Recruitment of adult patients scheduled for general anesthesia surgery with spinal subarachnoid anesthesia at Tohoku University Hospital (50 patients in total)
1) What we will do in the clinic
Perform spinal subarachnoid anesthesia and confirm that the anesthesia level necessary for surgery is obtained. 2) Perform general anesthesia before induction of general anesthesia. Before induction of general anesthesia, install a general-purpose depth-of-anesthesia monitor and begin EEG recording and depth-of-anesthesia monitoring. Induce general anesthesia with remimazolam and secure the airway. The biometric monitor and EEG data will be automatically transferred to the server in the operating room and stored. Remimazolam administration is discontinued at the end of surgery, and the patient is awakened. If the patient is not awake within 15 minutes after the administration of remimazolam, flumazenil will be administered.
(2) What will be done in this study (additional items to medical practice)
Before induction of general anesthesia, a digital EEG monitor will be additionally installed and recording will begin. The biometric monitor and EEG data obtained during general anesthesia will be stored on a personal computer. Analyze the EEG data (for research purposes). The EEG data recorded by the general anesthesia depth monitor and stored on the personal computer will be analyzed offline (frequency analysis will be performed by Bispectral Analyzer for BIS).
Validation of the general anesthesia depth monitor (for research purposes). Calculate the value of the general anesthesia depth monitor when the power of alpha and beta waves is maximum for each patient.
