简要总结
In the present study, we observe perioperative findings of electroencephalogram in sedated and non-sedated elderly patients undergoing total knee arthroplasty under spinal anesthesia.
详细描述
In the present study, we observe perioperative findings of electroencephalogram in sedated and non-sedated elderly patients undergoing total knee arthroplasty under spinal anesthesia. Electroencephalogram is performed before, during, and 1 day after surgery. After the induction of anesthesia, sedation is performed according to the patient's request. If a patient want to be sedated during surgery, one of the three sedatives (dexmedetomidine, propofol, and midazolam) is administered.
