EEG Circadian Variation of ICU Patients Clinical Trial
The investigators propose to evaluate circadian variation of EEG using BIS (bispectral index) monitor in ICU patients in three different groups: non-sedated, only sedated and sedated and curarized. BIS monitor values as SR (suppression rate), SEF (Spectral edge frequency), bispectral index and EMG (electromyography) during 24 hours in admitted patients except acute neurological disease.
