Evaluation of dexmedetomidine as an adjuvant to low-concentration lidocaine/ropivacaine mixtures in ultrasound-guided axillary brachial plexus block.

ABSTRACT:

Background

Dexmedetomidine (DEX) can be used with local anesthetics (LAs) to enhance the efficiency of a peripheral nerve block. However, there have been few studies on the combination of DEX and two different LAs for a brachial plexus block (BPB). The effects of adding DEX to low concentrations of lidocaine (LIDO) mixed with ropivacaine (ROP) on block onset, duration of anesthesia, and efficacy of analgesia in ultrasound-guided axillary (UGA) BPB were investigated.

Methods

The study protocol was approved by the Ethics Committee of the Second Affiliated Hospital of Harbin Medical University (ChiCTR-IPR-16007742, January 12, 2016), China. Seventy-five patients designated as American Society of Anesthesiologists Physical Status Classification System I or II and scheduled for f
