The Effect of General Anesthesia with Remimazolam and Propofol on Rhythmic State and Cognitive Function
Sponsor: The Second Affiliated Hospital of Chongqing Medical University
Summary
This study want to observe the effects of remimazolam and propofol for general anesthesia on postoperative rhythm and cognitive function. The observation group was given remimazolam for general anesthesia, and the control group was given propofol for general anesthesia. Both drugs are commonly used as intravenous anesthetics for general anesthesia and have been shown to be safe for use in general anesthesia. The investigators hope can understand the effects of remimazolam and propofol for general anesthesia on rhythm status and cognitive function through this study, further reduce the occurrence of postoperative cognitive function impairment, and enable subjects to better recover.

Interventions
Remimazolam
Remimazolam 6mg/kg/h was pumped intravenously for 2.5 min, Sufentanil 0.5 μg/kg and rocuronium 0.6mg/kg were injected intravenously, and endotracheal intubation was performed 3 minutes later. Remimazolam was then pumped at 1 mg/kg/h, the BIS was kept in the range of 40-60 through general anesthesia, and the remimazolam infusion rate was adjusted (0.5-3 mg/kg/h).If the BIS cannot be maintained at ≤ 60 or there are signs of potential inadequate anesthesia (such as cough, sweating, and patient movement), and the maximum infusion dose of remimazolam has been given, supplemental sedation with the remedial drug sevoflurane or propofol is used and the case is dismissed.
propofol
Propofol (2-3mg/kg), Sufentanil (0.5μg /kg), rocuronium (0.6mg/kg) were injected intravenously, and endotracheal intubation was performed for 3 minutes. Subsequently, propofol was pumped at 4-10mg/kg/h to maintain the BIS in the range of 40-60.
