If the patient's birth year ends in an odd number, the order set will open the trial arm. Here, the ICU resident will be able to order midazolam and fentanyl in a sliding scale fashion. Doses will be started at the same doses as the infusion medications; for midazolam 1 mg/hr, for fentanyl 25 mcg/hr and titrated to target RASS -1 or CPOT = 0. Dosing may be modified for creatinine clearance, hemodynamics, and opiate naivety.
