Low-dose Dexmedetomidine for Delirium Prevention in Mechanically Ventilated Patients in Intensive Care Unit: a Multicenter, Randomised, Double-blinded, Placebo-controlled Trial
In Brief
A Phase 4 clinical trial evaluating Dexmedetomidine and Placebo (normal saline) for Adult Disease and 4 related conditions. Suspended, targeting 260 participants across 1 site.

Detailed Summary
For patients undergoing mechanical ventilation, light sedation is better than deep sedation for the outcomes, which is manifested as shortened length of ICU stay, shortened duration of mechanical ventilation, and decreased mortality. In a recent study of the investigators, low-dose dexmedetomidine without sedative effects (0.1 ug/kg/h) improved sleep quality and reduced the incidence of delirium in elderly patients admitted to the ICU after surgery. The investigators hypothesize that, for ICU patients with prolonged mechanical ventilation, low-dose dexmedetomidine infusion (0.1 ug/kg/h) may also be effective in decreasing delirium. The purpose of this study is to investigate whether low-dose dexmedetomidine infusion can reduce the incidence of delirium in ICU patients with prolonged duration of mechanical ventilation (\>= 24 hours).

Interventions
Dexmedetomidine is administered as a continuous intravenous infusion at a rate of 0.025 mL/kg per h (0.1 μg/kg per h) from study recruitment in the ICU for no more than 72 hours.
Placebo (normal saline) is administered as a continuous intravenous infusion at a rate of 0.025 mL/kg per h from study recruitment in the ICU for no more than 72 hours.
