Bispectral Index, Monitored Anesthesia Care
Conditions
Brief summary
The investigators will evaluate the effect of bispectral index-guided titration of sedation during ear surgery under monitored anesthesia care on participant's satisfaction with anesthesia, as well as side effects caused by the anesthetics.
Interventions
DEVICETitration under the guidance of BIS
The infusion rate of dexmedetomidine is increased by 0.1mcg/kg/h if BIS is greater than 80; The infusion rate is decreased by 0.1mcg/kg/h if BIS is less than 60.
DIAGNOSTIC_TESTTitration under the guidance of OAA/S
The infusion rate of dexmedetomidine is increased by 0.1mcg/kg/h if OAA/S is greater than 3; The infusion rate is decreased by 0.1mcg/kg/h if OAA/S is less than 3.
