Perineural Dexmedetomidine and Femoral Nerve Block

• Status: Unknown status
• Trial end date: 2014-01-01
• Target enrollment: 0
• Participant gender: All

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.

• Phase: Phase 4
