Summary

Dexmedetomidine can prolong the duration of local anesthetics, but the effect of perineural dexmedetomidine on the potency of ropivacaine for brachial plexus blocks in pediatric patients has not been investigated. This study was designed to determine the effect of perineural dexmedetomidine on ropivacaine for brachial plexus blocks in pediatric patients

Interventions

DRUG

perineural dexmedetomidine

Children scheduled for arm and forearm surgery underwent supraclavicle brachial plexus blocks with ropivacaine and dexmedetomidine guided by ultrasound visualisation were randomly assigned five groups: Group A (perineural ropivacaine), Group B (ropivacaine plus 0.5 mcg/kg dexmedetomidine), Group C (ropivacaine plus 1 mcg/kg dexmedetomidine), Group D (ropivacaine plus 1.5mcg/kg dexmedetomidine) and Group E (ropivacaine plus 2 mcg/kg dexmedetomidine). In each group, children received a certain concentration of ropivacaine which adjusted by the "Dixon up-and-down method for supraclavicle brachial plexus. The first child received 0.2% ropivacaine , and the concentration of ropivacaine varied by 0.1% according to the up-and-down method. The primary endpoint was the minimum local anesthetic concentration (MLAC).
