Research progress on ultrasound-guided costo-clavicular brachial plexus block
Brachial plexus block is one of a common anesthesia technique for upper limb surgery. Compared to general anesthesia,brachial plexus anesthesia can reduce the impact of anesthetic drugs on various systems and is simple and effective to administers. The commonly used approaches for brachial plexus block include the interscalene,supraclavicular,infraclavicular,and axillary approaches. With the rapid development of anesthesia and ultrasound technology,a new approach called the costo-clavicular brachial plexus block has emerged. Compared to traditional methods,the lateral,medial,and posterior cords of the brachial plexus in the costo-clavicular space are more superficial and located outside the axillary artery. Therefore,ultrasound-guided costo-clavicular brachial plexus block requires less time for needle insertion,has a faster onset,requires a lower dosage of local anesthetics,and has fewer complications,making it widely recognized in clinical practice.
