Supports PI as potential noninvasive ICP surrogate in head injury; leaves open prospective validation before clinical adoption.
Does transcranial doppler registration of pulsatility index correlate with intracranial pressure and arterial pCO2 in normal subjects and head injury patients?
Noninvasive bedside transcranial doppler registration of pulsatility index correlates with intracranial pressure and may serve as a useful marker to replace invasive ICP measurement.
Homburg et al. (2009) studied this question.
