神经传导速度测定对糖尿病合并肘管综合征的诊断意义

Measurement of nerve conduction velocity in patients with diabetes mellitus and its significance in the diagnosis of cubital tunel syndrome

目的对糖尿病并发肘管综合征患者的神经传导速度测定结果进行分析。方法对85例糖尿病患者行神经传导速度及肌电图检测,统计糖尿病周围神经损害及肘管综合征的比率。结果 85例患者中周围神经损害36例,符合肘管综合征诊断11例(12.9%),其中糖尿病周围神经损害合并肘管综合征7例,单纯肘管综合征4例,双侧均有损害的3例。肘管综合征表现为肘下-肘上运动神经传导速度减慢(同上臂比较>10m/s),并有腕—小指感觉神经电位波幅降低8例,肘下-肘上运动电位波幅降低(>50%)伴小指展肌、第一骨间肌出现自发电位3例。结论糖尿病患者中并发肘管综合征的患者并不少见,可能存在卡压机制,并且神经传导速度测定可以及早发现糖尿病并发的肘管综合征,使患者能及时得到治疗。

Objective To analyze the nerve conduction velocities in diabetes mellitus patients with cubital tunnel syndrome. Methods Conducting nerve conduction velocity and electromyography detection to 85 cases of diabetic patients,to calculate the ratio of the diabetic peripheral nerve damage and the cubital tunnel syndrome. Results In the 85 cases of diabetic patients, 36 cases are peripheral nerve damage and 11 cases are cubital tunnel gyndrome （12.9 %）, in which 7 cases are peripheral nerve damage with cubital tunnel syndrome,4 cases are pure cubital tuonel syndrome, and 3 cases are bilateral damage. Among the patients with cubital tunnel syndrome, there are 8 cases appear a cubit under the movement was slow nerve conduction velocity（compared with upper arm〉10m/s）and wrist-the little finger sensory nerve reduce potential amplitudes,3 cases appear under the campaign on a cubits was lower （〉 50% potential ampli- tudes） with the little finger bone, the first abductor muscle between muscle appear spontaneously potential. Conclusion It is not rare that the diabetic patients are in concurrent with cubits tunnel syndrome, there may be provided the mechanism. Detecting nerves conduction velocity Was helpful to find out cubital tunnel syndrome in diabetes mellitus so treatment could be made in time.
