Abstract:
Objective To evaluate the efficacy of ultrasound-guided combined C5 and superficial cervical plexus block in patients undergoing clavicle surgery.Methods Sixty ASA physical status Ⅰ or Ⅱ patients,scheduled for elective clavicle surgery,were randomly divided into 2 groups (n =30 each) using a random number table:injection with 10 ml local anesthetic guided by ultrasound group (group U),and injection with 10 ml local anesthetic guided by anatomical landmark group (group A).A mixture of 0.375 ％ levobupivacaine and 1.0％ lidocaine was used.The time spent performing the block onset time of analgesia,onset time of analgesia in the medial border,midpoint and lateral border of the clavicle and duration of analgesia were measured.The effectiveness of block (excellent,good,failure) was assessed.The complications were observed.Results Compared with group A,the time spent performing the block was significantly prolonged,the onset time of analgesia in the lateral border and midpoint of the clavicle was shortened,the rate of excellent anesthesia was increased,and the duration of analgesia was prolonged in group U (P ＜ 0.05).No complications occurred in group U,while vascular puncture occurred in 3 cases,and one patient developed mild toxic reaction in group A.Conclusion Ultrasound-guided combined C5 and superficial cervical plexus block provides better block,with faster onset time of analgesia in the lateral border and midpoint of the clavicle,longer duration of analgesia and fewer complications as compared with that guided by anatomical landmarks in patients undergoing clavicle surgery.
