Clinical Trial Summary

This study is a randomized controlled trial to evaluate whether EEG-guided calibration of inhalation agents can reduce occurrence of EEG discontinuity in infants during general anesthesia.


Description:

This is a study for comparison of incidence of EEG discontinuity during general anesthesia using sevoflurane. EEG guidance group will receive calibration of fraction of inhalational sevoflurane according to components of slow wave and delta wave of raw EEG. Control group will receive conventional management of anesthesia according to vital signs.

Study Design


Intervention

Procedure:
EEG guided anesthesia
Monitoring of electroencephalogram via Sedline probe by MASIMO corporation. Adjust concentration of inhalational sevoflurane during anesthesia, according to component of slow&delta wave and alpha wave, so that slow/delta oscillation (with or without alpha oscillation) is maintained.
Conventional anesthesia
Adjust concentration of inhalational sevoflurane during anesthesia, according to vital signs, so that mean blood pressure and heart rate are maintained between 80% and 120% of baseline values measured at ward before anesthesia.
