The Effect of Remimazolam Versus Propofol on Postoperative Extubation Time

31. august 2026 oppdatert av: Xuyu Zhang

The Effect of Remimazolam Versus Propofol on Postoperative Extubation Time in Patients Undergoing Laparoscopic Hepatectomy: A Randomized Controlled Trial

This clinical trial aims to help us understand how two drugs, Propofol and Remazoloam, affect when researchers remove a Participants' breathing tube after liver surgery (laparoscopic liver resection).The main research questions include: comparing the time to breathing tube removal between patients who receive each drug, comparing changes in heart rate and blood pressure during surgery, and comparing the rates of unwanted medical events after surgery. Researchers will give either Propofol or Remimazolam as a sedative medicine for anesthesia. This will allow the researchers to compare the time to breathing tube removal after surgery. Participants will complete their surgery according to a pre-planned surgical plan.

Detaljert beskrivelse

This study is a clinical randomized controlled trial aimed at comparing the postoperative extubation time of remimazolam versus propofol in patients undergoing laparoscopic liver resection. Additionally, the study will compare intraoperative hemodynamic parameters, the incidence of adverse events during the anesthesia emergence period, length of stay in the post-anesthesia care unit (PACU), hospital length of stay, and the incidence of postoperative complications. Patients meeting the inclusion criteria will sign informed consent forms and be randomly assigned to one of two groups. Routine preoperative preparation will be performed. After entering the operating room, anesthesia induction and maintenance will be carried out according to the study protocol. After surgery, all patients will be transferred to the PACU. Extubation will be performed when extubation criteria are met, and patients will be returned to the ward when the Steward recovery score reaches ≥4. Data on postoperative extubation time, PACU stay, hospital length of stay, and postoperative complications will be recorded. Finally, data analysis and results reporting will be conducted.This trial can provide meaningful references for clinical drug selection. At the same time, this study will fill the gaps in clinical evidence in this field.
