Outcome Measures
Primary Outcomes (1)
Percent of Patients With Monitorable of Motor Evoked Potentials
Monitorable is defined as stable signals being present in 3 muscles in each lower extremity, with mean peak-to-peak amplitude of at least 50 uV, and with mean-normalized interquartile variability of 0.9 or less.
During a single surgery for the duration of the operation
Study Arms (2)
High dose dexmedetomidine
EXPERIMENTALPatients will receive dexmedetomidine 0.5 mcg/kg/hr plus propofol 50 mcg/kg/min
Low dose dexmedetomidine
ACTIVE COMPARATORPatients will receive dexmedetomidine 1.0 mcg/kg/hr plus propofol 25 mcg/kg/min
Interventions
Patients will randomly assigned to received Arm 1 anesthesia or Arm 2 anesthesia during surgery.
Eligibility Criteria
You may qualify if:
- Patients undergoing multi-level posterior spine fusions requiring motor evoked potential monitoring
You may not qualify if:
- Allergy to dexmedetomidine, propofol
- Conditions knows to make recording of motor evoked potentials difficult, including poorly controlled diabetes, severe peripheral neuropathy, severe myelopathy, or previous surgery during which motor evoked potentials were difficult to obtain
- Hepatic disease
