Hypotension During Surgery

Brief summary
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
Interventions
DRUGpropofol
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.
DRUGRemimazolam
Experimental Group (Remimazolam Anesthesia Arm): Patients in this arm will receive Remimazolam as the primary anesthetic agent for inducing and maintaining general anesthesia. Remimazolam belongs to a new class of benzodiazepines and acts by enhancing the activity of GABAA receptors, leading to sedation and 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.

Masking description
In order to ensure the management of perioperative anesthesia and the safety of patients, this study is a single-blind study, that is, anesthesiologists know what kind of anesthesia they have received, and carry out anesthesia plans for patients according to groups (group P / R). Participants and postoperative evaluators will not know the grouping of patients.
Intervention model description
participants in the experimental group used remimazolam as intravenous anesthetics while participants in the control group used propofol.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Blood pressure | From enrollment to the end of treatment at 4 weeks | The primary focus is to evaluate and compare the impact of Remimazolam and Propofol on hemodynamic parameters such as blood pressure (both systolic and diastolic). The objective is to assess whether Remimazolam causes less hemodynamic fluctuation compared to Propofol during the induction and maintenance of general anesthesia. |
| Heart rate | From enrollment to the end of treatment at 4 weeks | The primary focus is to evaluate and compare the impact of Remimazolam and Propofol on hemodynamic parameters such as heart rate. The objective is to assess whether Remimazolam causes less hemodynamic fluctuation compared to Propofol during the induction and maintenance of general anesthesia. |
| Mean arterial pressure | From enrollment to the end of treatment at 4 weeks | The primary focus is to evaluate and compare the impact of Remimazolam and Propofol on hemodynamic parameters such as mean arterial pressure. The objective is to assess whether Remimazolam causes less hemodynamic fluctuation compared to Propofol during the induction and maintenance of general anesthesia. |
