The relationship between memory and bispectral index, auditory evoked potential index, effective-site concentration during sedation with propofol by TCI / 中华麻醉学杂志

ABSTRACT

effect-site concentration. The cutoff points of BIS index, AEPI and effect-site concentration for implicit memory were 47, 28 and 2.3 ?g ? ml-1 respectively.Conclusion Implicit memory exists in unconscious patients when there is no noxious stimulation. Implicit memory disappears at level 1 of OAA / S score. Implicit memory score correlates well with BIS index, AEPI. The BIS index, AEPI and effect-site concentration are good predictors of implicit memory during target-controlled infusion of propofol.
