Arms Assigned Interventions
Active Comparator: Dexmedetomidine
Patients in this arm will receive continuous dexmedetomidine infusion (0.2 - 1.5 mcg/kg/hour) titrated to the target Richmond Agitation Sedation Scale for the duration of mechanical ventilation or 7 days on study, whichever is first.
Drug: Dexmedetomidine
continuous IV infusion 0.2 - 1.5 ucg/kg/hour titrated to target RASS
Other Name: Precedex
Drug: Fentanyl
25 - 200 mcg IV every hour (as multiple IV pushes) as needed titrated to Non-Verbal Pain Scale
Drug: Midazolam
0.01 - 0.1 mg/kg IV push every 10 minutes as needed for agitation (RASS>+2)
Other Name: Versed
Behavioral: Physical and Occupational Therapy
Daily therapy sessions targeting range of motion, strength, and mobility
Active Comparator: Propofol
Patients in this arm will receive propofol (5 - 50 mcg/kg/min) for sedation, titrated to the target Richmond Agitation Sedation Scale for the duration of mechanical ventilation or 7 days on study, whichever is first.
Drug: Propofol
continuous IV infusion (5 - 50 ucg/kg/min) titrated to target RASS
Other Name: Diprivan
Drug: Fentanyl
25 - 200 mcg IV every hour (as multiple IV pushes) as needed titrated to Non-Verbal Pain Scale

Other Name: Versed
Behavioral: Physical and Occupational Therapy
Daily therapy sessions targeting range of motion, strength, and mobility

Detailed Description:

Mechanically ventilated critically ill patients are routinely given sedative and analgesic medications to relieve pain and anxiety associated with intubation, mechanical ventilation, and critical care in general. While integral in minimizing discomfort, these medications may increase mechanical ventilation time, the duration of intensive care unit (ICU) stay, ICU complications (e.g. delirium, ventilator associated pneumonia, venous thromboembolism), the morbidity associated with critical illness, and patient mortality. This study compares two sedative medications that have been used in patients who require a mechanical ventilator. Enrolled patients will be randomly assigned to receive propofol or dexmedetomidine for sedation while they require ventilatory support. All patients will also receive the pain medication fentanyl as needed.
