A sequential allocation study to determine the ED of Dexmedetomidine as an adjuvant to lidocaine intravenous regional anesthesia.

Clonidine is effective in overcoming this shortcoming when used with intravenous regional anesthesia at a dose of 1 μg/kg. Dexmedetomidine has also been used successfully at a dose of 0.
