Performance of EEG During Emergence Agitation in Nasal Surgery.

The purpose of the study is to evaluate the relationship between perioperative electroencephalogram and emergence agitation in the nasal surgery. Previous studies showed that low frequency band wave activity increased during emergence delirium in pediatric patients. It is still not enough to explain the relationship between emergence agitation and electroencephalogram in adults. Researchers will demonstrate the relationship between parameters related electroencephalogram and emergence agitation in adults undergoing nasal surgery.

Inclusion Criteria:Adult patients aged 19-55 years who are undergoing nasal surgery under general anesthesia using inhalational agentExclusion Criteria:CNS disease (ex.dementia, stroke, brain tumor, psychological disorder..)unable to communicategeneral anesthesia history within 6 monthsdisagree to participate in study
