Overview
Brief Summary
Remimazolam, a novel ultra-short acting benzodiazepine that combined the advantages of midazolam and remifentanil, has been developed for procedural sedation, induction and maintenance of general anesthesia, and sedation in the ICU. Previous studies have suggested that efficacy and safety of remimazolam are not inferior to propofol or midazolam in patients undergoing colonoscopy,bronchoscopy and some other treatments. However, the efficacy and potential adverse effects of remimazolam on patients undergoing endovascular procedures of cerebrovascular disorders is still unclear. In this study, we tend to conduct a single-center, randomized, single-blind ,non-inferiority trial to compare the efficacy and safety of remimazolam and propofol in endovascular procedures of cerebrovascular disorders.

Arms & Interventions
Remimazolam
In remimazolam group, a 0.1 mg/kg dose of intravenous remimazolam was administered for induction, and 0.3-0.7 mg/kg/h infusion for maintenance after intubation.
Intervention: remimazolam
Propofol
In propofol group, a 2 mg/kg dose of intravenous propofol was administered for induction, and 4-12 mg/kg/h infusion for maintenance after intubation.
Intervention: propofol
