An observational study in Effect of Sedatives, sponsored by SMG-SNU Boramae Medical Center. Status unknown. Open to participants aged 65 Years and older. Per ClinicalTrials.gov, last updated 2020-01-30.
Sponsored by SMG-SNU Boramae Medical Center · Observational
In the present study, we observe perioperative findings of electroencephalogram in sedated and non-sedated elderly patients undergoing total knee arthroplasty under spinal anesthesia.
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.
SMG-SNU Boramae Medical Center is the lead sponsor of 38 studies on the registry; 6 are open to participants now.
