Pneumonia Flashcards
What is pneumonia?
An infection of the alveoli
Infection -> Inflammation & Infected Fluid -> Pus/Damage/Fibrosisetc
What are the common aetiological types of pneumonia?
Community Acquired
Hospital acquired or Nosocomial
Aspiration
Atypical - Recurrent - Immunocompromised
What are the common organisms behind pneumonia?
Strep Pneumoniae
Haemophilus Influenzae
Viruses
Legionella - Mycoplasma Pneumoniae - Staph Aureus - MRSA
What radiological types of pneumonia are there?
Lobar/Segmental - Pneumonia restricted to a specific Lobe or branch
Bronchopneumonia - Diffuse pneumonia over the entire lung
What are the symptoms of pneumonia?
Malaise Fever Pleuritic Pain Dyspnoea Cough Purulent Sputum
What are the signs of pneumonia?
Affected Area: Reduced Breath sounds Bronchial Breathing Increased Vocal Resonance Stony Dullness to Percussion Reduced Chest Expansion Inspiratory Crackles
Tachypnoea/Tachycardia
Central Cyanosis
~ Low BP
What investigations can we do for pneumonia?
ABG - FBC - U+E - CRP - LFT CXR CT Bronchoscopy/Bronchoalveolar Lavage Sputum Culture & Blood Culture Throat Swab for atypical pathogens Urine Legionella antigen
What is the differential for pneumonia?
TB Lung Cancer Cardiac Failure PE Pulmonary Vasculitis
What are the complications of pnemonia?
ARDS Effusion Lung Abscess Empyema Septicaemia
What are the non-antibiotic treatments for pneumonia?
O2 -> CPAP -> Intubate/Ventilate
IV fluids
Analgesia if pleuritic pain is bad
How do we grade pneumonia?
CURB65
Confusion - Urea>7mmol/L - Resp>30 - BP D<60 or S<90 - Age>65
0 = treat in community 1-2 = hospitalise 3-5 = ITU the fuck out of them
Explain the antibiotic treatment for pneumonia?
CURB65 again!!
0-1 = Amoxicillin or Clarithromyicn or Doxycyclin
2 = Amoxillin/Levofloxacin AND Clarithromycin
3-5 = Co-Amoxiclav/Levofloxacin AND clarithromycin
(Levofloxacin if penicillin allergic)
Add Vancomycin if MRSA
Add Flucloxacillin if Staph
What are the possible outcomes of penumonia?
Resolution
Complication (mainly abscess or emphysema)
Permanent bronchiectasis
Scarring (Crytogenic Organising Pneumonia)
