简要总结
The primary aim of this study is to compare needle shaft visibility between the retroclavicular approach and costoclavicular approach for infraclavicular brachial plexus block in patients undergoing elective upper limb surgery. Secondary aim is to investigate the differences between the two groups in sensorial block success rate, block performance time, block performance related pain, motor block success rate, surgical success rate, complications, patient satisfaction, use of supplemental local anesthetic, use of analgesic.
详细描述
Infraclavicular blocks are performed with different approaches. This study evaluated the effectiveness, safety and feasibility of a retroclavicular brachial plexus block as compared with costoclavicular approach for infraclavicular brachial plexus block. 60 patients scheduled for elective upper limb surgery were recruited and randomized into two groups: Retroclavicular approach for infraclavicular block (Group I), costoclavicular approach for infraclavicular block (Group R). Sensory block, adverse effects and complications were evaluated and recorded every 5 minutes until 30 min after local anesthetic injection. Success rate of each nerve sensory block, complications, rate of satisfaction, rate of failure and incidence rate of adverse effects, the needle shaft visibility, procedure time,duration of the block's effect, use of supplemental local anesthetic, use of analgesic are compared with both groups.
