Assessing the safety and effectiveness of remazolam besylate for sedation in critically ill patients on ventilators after surgery

Efficacy and Safety of Remazolam Besylate in Patients Requiring Mechanical Ventilation Admitted to ICU After Non-cardiac Surgery: Protocol for a Randomized, Controlled No-inferiority Trial

Phase 4 Interventional Beijing Shijitan Hospital, Capital Medical University · NCT06575530

This study is testing if a new sedative called remazolam besylate is safe and effective for helping critically ill patients on ventilators after surgery, compared to a standard sedative.

What this trial studies

This clinical trial is a multi-center, prospective, randomized, double-blind, no-inferiority study aimed at evaluating the safety and efficacy of remazolam besylate compared to dexmedetomidine for sedation in critically ill patients who are mechanically ventilated following elective surgery. Participants will be adults aged 18-64 who require light to moderate sedation and have been admitted to the ICU with tracheal intubation. The study will focus on measuring the effectiveness of sedation and monitoring for any adverse drug events during the mechanical ventilation period.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-64 who are undergoing non-cardiac elective surgery and require mechanical ventilation post-operatively.

Not a fit: Patients with severe neurological conditions, significant cardiac dysfunction, or those who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer and more effective sedation option for critically ill patients requiring mechanical ventilation after surgery.

How similar studies have performed: While there have been studies on sedation in critically ill patients, the specific use of remazolam besylate in this context is relatively novel and has not been extensively tested.
