Emergence Delirium
Conditions
Keywords
Emergence delirium, Emergence agitation, Orientation
Brief summary
The purpose of this study is to investigate whether information of the orientation such as time, place, and patient's own name can reduce emergence delirium after general anesthesia.
Interventions
OTHERGiving orientation with headphones
During emergence, recorded voice of an investigator giving Information of orientation (time, place, patient's own name) is repeatedly played from noise-cancelling headphones
OTHEREmergence as usual with headphones
During emergence, recorded voice of an investigator calling the patient's name is repeatedly played from noise-cancelling headphones
