Looking for Minimum Dose to Induce Sympathectomy in Infraclavicular Brachial Plexus Block

Summary

For patients who undergoing hemodialysis, it is important to have good AV fistula. One third of AV fistula usually fail during early stage. It is helpful to use nerve block to dilate the blood vessels and enhance the prognosis. But 0.2% Ropivacaine usually cause muscle weakness in present studies. The investigators hope to find the lowest concentration to provide sympathectomy without muscle weakness. Because the patients with hemodialysis usually have multiple co-morbidity, thus we choose patients with forearm fracture at the first place. With this result, the investigators can design further study for patients with hemodialysis. The investigators prefer proximal approach because brachial plexus run together in the cosctoclavicular space and show lower incidence of incomplete work.
