Patient-controlled Remimazolam Sedation Under Spinal Anesthesia
16 de junio de 2026 actualizado por: Seokha Yoo, Seoul National University Hospital
Patient-controlled Remimazolam Sedation During Primary Hip Arthroplasty Under Spinal Anesthesia: an Open-Label Randomized Controlled Trial
The goal of this clinical trial is to compare the efficacy of patient-controlled sedation (PCS) versus clinician-controlled sedation (CCS) using remimazolam in adult patients undergoing primary hip arthroplasty under spinal anesthesia.
The main questions it aims to answer are:
- Does patient-controlled sedation significantly reduce the total consumption of remimazolam compared to clinician-controlled sedation?
- Are there differences in secondary outcomes, such as sedation depth , sedation-related adverse events, frequency of airway interventions, and patient/surgeon satisfaction?
Researchers will compare the PCS group to the CCS group to see if the patient-controlled method leads to a reduction in total remimazolam consumption while maintaining effective sedation.
Participants will:
- Be randomly assigned to either the PCS group or the CCS group.
- In the PCS group: Receive an initial 0.05 mg/kg remimazolam dose over 1 minute. If deeper sedation is desired, the patient can self-administer a 1 mg bolus of remimazolam via a button press, which has a 1-minute lockout interval.
- In the CCS group: Receive an initial 0.05 mg/kg remimazolam dose over 1 minute, followed by a continuous infusion starting at 0.3 mg/kg/h. The clinician will assess the MOAA/S score every 10 minutes and adjust the infusion rate to maintain a target MOAA/S score of 3.
