Signal Persistence of Bispectral Index and State Entropy during Surgical Procedure under Sedation
Comparison of SE and BIS parameters during EC and non-EC periods.
|EC: electrocautery, SE: state entropy, BIS: bispectral Index, EMG: electromyogram, SQI: signal quality index. SE and BIS are expressed as median (10% quartile–90% quartile). Comparisons for SE, BIS, EMG, and SQI between EC and non-EC periods were made using Mann-Whitney test. Comparison for between EC and non-EC periods was made using chi-square test with Yates correction.|
