Abstract:
Objective To compare the efficacy of different volume of ropivacaine and lidocaine for ultrasound-guided infraclavicular brachial block.Methods Sixty patients scheduled for distal upper limb surgery were divided into group A and group B by random digits table method with 30 cases each.The patients were given ultrasound-guided infraclavicular brachial block,but the patients in group A using 0.3％ ropivacaine mixed with 1％ lidocaine 20 ml,the patients in group B using the same mixture 30 ml.Sensory block was assessed every 5 min after the block.Motor block was evaluated at 30 min after the block.The onset time of anesthesia,surgical success rate,complications and duration of anesthesia were recorded.Results There was no significant difference in the surgical success rate [93.3％(28/30) vs.96.7％(29/30),P＞0.05],onset time of sensory block [10 (5) min vs.5 (5) min,P＞0.05] and degree of motor block between the 2 groups.The duration of anesthesia in group A was shorter than that in group B (P ＜ 0.05).Conclusion The efficacy of ultrasound-guided infraclavicular brachial block with the mixture of 0.3％ ropivacaine and 1％ lidocaine 20 ml and 30 ml is similar in surgical success rate and onset time of anesthesia.
