About this study
Official title: Effect of Remazolam on Hemodynamics During Hepatectomy Under General Anesthesia Combined With Thoracic Epidural Anesthesia
There is high incidence of hemodynamic instability in patients undergoing hepatectomy with low central venous pressure, especially in general anesthesia combined with epidural anesthesia. Remazolam, a new benzodiazepine, has no significant cardiovascular inhibitory effect. Investigators hypothesis that remazolam will provide better hemodynamic when compared with propofol in patients undergoing hepatectomy with general anesthesia combined with epidural anesthesia.
Read the detailed description
Investigators plan to adopt the following strategies in the clinical study of this project: (1) To compare remazolam and propofol during anesthetic induction and maintenance; (2) Remazolam group: remazolam is administered 0.3mg/kg intravenous for anesthesia induction. Propofol group: propofol is administered 2mg/kg intravenous for anesthesia induction; (3) Epidural analgesia is used during perioperative period, and remifentanil pump injection is used during the operation to assist the subjects to tolerate the tracheal catheter; (4) the haemodynamic instability score (Hemodynamic instability score) is used to comprehensively evaluate intraoperative hemodynamic status. (5) To evaluate the incidence of postoperative complications. Through the above strategies, investigators further determine the optimization effect of remazolam, a novel benzodiazepine drug, on intraoperative hemodynamics in patients undergoing low central venous pressure hepatectomy, and further lay an empirical foundation for the routine use of remazolam in clinical hepatectomy.

What is being measured
The primary outcome is the main question the study is designed to answer.
Hemodynamic instability score
The hemodynamic instability score is calculated as a weighted continuous measure ranging from 0 to 160 points, intended to reflect deviations of blood pressure and heart rate from predefined thresholds, and infusion rates of vasoactive agents and fluids.
Measured: intraoperative

Cardiac index （CI）
The parameter of CI is measured by advanced hemodynamic monitoring device.
Measured: intraoperative
Stroke volume variation (SVV)
The parameter of SVV is measured by advanced hemodynamic monitoring device.
Measured: intraoperative

Remazolam, a new benzodiazepine, has no significant cardiovascular inhibitory effect. Investigators hypothesis that remazolam will provide better hemodynamic when compared with propofol in patients undergoing hepatectomy with general anesthesia combined with epidural anesthesia.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hemodynamic instability score (time frame: intraoperative). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06565715, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Mar 2025; AzTrials last refreshed its copy on 7 Nov 2026.
