Treatment of pneumonia Flashcards
What is pneumonia?
A lower respiratory tract infection usually with:
- fever
- symptoms/signs in chest
- abnormal CXR
How is penumonia transmitted?
Aerosolisation
Aspiration
- micro = oropharyngeal secretions
- gross = usually anaerobes/gram -ves from GIT
Haematogenous spread
Why do aspiration pneumonias occur?
Occur in those patients who cannot protect their airways
- anaesthetised
- CVA
- under the influence of alcohol
What are the predisposing factors for pneumonia?
Elderly
Institutions (nasocomial infection)
Alcoholism
Poor nutrition
Immunocompromised
What are the symptoms of pneumonia?
Fever
Cough
Pain
SOB/dyspnoea
What are the signs of pneumonia?
Consolidation
- decreased percussion note
- increased tactile and vocal fremitus
Crackles
Bronchial breathing (harsh sounds of a blowing quantity)
What is the measurement used to score the severity of pneumonia?
CURB 65
Confusion Urea > 7 Respiratory rate > 30 Blood pressure < 90/60 > 65 years old
> 2 = admit to ITU
What investigations should be done for suspected pneumonia?
Sputum
- AFB smear (test for TB)
- MC&S (to ID organism)
Urine
- legionella antigen
- output
Blood
- MC&S
- Urea (test of kidney function)
- Serology (identify antibodies)
- WBC
ECG
Radiography
- XCR
- CT (more sensitive)
Bronchoscopy and brushing if NAD

Which antibiotics should be used for aspiration pneumonia?
Co-amoxiclav
Metranidazole
When should a pneumonia patient be admitted to ITU?
When CURB 65 > 2
What are the possible complications of pneumonia?
Lung abcess
Empyema
Bronchiectasis (abnormal widening of the bronchi + branches)
Acute respiratory distress syndrome
