A new method of intracranial pressure monitoring by EEG power spectrum analysis.
OBJECTIVE
To investigate the feasibility of Electroencephalogram (EEG) power spectrum analysis as a noninvasive method for monitoring intracranial pressure (ICP).


METHODS
The EEG signals were recorded in 62 patients (70 cases) with central nervous system (CNS) disorders in our hospital. By using self-designed software, EEG power spectrum analysis was conducted and pressure index (PI) was calculated automatically. Intracranial pressure was measured by lumbar puncture (LP).


RESULTS
We found a significant negative correlation between PI and ICP (r = -0.849, p < 0.01).


CONCLUSIONS
The PI obtained from EEG analysis is correlated with ICP. Analysis of specific parameters from EEG power spectrum might reflect the ICP.
