspiration pneumonia
patients with strokes, myasthenia, bulbar palsies, decreased consciousness, oesopophageal disease. Usually causes a right sided middle lobe pneumonia.
What are symptoms of pneumonia?
- Fever
- Rigors
- Malaise
- Anorexia
- SOB
- Cough
- Purulent sputum
- Pleuritic pain
What are signs of pneumonia?
• Pyrexia • Cyanosis • Confusion • Tachypnoea • Tachycardia Hypotension
What are signs of consolidation in respiratory exam?
Reduced expansion, dull percussion, ↑tactile vocal fremitus/vocal resonance, bronchial breathing), and a pleural rub.
What investigations in pneumonia?
O2 sats
ABG (is sats <92)
Bloods: CRP, WCC, urea, and cultures
Sputum cultures + microscopy
Urine if legionella suspected
Pleural fluid sample if effusion
What is scoring system for pneumonia?
CURB 65
• Confusion (abbreviated mental test ≤8)
* Urea >7mmol/L * Respiratory rate ≥30/min * BP <90 systolic and/or 60mmHg diastolic) * Age ≥65.
0–1, PO antibiotic or home treatment
2, hospital therapy
≥3, severe pneumonia indicates mortality 15–40%—consider ITU. Other features increasing the risk of death are: comorbidity; bilateral/multilobar; PaO2 <8kPa.
What is antibiotic treatment for pneumonia? (typical organisms)
Usually oral amoxicillin or clari or doxy (CURB 0-1) 5 days
Oral or IV amoxicillin + clari or doxy 7 days (CURB 2)
CO-amoxiclav or cephalosporin and clari if CURB >3
What other treatments for pneumonia?
O2
IV fluids
VTE prophylaxis
Analgesia if pleurisy
What are complications of pneumonia?
Respiratory failure
Hypotension (sepsis)
AF
Pleural effusion and empyema (Suspect in patients with a resolving pneumonia but recurrent fever. Pleural fluid is yellow and turbid with pH <7.2, low glucose, raised LDH
Lung abscess
Septicaemia
