摘　　要：目的评估膈神经传导功能测定方法的临床应用价值。方法对292例臂丛神经损伤患者进行膈神经诱发电位的检测，根据积水潭医院肌电图室建立的正常值将其分为传导功能正常组与传导功能异常组，比较2组膈神经诱发电位的潜伏期和波幅。结果传导功能正常组膈神经诱发电位的潜伏期较异常组明显降低，波幅较异常组明显增加，差异有统计学意义（P〈0．05）。结论膈神经运动传导功能测定方法简便、易行，安全可靠，是一种临床了解膈神经功能的可靠方法。Objective To investigate the clinical value of measurement of phrenic nerve conduction function. Methods Evoked potentials of the phrenic newe were measured in 292 patients with brachial plexus injuries. According to the normal value that was established in the electromyogram in our hospital, we divided them into normal and abnormal evoked potential groups, and then, the latent period and wave amplitude in the two groups were compared. Results Compared to those in the normal potential group, the latent period in abnormal group was significantly high and wave amplitude low（P〈0.05）. Conclusion Measurement ofphrenic nerve conduction is convenient, safe, and reliable to evaluate the conduction function of the phrenic nerve.
