Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Dexmedetomidine
Other interventions - Placebo

Experimental: Dexmedetomidine Intervention - Patients randomized to the experimental arm will receive dexmedetomidine. At initiation, a bolus will NOT be administered. In keeping with Health Canada. Guidelines, the infusion will start at a mid-range dose of 0.6mcg/kg/h with titration either up or down by 0.1mcg/kg/h every 20-30 minutes to a maximum rate of 1.2mcg/kg/h to maintain light sedation (Richmond Agitation-Sedation Scale \[RASS\] = -2 to +1 or Riker Sedation-Agitation Scale \[SAS\] 3-4).

Placebo comparator: Control Intervention - Those in the control group will receive a placebo that is identical in colour and packaging and at equal volume to the intervention group. Each bag of placebo contains 50mL of 0.9% sodium chloride and labeled as per Health Canada guidance for labelling pharmaceutical drugs for use in humans.


Treatment: Drugs: Dexmedetomidine
Dexmedetomidine is an a2-adrenergic agonist sedative commonly used in invasive mechanical ventilation that promotes patient wakefulness, has no effect on respiratory drive, has important analgesic properties, and when compared to ?-aminobutyric acid receptor agonists like benzodiazepines, reduces delirium.

Other interventions: Placebo
Normal saline placebo will be given as continuous infusion.
