| Research Abstract |
The purpose of this study was to research the methods for quantifying the intraoperative pain by evaluating changes in cerebral functions due to noxious stimulation. Auditory evoked potential (AEP) index derived from changes in midlatency AEP and bispectral index (BIS) derived from spontaneous electroencephalogram were measured during noxious stimuli under general anesthesia. Tracheal intubation, surgical incision of the skin, and electroconvulsive therapy did not alter both AEP index and BIS.
