Abstract: Objective To analyze electrophysiology of peripheral nerve in uremic patients. Methods 24 uremic patients and 19 normalvolunteers were included, surface electrodes were used to observe the electrophysiology performance, including tibial nerve, peroneal nerve,sural nerve and skin sympathetic response. Results The motor conduction, sensory conduction and skin sympathetic response were significantlydifferent between uremia patients and normal volunteers (P<0.05). The electrophysiology performance showed that F wave latencyprolonged, nerve conduction slowed, distal latencies prolonged, sensory fibers damaged more serious than motor fibers. Conclusion Peripheralneuropathy is one of the most common complications in uremia patients, neural electrophysiological abnormalities are significantly earlierthan clinical symptoms, nerve electrophysiological examination is of great significance in diagnosis and evaluation uremic peripheralneuropathy.
