Delirium Clinical Trial
Official title:
Effect of Dexmedetomidine-Esketamine Combination for Sedation and Analgesia on Delirium in ICU Patients With Mechanical Ventilation: A Multicenter Randomized Trial
Patients with mechanical ventilation in the intensive care unit (ICU) often develop anxiety and agitation, sleep distuebances, and delirium. Delirium occurrence is associated with worse early and long-term outcomes. Dexmedetomidine and ketamine are recommended for sedation and analgesia in ICU patients, but each may induce side effects. The sedative effects of dexmedetomidine can help mitigate the psychiatric side effects of esketamine. Recent studies showed that dexmedetomidine-esketamine combination improved analgesia and sleep quality without increasing psychiatric side effects. This trial is designed to test the hypothesis that dexmedetomidine-esketamine combination for sedation and analgesia in ICU patients with mechanical ventilation may reduce delirium and improve respiratory recovery.

Secondary | Days alive without delirium or come during the 14-day period | Delirium is assessed twice daily with the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) or the 3-Minute Diagnostic Assessment for Delirium using the Confusion Assessment Method (3D-CAM). Coma is defined as Richmond Agitation Sedation Scale (score ranges from -5 [unarousable] to +4 [combative] and 0 indicates alert and calms) of -4 or -5. Positive results at any timepoint is defined as occurrence of delirium or coma. | Up to 14 days after enrollment | |
