简要总结
This trial was conducted to compare the ease of performance and effectiveness of ultrasound guided supraclavicular, infraclavicular and interscalene techniques of bracheal plexus block for upper arm and forearm surgery. Sixty adult patients of ASA grade I-III undergoing upper limb surgery were randomly allocated into 3 groups to receive ultrasound-guided supraclavicular, infraclavicular and interscalene blocks.The imaging times and block performance times were comparable among groups. Though, the onset time was longer in interscalene group as compared to other groups, no difference was observed in the success rate, duration of analgesia and adverse effects. We concluded that ultrasound guided interscalene block can be performed as rapidly as supraclavicular and infraclavicular blocks and results in similar success rate for upper limb surgery.
