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).

Conditions

  • Delirium

Interventions

DRUG

Dexmedetomidine

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.

DRUG

Lorazepam

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.
