A Phase 4 interventional study of Remimazolam and Propofol in Hemodynamic Instability, sponsored by Jun Zhang. Completed at 1 site in China. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-03-18.

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.
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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

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.
