title: Bispectral index and other processed parameters of electroencephalogram: an update.
abstract: OBJECTIVE
  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.
  
  
  BACKGROUND
  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.
