Objective:To evaluate the effectiveness and side effects, complications of interscalene brachial plexus block with a nerve stimulator for clavicular fracture surgery. Materials and Methods:In a prospective descriptive study, fifty patients received interscalene brachial plexus block for fixation of clavicle fracture. The dose was 7 mg/kg of 1% lidocaine mixed with 1 : 200000 adrenaline. Results:The success rate was 94%, including 4% of patients needed sedation and small amount of narcotic, failure rate was 6%. The minimal stimulating current of the nerve location was 0.46 ±0.08 mA, the onset time of sensory block was 8.86 ±2.65min. There were 3 complications with one Horner’s syndrome and two hoarsenesses. Conclusion:We found that in patients undergoing fixation of clavicle fracture the interscalene block with a nerve stimulator was an effective anesthetic with a low rate of side effects and complications.
Key words:Interscalene block, nerve stimulator, clavicular fracture surgery.
