NCT07377695

Brief Summary

The purpose of this prospective randomized controlled trial is to compare the total consumption of remimazolam between two different administration methods-Target-Controlled Infusion (TCI) and manual infusion-in patients undergoing cerebrovascular bypass surgery.

Outcome Measures

Primary Outcomes (1)

  • Total Consumption of Remimazolam

    The total cumulative dose of remimazolam ($mg$) administered from the initiation of anesthesia induction until the completion of the surgical procedure.

    From the start of anesthesia induction to the end of surgery (intraoperative period).

Study Arms (2)

TCI

EXPERIMENTAL

Remimazolam administered via TCI (target Ce 0.7 μg/mL)

Other: Target-Controlled Infusion (TCI) of Remimazolam

Manual Infusion

ACTIVE COMPARATOR

Remimazolam administered via manual infusion (6 mg/kg/hr for induction, 1-2 mg/kg/hr for maintenance)

Other: Manual Infusion of Remimazolam

Interventions

Remimazolam is administered using a target-controlled infusion (TCI) pump based on the Schuttler pharmacokinetic model. The initial target effect-site concentration (Ce) is set at 0.7 μg/mL and adjusted in 0.1 μg/mL increments to maintain a depth of anesthesia between Patient State Index (PSi) 25 and 50.

TCI

Remimazolam is administered via traditional manual weight-based infusion. For anesthesia induction, a rate of 6 mg/kg/hr is used. For maintenance, the infusion rate starts at 1 mg/kg/hr and is adjusted in 0.2 mg/kg/hr increments to maintain a PSi between 25 and 50.

Manual Infusion
