title: [Relationship between seizure duration and bispectral index during modified electroconvulsive therapy].
abstract: BACKGROUND
  The relationship between seizure duration and bispectral index (BIS) has not been studied well in modified electroconvulsive therapy (mECT).
  
  
  METHODS
  We studied the changes in BIS and recorded the seizure duration during mECT under propofol and suxamethonium anesthesia. We examined the relationship between seizure duration and BIS.
  
  
  RESULTS
  The BIS value immediately before turning on the electricity correlated with seizure duration. The range of BIS values that caused effective seizure duration were 53.6-58.8.
  
  
  CONCLUSIONS
  Our study shows the possibility of determining the moment of application of electricity in mECT by using BIS values.
