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

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

This study is conducted to determine whether the occurrence of hypotension is reduced by the combined use of remimazolam and remifentanil compared to the conventional combination use of propofol and remifentanil. Patients enrolled in the study are infused continuously with either propofol or remimazolam from the start of anesthesia to the end of surgery.
