Brief Summary

Intraoperative hypotension is common during major noncardiac surgery and is associated with adverse postoperative outcomes. Propofol, the most commonly used intravenous anesthetic agent worldwide, is associated with hypotension on induction and maintenance of general anesthesia. Remimazolam is a newly developed short-acting benzodiazepine drug and has been approved for use in procedural sedation and general anesthesia. It was associated with a lower incidence of hypotension during procedural sedation in previous studies. The aim of this study is to tested the primary hypothesis that total intravenous anesthesia with remimazolam reduces the duration and severity of hypotension during major noncardiac surgery compared with total intravenous anesthesia with propofol.

Outcome Measures

Primary Outcomes (1)

  • Time-weighted average (TWA) intraoperative mean arterial pressure (MAP) under 65 mmHg.

    TWA-MAP under 65 mmHg for each patient is derived by dividing area under the curve (AUC)-MAP under 65 mmHg by the time interval between the first and the last MAP measurements.

    MAP measurements are recorded every minute from of anesthesia induction to end of wound closure.

Secondary Outcomes (11)

  • AUC-MAP under 65 mmHg.

    From of anesthesia induction to end of wound closure.

  • Duration of MAP under 65 mmHg.

    From of anesthesia induction to end of wound closure.

  • Time-weighted average (TWA) intraoperative mean arterial pressure (MAP) under 70 mmHg.

    From of anesthesia induction to end of wound closure.

  • AUC-MAP under 70 mmHg.

    From of anesthesia induction to end of wound closure.

  • Duration of MAP under 70 mmHg.

    From of anesthesia induction to end of wound closure.

  • +6 more secondary outcomes
