摘要
目的:探讨神经电生理在外伤性臂丛神经损伤诊断中的临床应用价值。方法:应用丹迪KEYPOINT肌电/诱发电位仪对43例外伤性臂丛神经损伤患者进行神经传导速度、诱发定位检查。结果:全臂丛神经损害6例,其中5例正中神经、尺神经、桡神经、肌皮神经、腋神经MCV及SCV均未引出波形,F波消失,患肢体感诱发电位引不出;1例正中神经、尺神经、桡神经、肌皮神经、腋神经MCV明显减慢,波幅明显降低,潜伏期延长,SCV及F波异常。臂丛上干损伤18例,其中肌皮神经、腋神经MCV减慢,波幅下降14例;桡神经、腋神经、肌皮神经MCV减慢,波幅降低4例。臂丛下干损害19例,正中神经、尺神经MCV明显减慢,波幅明显降低,SCV减慢,F波异常者15例;正中神经、尺神经、桡神经MCV减慢4例。结论:神经电生理检查对于正确判断臂丛神经损伤的部位、程度以及决定治疗方案有着重要的临床意义,神经电生理可作为外伤性臂丛神经损伤首选检查。
Objective ：To explore the neural electrophysiology in traumatic brachial plexus injury and its clinical value. Methods： Nerve conduction velocity, induced positioning check for 43 cases of traumatic brachial plexus injury patients by Dundee EYPOINT EMG / evoked potential instrument. Results ： Six cases brachial plexus damage, including five cases of the median nerve,ulnar nerve, radial nerve,musculocutaneous nerve, axillary nerve MCV and SCV at the end leads wave- form, F wave disappeared, suffering from the limb flu evoked potentials was absent;1 Examplemedian nerve, ulnar nerve, radial nerve, musculocutaneous nerve, axillary nerve MCV slowed down, volatility is significantly reduced latency, the SCV and F-wave abnormalities. Upper trunk of brachial plexus injury in 18 cases, musculocutaneous nerve, axillary nerve MCV slow down ,volatility dropped 14 cases ;radial nerve, axillary nerve, musculocutaneous nerve MCV slow down,volatility low- er four cases. Lower trunk of brachial plexus damage to the 19 cases, the median nerve, ulnar nerve MCV slowed down, volatility is significantly reduced,SCV slow down the F-wave abnormalities in 15 patients ; median nerve, ulnar nerve, ra- dial nerve MCV slow down the four cases. Conclusions：The neurophysiological examination has clinical significance to determine treatment options for brachial plexus injury patients, the neurophysiological can be first choice for traumatic bra- chial plexus injury patients.
