NCT05130333

Brief Summary

In this study, the EEG information of patients was collected by different BIS electrodes, in order to compare the quality of EEG signals obtained by subdermal needle electrodes and the original BIS sensors, and try to use primitive EEG signals to develop a new calculation of needle electrode to monitor the depth of anesthesia.
