Summary
The duration of sensory block after single dose of long acting local anesthetics is not
sufficient to avoid the postoperative use of opioids. Alpha-2 adrenoceptor agonists such as
clonidine have been shown to increase the duration of peripheral nerve block. Dexmedetomidine
is a more potent and selective α-2-adrenoceptor compared to clonidine. To the best of our
knowledge, the use of Dexmedetomidine as adjuvant to local anesthetic was not previously
reported for femoral nerve block.
