Abstract:
Objective To investigate the efficacy and safety to children of different concentration ropivacaine used for braehial plexus block in upper-limb paediatfic surgery.Methods After undergoing basal anesthesia with ketamine,100 children scheduled for hand and forearm surgery were randomly allocated to receive brachial olexus block.Brachial plexus block was performed separately with 0.33% ,0.25% ,0.2% ,0.167% ropivacaine in four group.The onset time and complete time of sensory blockade of ulner nerve,medial nerve and radial nerve;duration of analgesia;satisfaction degree of nerve block and complications were recorded.Results MAP and HR in group D was higher than before anesthesia at T1,T2,T3,and was higher compared with other three groups at T1,T2 ,T3.There wasn' t significantly difference in anesthetic effect among A,B,C group and D group was the worst,compared with other three groups.The amount of ketamine and the rate of adverse reactions in D group was significantly more than that in other three groups.The time of analgesic and movement to restore was shorter than that in other three groups.Conclusion 0.25% ropivacaine was more applicable to children with anesthetized perfectly and less complication.
