A Pilot Study of Dexmedetomidine-Propofol in Children Undergoing Magnetic Resonance Imaging

Summary

This is a pilot study to determine if a standard bolus dose and infusion of dexmedetomidine can significantly decrease the dose of propofol (infusion) required for accomplishing an MRI. The investigators studied three arms to examine the effectiveness of dexmedetomidine. Arm 1 was a single bolus of 1.0 mcg/kg with 1.0 mcg/kg/hr infusion followed by propofol infusion. Arm 2 was a bolus of 1.0 mcg/kg with 0.5 mcg/kg/hr infusion followed by propofol infusion. Arm 3 was only a single bolus of 1.0 mcg/kg with no infusion followed by propofol infusion.
