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.

Developmental phase
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.
