Not applicable Interventional Samsung Medical Center · NCT06115031

This study is testing if using remimazolam instead of propofol during neurosurgery can help reduce the chances of patients experiencing delirium after their operation.

What this trial studies

This study evaluates the incidence of postoperative delirium in neurosurgical patients receiving either remimazolam-based or propofol-based total intravenous anesthesia (TIVA). Remimazolam is a newly approved short-acting benzodiazepine that may offer a safer alternative to propofol, which has been associated with higher rates of postoperative complications. The trial is designed as a prospective, randomized, double-blinded, active comparator-controlled, non-inferiority trial to assess the effectiveness and safety of remimazolam compared to propofol. The study aims to provide insights into the potential benefits of remimazolam in reducing postoperative delirium.

Who should consider this trial

Good fit: Ideal candidates for this study are patients classified as ASA class I to III who are undergoing neurosurgery.

Not a fit: Patients with severe respiratory, cardiovascular, or hepatic disease, or those with preoperative delirium, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved anesthesia protocols that reduce the incidence of postoperative delirium in neurosurgical patients.

How similar studies have performed: While there is limited research specifically comparing remimazolam to propofol regarding postoperative delirium, the safety profile of remimazolam suggests potential for success in this novel approach.
