ARX-Derived Auditory Evoked Potential Index and Bispectral Index During the Induction of Anesthesia with Propofol and Remifentanil

Abstract

The modern electroencephalographic ARX-derived auditory evoked potential index and the bispectral index were superior to the classic electroencephalographic and hemodynamic variables for predicting anesthetic conditions. Variables derived from the auditory evoked potential did not provide an advantage over variables derived from spontaneous electroencephalogram.
