Bispectral index and other processed parameters of electroencephalogram: an update.

Background and Objectives: The processed analysis of electroencephalogram became extremely important to monitor nervous system, being used to obtain a better anesthetic adequacy. The objective was to conduct a review about each processed parameter, defining its real importance.
Content: A review was conducted showing mathematical, physical and clinical aspects as well as their correlations and updates, presenting new integrated parameters.
Conclusions: An adequate analysis of processed parameters of electroencephalogram may provide more intraoperative safety as well as result in a better outcome for the patient.
