Delirium is the most common neurological complication of cardiac surgery patients and associated with poor prognosis. In recent years, the important role of quantitative electroencephalogram (qEEG) in brain function monitoring is becoming increasingly prominent. The purpose of this study is to evaluate the effect of qEEG in predictive of post-operation delirium and prognosis of cardiac surgery patients.
