简要总结
The investigators want to compare the performance of anesthetic depth monitoring for sedation (ADMS) to the bispectral index (BIS) as electroencephalographic measures of sevoflurane effect using two combined sigmoidal Emax models via population pharmacodynamic approach.
详细描述
Intraoperative awareness under general anesthesia is rare, but it may cause serious psychological sequelae. Anesthetic depth monitoring system based on electroencephalography(EEG) or evoked potential are broadly used methods. Bispectral index (BIS) monitor is most popular anesthetic depth monitoring system. Anesthetic depth monitoring for sedation (ADMS) is developed in Korea as an electroencephalographic monitor for measuring the depth of anesthesia. The investigators want to compare the performance of ADMS to the bispectral index (BIS) as electroencephalographic measures of sevoflurane effect using two combined sigmoidal Emax models via population pharmacodynamic approach.

结局指标
主要结局
Bispectral Index (BIS)
时间窗: Data capture will be started 45 minutes after induction of general anesthesia for 70 minutes
captured BIS data (0\~100) from the BIS system after induction of general anesthesia, sevoflurane concentrations will be progressively increased and then decreased over 70 min.
Anesthetic depth monitoring for sedation (ADMS)
时间窗: Data capture will be started 45 minutes after induction of general anesthesia for 70 minutes
captured ADMS data (0\~100) from the ADMS system after induction of general anesthesia, sevoflurane concentrations will be progressively increased and then decreased over 70 min.
次要结局
- Adverse events(visit patients 24 hours after operation.)
