神经传导速度检测对2型糖尿病周围神经病变的早期诊断价值探讨

The value of nerve conduction velocity detection in early diagnosis of peripheral neuropathy in type 2 diabetes

目的：探讨神经传导速度检测对2型糖尿病周围神经病变的早期诊断价值。方法对2014年5月至2015年5月就诊的首次确诊为2型糖尿病的94例患者进行运动神经传导速度（MCV）和感觉神经传导速度（SCV）检测，统计神经传导速度检测结果，并对比分析神经传导速度检测对糖尿病周围神经病（DPN）的诊断率和临床诊断率。结果所检测患者中，下肢神经传导速度异常率较高，尤其是腓浅神经 SCV 异常率最高（69．1％）。神经传导速度检测对 DPN 的诊断率为71．3％，临床诊断率为33．0％，两者比较，差异有统计学意义（χ2＝8．195，P ＝0．004）。结论神经传导速度检测对 DPN 的早期诊断具有重要价值，对于初次确诊为2型糖尿病的患者，应对其进行神经传导速度检测，可提高早期 DPN 的检出率。

Objective To investigate the value of nerve conduction velocity detection in early diagnosis of peripheral neuropathy in type 2 diabetes.Methods Motor nerve conduction velocity （MCV）and sensory nerve con-duction velocity （SCV）for 94 patients were detected who was the first time diagnosed type 2 diabetes in our hospital from May 2014 to May 2015.The statistic results of nerve conduction velocity were conducted and then compared with clinical diagnosis to analyze the diagnosis rate for diabetic peripheral neuropathy （DPN）.Results The abnormal rate of lower limb nerve conduction velocity was higher in the examined patients,which in the SCV of superficial peroneal nerve was especially highest（69.1%）.The diagnostic rate of nerve conduction velocity in DPN was 71.3%,and the clinical diagnosis rate was 33.0%.The difference was statistically significant between the two diagnostic methods （χ2 =8.195,P =0.004）.Conclusion Nerve conduction velocity detection has important value for the early diagno-sis of DPN.Patients for the first time diagnosed with type 2 diabetes should be carried out this detection to improve the diagnosis rate of DPN.
