Brief summary

The goal of this randomized controlled trial is to compare total intravenous anesthesia with remimazolam vs total intravenous anesthesia with propofol in moderate-to-high risk patients undergoing major elective noncardiac surgery under general anesthesia. The primary hypothesis is that total intravenous anesthesia with remimazolam can increase days alive and out of hospital at postoperative day 30 compared with total intravenous anesthesia with propofol.

Interventions

DRUGRemimazolam

Remimazolam is administered intravenously for induction and maintenance of general anesthesia.

DRUGPropofol

Propofol is administered intravenously for induction and maintenance of general anesthesia.

Quality of Recovery-15 score on the first day after surgeryPostoperative day 1Using Quality of Recovery-15 questionnaire to evaluate the quality of perioperative recovery. Quality of Recovery-15 consists of 15 comprehensive questions, including physical comfort (5 items), psychological support (2 items), physical independence (2 items), emotional state (4 items), and pain (2 items), each item is scored with 0-10 points, 0 represents poor state, 10 represents good state, and the total score is the Quality of Recovery-15 score of the patient.
