The Comparison of Hemodynamic Effects Between Remimazolam-remifentanil and Propofol-remifentanil in Patients Undergoing Laparoscopic Cholecystectomy

During induction, the propofol group starts the effect site concentration at 4.0 ng/ml with TCI and adjusts it to around 3.0 \~ 4.0 ng/ml after intubation to maintain an appropriate EEG-based depth of anesthesia.

In the remimazolam group, start remimazolam at 6 mg/kg/hr and adjust it to 1 mg/kg/hr after loss of consciousness to maintain an appropriate EEG-based depth of anesthesia.
