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]

  1. intracranial expansion (traumatic, tumor)
  2. brain edema
  3. hemodynamic swelling of the brain (vasodilatation)
  4. 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]

  1. decreased secretion of cerebrospinal fluid
  2. increased resorption of cerebrospinal fluid
  3. CSF leak (trauma, lumbar puncture)
