Currently, a lot of equipments based on Bispectral index (BIS) is used clinically in order to measure the depth of anesthesia. Although BIS is used for the measurement of the presence of consciousness or degree of sedation during general anesthesia, it could be influenced by factors that affect or interfere with the activity of EEG because it is a numerical value which is measured by analyzing EEG. The BIS electrode for EEG analysis should be attached to the patient's forehead and the EEG signal is 0.5 - 30 Hz, the EMG signal is 30 - 300 Hz, and the BIS analyzes the 0 - 47 Hz signal. Therefore, 30 -47 Hz EMG signal may influence the BIS value and the BIS value may differ from the actual. In patients with complete muscle relaxation, the change in BIS varies in proportion to the concentration of anesthetic, but in a state with less muscle relaxation or arousal period of anesthesia when recovery of muscle relaxation occurs, BIS value may not accurately reflects the change in the depth of anesthesia. Although there is a study on the influence of the degree of muscle relaxation on BIS value, there is no study on whether phase lag entropy (PLE) measuring anesthesia depth based on different mechanism from BIS is affected by status of muscle relaxation. After measuring BIS and PLE at the same time, I will compare both of them and investigate the reliability of the measurement of the depth of anesthesia of PLE and how electromyogram activity affects PLE.

Primary | The difference of phase lag entropy between before and after neuromuscular recovery | PLEM 100 is 4-channel electroencephalogram (EEG) monitor and it records electric activity signals of the brain generated from the human body. The anesthesiologist administers sugammadex intravenously at the end of the surgery, and then monitors and records the values of BIS, PLEM 100, and neuromuscular monitoring in 1 minute increments for 5 minutes until neuromuscular recovery is completed. | 24 hours | |
Secondary | The difference between BIS and phase lag entropy during general anesthesia | BIS uses the frequency, amplitude, phase angle of electroencephalogram, and measures the coherence. Finally, it is closely related to the level of sedation and consciousness by the anesthetic agent. PLEM 100 is 4-channel electroencephalogram monitor and it records electric activity signals of the brain generated from the human body. The anesthesiologist continuously monitor the state of consciousness and muscle relaxation from entrance of the patient to the complete recovery of muscle relaxation. | 24 hours |
