Comparison of Emergence Delirium: Remimazolam vs Sevoflurane Anesthesia

Anesthesia induction:intravenous Fentanyl 2-3 μg/kg, remimazolam 0.3-0.5 mg/kg and Rocuronium 0.6mg/kg; Maintenance of anesthesia:Remimazolam will infuse initially at a rate of 2 mg/kg/h (1-3 mg/kg/h), and remifentanil will administer at an initial infusion rate of 0.25 μg/kg/min (0.1-0.5 μg/kg/min).

Anesthesia induction: Anesthesia will induce with 8% sevoflurane in 100% oxygen at flow rate of 6 L/min, and then intravenous fentanyl (2-3 μg/kg) and rocuronium (0.6 mg/kg); Maintenance of anaesthesia: Anesthesia depth will maintain at 1-1.5 minimum alveolar concentration (MAC), and remifentanil was infuse at an initial rate of 0.25 μg/kg/min (0.1-0.5 μg/kg/min).
