Overview
The change profiles of indices derived from pEEG such as phase-amplitude coupling and bicoherence based on individual general anesthetics in children have not been examined in previous literature. Whether those indices have the abilities to predict individual drug-related anesthesia depth in children need to be explored.
Detailed description
The need to maintain a proper depth of general anesthesia during pediatric surgery is an important aspect of anesthesiology. An inappropriate anesthesia depth increases the risk of intraoperative awareness or delay in recovery in children undergoing surgery. Current modalities for anesthesia depth monitoring showed limited accuracy in children. The electroencephalogram (EEG) can be analyzed in its raw form for characteristic drug-induced patterns of change or summarized using mathematical parameters as a processed electroencephalogram (pEEG). The change profiles of indices derived from pEEG such as phase-amplitude coupling and bicoherence based on individual general anesthetics in children have not been examined in previous literature. Whether those indices have the abilities to predict individual drug-related anesthesia depth in children need to be explored.
Interventions
- Drug propofol
General anesthesia is induced and maintained mainly with propofol. - Drug sevoflurane
General anesthesia is induced and maintained mainly with sevoflurane. - Drug S-ketamine
General anesthesia is induced mainly with S-ketamine and maintained mainly with propofol.
Primary outcome measures
- phase-amplitude coupling [Time frame: induction, maintenance, and recovery of anesthesia]
- bicoherence [Time frame: induction and maintenance, and recovery of anesthesia]
- spectral analysis [Time frame: induction and maintenance, and recovery of anesthesia]
- entropy indices [Time frame: induction and maintenance, and recovery of anesthesia]
