About

This study is a randomized controlled trial designed to investigate the effects of two anesthetics, remimazolam and propofol, on intraoperative hemodynamics in patients undergoing laparoscopic liver resection. The experimental group receives remimazolam, while the control group receives propofol. The primary objective is to compare the hemodynamic responses of patients in both groups during the surgical procedure, aiming to provide insights into the potential differences in cardiovascular stability and anesthetic management associated with these two drugs

88 participants in 2 patient groups

Experimental Arm: Remimazolam Group

Experimental group

Description:

Experimental Group (Remimazolam Anesthesia Arm): Patients in this arm will receive Remimazolam as the primary anesthetic agent for inducing and maintaining general anesthesia. The specific dosing regimen and administration protocol for Remimazolam will be determined based on the patient's characteristics and the surgical procedure being performed. Close monitoring of the patient's vital signs, particularly hemodynamic parameters, will be conducted throughout the anesthesia period to ensure safety and efficacy.

Treatment:

Drug: Remimazolam

Control Arm: Propofol Group

Active Comparator group

Description:

Control Group (Propofol Anesthesia Arm): Patients in this arm will receive Propofol as the primary anesthetic agent for general anesthesia. Propofol is a well-established anesthetic drug commonly used in clinical practice for its rapid onset and short duration of action. Similar to the experimental group, the dosing regimen and administration protocol for Propofol will be tailored to the individual patient's needs and the surgical procedure. Hemodynamic stability and other vital signs will also be closely monitored in this group to assess the safety and effectiveness of Propofol in comparison to Remimazolam.

Treatment:

Drug: propofol
