chen chen Nosocomial infection

  1. Nosocomial infection (known)
    • Ventilator associated pneumonia (VAP)
    • Staphylococcus aureus
    • Methicillin resistant Staphylococcus aureus (MRSA)
    • Pseudomonas aeruginosa
    • Acinetobacter baumannii
    • Stenotrophomonas maltophilia
    • Clostridium difficile
    • Tuberculosis
    • Urinary tract infection
    • Hospital-acquired pneumonia (HAP)
    • GastroenteritisVancomycin-resistant Enterococcus
    • Legionella
  2. Ventilator-associated pneumonia (VAP)
    People on mechanical ventilation through an endotracheal or tracheostomy tube for at least 48 hours.
  3. Cause of VAP Ventilator Associated Pneumonia
    • Normally pneumoniae is caused by S. pneumoniae, H. influenzae, or S. aureus.
    • However, in the hospital the organism associated with pneumonia is most often Pseudomonas,
  4. Signs and symptoms VAP
    fever, low body temperature, purulent sputum, and hypoxia (decreasing amounts of oxygen in the blood).
  5. Diagnosis VAP
    • increasing numbers of white blood cells
    • new shadows (infiltrates) on a chest x-ray as is indicative of a pneumonia
    • Blood cultures may reveal the microorganisms causing VAP
  6. Staphylococcus aureus
    • facultatively anaerobic, gram-positive coccus and is the most common cause of staph infections.
    • nosocomial infections, often causing postsurgical wound infections.
  7. Methicillin-resistant Staphylococcus aureus
    • troublesome in hospitals, where patients with open wounds,
    • invasive devices and weakened immune systems are at greater risk of infection than the general public
  8. Acinetobacter baumannii
    • gram-negative bacterium, which is resistant to most antibiotics
    • severe pneumonia and infections of the urinary tract, bloodstream and other parts of the body.
