摘要 目的探讨神经肌电图(EMG)检测对臂丛神经损伤的诊断价值。方法选择2012年8月至2013年8月河南省南阳南石医院收治的臂丛神经损伤患者50例,均经磁共振成像(MRI)、术前EMG和术中体感诱发电位(SEP)检查,比较诊断符合率。结果术前神经EMG检查诊断上臂丛损伤、下臂丛损伤及全臂丛损伤的结果与手术探查结果的一致性程度极好,Kappa值均大于0.75。术前神经EMG检查对臂丛神经损伤定性诊断的符合率为82.2%(125/152),显著高于MRI诊断的68.4%(104/152),差异有统计学意义(P<0.05),与SEP诊断符合率80.9%(123/152)相当,差异无统计学意义(P>0.05)。结论术前神经EMG检查可有效提高臂丛神经损伤的诊断符合率和正确判断损伤性质,减少漏诊。 Objective To analyze the value of electromyography(EMG) detection in diagnosis of bra-chial plexus injury.Methods A total of 50 patients with brachial plexus injury in Nanshi Hospital from Aug.2012 to Aug.2013 were included in the study.All were checked by magnetic resonance imaging (MRI),preoperative EMG and intraoperative somatosensory evoked potential(SEP) examination.The diag-nostic accordance rate was compared.Results The coincidence rate of preoperative EMG examination in the diagnosis of nerve types in brachial plexus injury was very good,all Kappa 〉0.75.The coincidence rate of preoperative neurological EMG in the qualitative diagnosis of brachial plexus injury was 82.2%(125/152), which was significantly higher than 68.4% (104/152) of MRI diagnosis and equivalent to SEP diagnosis 80.9%(123/152).The difference was not statistically significant(P 〉0.05).Conclusion Preoperative EMG examination can effectively improve the coincidence rate in diagnosis of brachial plexus injury , help judge the injury nature correctly,and reduce misdiagnosis.
