Title: Application effect of B ultrasound-guided low concentration of ropivacaine in brachial plexus block in pediatric upper extremity surgery
Abstract: Objective To explore the feasibility of the application of B ultrasound-guided low concentrations of ropivacaine in brachial plexus block in pediatric upper extremity surgery. Methods 40 cases of pediatric patients who will electively accepted upper limb operation were randomly divided into two groups(n=20).In the group A,the clinical commonly used concentration of ropivacaine was selected,0.33% ropivacaine+0.7% lidocaine,the brachial plexus block was given blindly;while in the group B,low concentration of ropivacaine was adopted,0.1% ropivacaine+0.7% lidocaine,then the B ultrasound-guided brachial plexus block was given.The anesthesia analgesic onset time,duration of anesthesia and analgesia,motion recovery time and brachial plexus block failure rate in the two groups of children were compared. Results Both the onset time of analgesia and motion recovery time of group B were shorter than that of group A(P0.05); while the brachial plexus block failure rate of group A was significantly higher than that of group B(P0.05);there were no significant differences in the anesthesia analgesic duration of the two groups(P 0.05). Conclusion The B ultrasound-guided low concentration of ropivacaine in brachial plexus block can be safely applied in pediatric upper extremity surgery.
