Objectives

Narrative objectives1

Our previous study showed that two peak heights of EEG bicoherence that were calculated by bispectral analysis were decreased after incision and recovered to the previous values after 3 mcg/kg of fentanyl administration. Here we examine whether these two peak heights can be good indicators of analgesia during surgery.

Basic objectives2

Others

Basic objectives -Others

We also observe circulatory status such as blood pressure and heart rate.

Assessment

Primary outcomes

We administer fentanyl intermittently. We add some amount of fentanyl when peak heights of EEG bicoherence decrease below previously defined threshold, and compare them with those 5 minutes after fentanyl administration.
