Abstract:
Objective:To measure the parameters of median nerve under ultrasound in patients with diabetes mellitus to explore the relationship between ultrasonic parameters and nerve conduction study. Methods:From June to November, 2019, 79 diabetic patients were divided into diabetic peripheral neuropathy (DPN) group (n = 37) and non-DPN group (n = 42) according to the diagnosis. Their right median nerve were measured cross-sectional area (CSA) and the proportion of hypoechoic areas (HA) 5 cm and 10 cm proximal to the wrist (CSA-5, CSA-10, HA-5 and HA-10, respectively) with sonography; while the conductive latency and velocity of right median nerves were measured with nerve conductive study. Results:CSA-5, CSA-10 and HA-10 were more in DPN group than in non-DPN group (|Z| > 2.282, P < 0.05). HA-5 correlated with the motor conductive latency (r = 0.264, P < 0.05) and velocity (r = -0.270, P < 0.05); HA-10 correlated with the abnormal sensory conductive latency (r = 0.234, P < 0.05) and velocity (r = 0.363, P < 0.01), and the motor conductive latency (r = 0.235, P < 0.05) and velocity (r = -0.255, P < 0.05). Conclusion:DPN can be found under sonography, some of them are related with the nerve electrophysiology, which may be a useful tool to screen DPN.
