A Randomized, Double-blind Trial in Ventilated ICU Patients Comparing Treatment With an Alpha2 Agonist Versus a Gamma Aminobutyric Acid (GABA)-Agonist to Determine Delirium Rates, Efficacy of Sedation, Analgesia and Discharge Cognitive Status
In Brief
A Phase 2 clinical trial evaluating Dexmedetomidine and Lorazepam for Delirium. Completed, enrolled 100 participants across 1 site.
Detailed Summary
Delirium has recently been shown as a predictor of death, increased cost, and longer length of stay in ventilated patients. Sedative and analgesic medications relieve anxiety and pain, but may contribute to patients' transitioning into delirium. It is possible that modifying the paradigm for sedation using novel therapies targeted at different receptors, such as dexmedetomidine targeting alpha2 receptors and sparing the GABA receptors, could provide efficacious sedation yet reduce the development, duration, and severity of acute brain dysfunction (delirium).

Timeline
Interventions
a bolus dose of 1 μg/kg infused over 10 minutes followed by an infusion started at 0.15- 0.45 μg/kg/hr. Dexmedetomidine will be titrated every 10 minutes to achieve set target RASS score. The maximum dexmedetomidine infusion will be 1.5 μg/kg/hr.
Patients in the lorazepam arm will receive a bolus dose of 1-3 mg followed by an infusion started at 1-3 mg/hr. Lorazepam infusion will be titrated every 10 minutes to achieve set target RASS score. The maximum lorazepam infusion will be 10 mg /hr.
