Study These Flashcards
A
  • Gram -ve
  • Often occurs in patients with comorbities who are chronically ill.
  • Occurs from aspiration.
  • Often affects the lower lobe.
  • Poor prognosis.
25
Which gram -ve bacteria which often infects those with comorbidites who are chronically ill, usually via aspiration, affecting the lower lobe with a poor prognosis?
Escherichia coli
26
Describe Pseudomonas aeriginosa.
* Gram -ve * Chronically ill patients often with structural lung disease. * Produces copious amounts of very green sputum. * Gradual onset.
27
Which gram -ve bacteria causes pneumonia in chronically ill patients, often with structural lung disease, produces copious amounts of very green sputum and has a gradual onset?
Pseudomonas aeriginosa.
28
Describe Legionella pneumophilia.
* gram -ve intracellular bacteria. * Often from water or air conditioning. * Affects people who are immunosupressed. * Causes; dry cough, myalgia, acute renal failure, hepatoslenomegaly, diarrhoea, oliguria, rash, rhabdomyolysis.
29
What are the 8 symptoms of Legionella pneumophilia?
1) Rash 2) Oliguria 3) Diarrhoea 4) Acute renal failure 5) Hepatosplenomegaly 6) rhabdomyolysis 7) Dry cough 8) Myalgia
30
What is oliguria?
Oliguria is poor urine output.
31
What is rhabdomyolysis?
Breakdown of skeletal muscle.
32
What is mycoplasma pneumoniae?
``` Occurs in closed populations. Causes the following symptoms; • Arthralgias • Myalgias • Diarrhoea • Endocarditis • Meningitis • Hepatitis • Vomitting • Skin eruptions ```

It is a medical emergency, secure the airway and give IV cefuroxime.
41
What is the clinical definition of pneumonia?
Acute LRTI, usually associated with fever, symptoms and signs in the chest with an abnormal x-ray.

48
What is CURB 65?
``` Assessment system for pneumonia; C - Confusion U - Urea over >7mmol/L R - Respiratory rate greater than 30/min B - Blood pressure < 60 diastolic 65 - Over 65 ```
49
What concentration of urea scores a point on CURB 65?
>7mmol/L
50
What respiratory rate scores a point on CURB 65?
>30bpm
51
What blood pressure scores a point on CURB 65?
<60 Diastolic
52
In community acquired pneumonia what would be the management plan for a CURB 65 score of 0-1?
In community, Amoxycillin (clarithromycin if allergic to penicillin).
53
In community acquired pneumonia what would be the management plan for a curb score of 2?
Consider in-patient or supervised out patient, Amoxycillin PLUS clarithromycin.
54
In community acquired pneumonia what would be the management plan for a curb score of 3+?
* Severe Pneumonia! * Consider HDU * IV augmentin and p.o. clarithromycin.
55
What would the management of 'atypical' pneumonia be?
* I.V. Clarithromycin | * I.V. Rifampicin
56
If cavitation occurred with pneumonia what would the management plan be?
* I.V. cefuroxime * I.V. Metronidazole * I.V. Flucloxacillin
57
What would the management be for aspiration pneumonia?
* I.V. Cefuroxime | * I.V. Metronidazole
58
What are the five main complications of pneumonia?
1) Abscesses 2) Bronchiectasis 3) Empyema 4) ARDS 5) Pulmonary emboli
