Use of cerebral state index to predict long-term unconsciousness in patients after elective craniotomy with delay recovery

摘要

BackgroundThe major difficulty in postoperative care in patients after craniotomy is to distinguish the intracranial deficits from the residual effect of general anesthesia. In present study, we used cerebral state index (CSI) monitoring in patients after craniotomy with delayed recovery, and evaluated the prediction probability of CSI for long-term postoperative unconsciousness.
