Abstract
Objective To evaluate the efficacy and safety of dexmedetomidine added to ropivacaine for interscalene brachial plexus blockade. Methods Sixty eight patients scheduled for elective forearm and hand surgery were randomly as-signed to receive 25ml(125mg) of 0.5%ropivacaine+1μg/kg dexmedetomidine(group D, n=34) or 25ml(125mg) of 0.5%ropiva-caine (group C, n=34) for interscalene brachial plexus block. The nerves in the interscalene were identified using neural stimulator. The onset times of motor and sensory block, block duration, and adverse events after local anesthesia were documented. Results The onset times of sensory and motor block were shorter in group D than those in group C (P<0.05). The durations of sensory and motor blockade were longer in group D than those in group C (P<0.05). The incidence of bradycardia was significantly higher in group D than that in group C(P<0.05). Conclusion Dexmedetomidine added to ropivacaine for interscalene brachial plexus block guided by neural stimulator shortens the onset time and prolongs the duration of the block;however, it may lead to bradycardia.关键词
