Summary

The REPAIR Trial is a single-center, prospective, randomized, parallel-group superiority trial enrolling 320 adults scheduled for elective cytoreductive surgery (CRS) with or without hyperthermic intraperitoneal chemotherapy (HIPEC). Participants will be assigned 1:1 to bispectral index-guided remimazolam- or propofol-based general anesthesia under standardized perioperative care. The primary objective is to determine whether remimazolam improves patient-reported recovery 48 ± 4 hours after surgery, measured by the Chinese 15-item Quality of Recovery score (QoR-15; range, 0 to 150; higher scores indicate better recovery). The investigators hypothesize that remimazolam will produce a higher 48-hour QoR-15 score than propofol. Secondary outcomes will characterize recovery at 24 and 72 hours, intraoperative hypotension burden and vasopressor use, acute kidney injury, infection, delirium, respiratory complications, other safety events, and 30-day mortality.

Interventions

DRUG

Remimazolam

Remimazolam is infused intravenously at 6 mg/kg/hour for induction. If a Modified Observer's Assessment of Alertness/Sedation score of 1 or lower is not reached after 3 minutes, the rate is increased to 12 mg/kg/hour. After loss of consciousness, maintenance starts at 1.0 mg/kg/hour and is adjusted in steps of 0.2 mg/kg/hour at intervals of at least 5 minutes within an allowed range of 0.5 to 2.0 mg/kg/hour to maintain BIS 40 to 60. Infusion stops at completion of skin closure. Dosing weight is actual body weight for BMI below 30 kg/m² and adjusted body weight for BMI of 30 kg/m² or higher. Flumazenil is not used routinely and is reserved for clinically indicated rescue.

DRUG

Propofol

Propofol 1.5 to 2.5 mg/kg is administered intravenously over 60 to 90 seconds for induction. After loss of consciousness, maintenance starts at 6 mg/kg/hour and is adjusted in steps of 1 mg/kg/hour at intervals of at least 5 minutes. The usual range is 4 to 10 mg/kg/hour and the allowed range is 3 to 12 mg/kg/hour to maintain BIS 40 to 60. Infusion stops at completion of skin closure. Dosing weight is actual body weight for BMI below 30 kg/m² and adjusted body weight for BMI of 30 kg/m² or higher.
