糖尿病性周围神经病患者受累神经的分布特点

Distribution characteriatics of involved nerves in patients with diabetic peripheral neuropathy

目的探讨糖尿病性周围神经病(DPN)患者受累神经的分布特点。方法对900例2型糖尿病并发DPN患者进行感觉及运动神经传导速度检测,对受累神经的分布进行分析。结果本组感觉神经异常率为89.3%;包括65.2%(587例)的正中神经、38.9%(350例)的尺神经、89.3%(804例)的腓浅神经、60.4%(544例)的腓肠神经及29.6%(64例)的胫后神经异常。运动神经异常率为34.5%;包括32.1%(289例)的正中神经、28.7%(258例)的腓总神经、22.7%(49例)的胫神经异常。感觉神经异常率明显高于运动神经异常率(P<0.01);下肢感觉神经异常率明显高于上肢(P<0.01)。结论 DPN患者受累的感觉神经以腓浅神经、正中神经、腓肠神经最普遍,受累的运动神经以正中神经、腓总神经为多见。

Objective To observe the distribution characteristics of involved nerves in patients with diabetic peripheral neuropathy（DPN）. Methods The sensory and motor nerve conduction velocity were defected in 900 type 2 diabetes patients complicated DPN. Results In this group, the abnormal rate of sensory nerve was 89.3%, including 65.2% （587 cases） median nerves, 38.9% （350 cases） ulnar nerves, 89.3% （804 cases） superficial peroneal nerves, 60.4% （544 cases）sural nerves and 29.6% （64 cases）posterior tiabial nerves. The abnormal rate of motor nerve was 34.5% , including 32. 1% （289 cases） median nerves, 28.7% （258 cases） common peroneal nerves and 22.7% （49 cases） in tiabial nerves. The abnormal rate of sensory nerve was significantly higher than motor nerves（ P 〈 0. 01 ） ; and which in lower limbs was significantly higher than upper limbs （ P 〈 0. 01 ）. Conclusion In DPN patients, sensory nerves such as superficial peroneal nerve, median nerve and sural nerve, and motor nerves such as peroneal nerve and median nerve are the most common involved nerves.
