Application of entropy index monitoring during recovering period of combined isoflurane and fentanyl anaesthesia / 解放军医学杂志

ABSTRACT

0.05).Furthermore,logistic regressive equations of prediction probability and RE,SE,BIS were calculated as ln [Pk/(1-Pk)]=-19.825+0.243x,ln [Pk/(1-Pk)]=-18.012+0.236x and ln [Pk/(1-Pk)]=-21.780+0.316x,respectively.From the perspective of sensitivity/specificity,RE,SE and BIS had threshold values for regaining consciousness of 83,76 and 71 with sensitivity/specificity of 0.90/0.85,0.89/0.80 and 0.88/0.78,respectively.RE was 30s earlier than BIS in predicting regaining consciousness.Conclusion Compared with BIS,entropy index seems to be a more accurate and sensitive electroencephalographic measure,and is promising in clinical application.
