1

CSF PRESSURE and composition of disease

INCREASE IN PRESSURE - due to meningitis or an increase in volume of the brain produced by edema, tumor formation, a cerebral abscess or presence of hematoma

CLOUDY FLUID usually indicates the presence of PMNs or an excessive quantity of protein

INCREASE IN WBCs wouod suggest inflammation of the meninges or encephalitis

INCREASE IN PROTEIN CONTENT implies a change in vascular permeability

2

For CSf analysis

Measure CSF pressure

Introduce therapeutic agents, anesthetics and contrast media

Usually done at L3-L4 or L4-L5

Lumbar puncture

3

Inflammation of the meninges caused by VIRAL or BACTERIAL INFECTION

VIRAL is milder and occurs more often than bacterial but bacterial type is an extremely serious illness and may result in brain damage or death

Fungi, chemical irritation and drug allergies may also cause meningitis

Meningitis

4

Symptoms of meningitis

Fever
Headache
Stiff neck
Brain swelling
Shock
Convulsions
Nausea
Vomiting

5

Bacterial CSF PATTERN IN MENINGITIS

WBC COUNT: >500-1000 (mostly PMN)

PROTEIN: high

GLUCOSE: low

6

Viral CSF PATTERN OF MENINGITIS

WBC COUNT:
