Which method of measurement is the gold standard for obtaining intracranial pressures?
Ventriculostomy
Fiberoptic catheter
Central line
Transcranial Doppler
The Correct Answer is A
A. Ventriculostomy is considered the gold standard for measuring intracranial pressure (ICP). This procedure involves placing a catheter into the brain's ventricles to directly measure the pressure inside the skull.
B. Fiberoptic catheter can also be used for ICP measurement, but ventriculostomy is more accurate and allows for drainage of cerebrospinal fluid if needed.
C. Central line is used for venous access, not for measuring ICP.
D. Transcranial Doppler is used to assess blood flow in the brain, but not for direct ICP measurement.
