As a late stage of renal failure, uremia not only leads to severe impairment of renal function in patients, but also often leads to a variety of complications, among which multiple peripheral neuropathy is particularly common. This lesion is mainly caused by the combination of multiple mechanisms, such as the accumulation of uremic toxins, electrolyte disorder, nutrient deficiency and factors related to hemodialysis. Therefore, it is important clinical significance to deeply explore the effects of uremia on electrophysiological properties and nerve block of brachial plexus. At present, there are relatively few studies on the effects of uremia on the brachial plexus, especially the prospective parallel cohort studies on its electrophysiological properties and nerve block. As a new anesthetic technique, ultrasound-guided axillary brachial plexus block has the advantages of precise positioning, scientific administration, reducing complications and improved safety, but the application effect and safety in uremic patients still need to be further verified.
