title: Unusually low bispectral index values during emergence from anesthesia.
abstract: We observed unusually low BIS values during emergence from anesthesia apparently caused by misanalysis (as "suppression") of low voltage electroencephalogram.
  
  
  CONCLUSIONS
  When BIS values do not adequately correspond with clinical status, it is necessary to check raw electroencephalogram waveforms to more clearly characterize patient status.
