Syndrome of intracranial hypertension and hypotension/Repetitorium
From WikiLectures
Presumed terms: factors determining intracranial pressure, pressure-volume curve
Intracranial hypertension[edit | edit source]
Up to 15 torr compensated state, above 20 torr CPP threat.
Causes[edit | edit source]
- intracranial expansion (traumatic, tumor)
- brain edema
- hemodynamic swelling of the brain (vasodilatation)
- CSF accumulation (increased secretion, decreased resorption)
Symptoms[edit | edit source]
- clinical trias : headache, vomiting, congestion on the fundus of the eye
- sleepiness, memory disorders
- dizziness
- bearing symptoms
- bradycardia
- cones: occipital, temporal
- hydrocephalus without hypertension in children
Therapy[edit | edit source]
- surgical (reduction of intracranial expansion x increase of intracranial space)
- hyperventilation
- osmotherapy (intact HEB)
- diuretics
- hypothermia
- positioning
Intracranial hypotension[edit | edit source]
Symptoms similar to intracranial hypertension, but improves when lying down
Causes[edit | edit source]
- decreased secretion of cerebrospinal fluid
- increased resorption of cerebrospinal fluid
- CSF leak (trauma, lumbar puncture)
