Summary

Cerebral autoregulation (CA) is the property of the cerebral vascular bed to maintain cerebral perfusion in the presence of changes in blood pressure. In the case of anesthesia, altered cerebral autoregulation, including altered carbon dioxide and hemodilution, can impair physiological changes in the body and lead to poor postoperative prognosis. As a novel ultra-short-acting benzodiazepines drugs, remimazolam has been accepted for induction and maintenance of clinical anesthesia. Compared to the traditional benzodiazepines drugs, remimazolam combines the safety of midazolam with the effectiveness of propofol, and also has the advantages of acting quickly, short half-life, no injection pain, slight respiratory depression, independent of liver and kidney metabolism, long-term infusion without accumulation, and has a specific antagonist: flumazenil. Our study aimed to investigate the different effects of remimazolam and propofol on dynamic cerebral blood flow autoregulation function during general anesthesia.
