目的:评价体感诱发电位在脊髓型颈椎病术中的应用价值.方法:对47例脊髓型颈椎病患者行术中SEP监测,以JOA评分评定临床疗效,比较手术前后JOA评分的变化,分析术中SEP变化和临床疗效之间的关系.结果:43例患者术中SEP无明显变化,3例患者术中SEP有一过性波幅下降,潜伏期无明显改变,术后患者恢复良好;1例患者术中始终未记录到右侧肢体SEP,术后神经功能无明显改善.术后患者JOA评分明显改善.结论:术中SEP监测有助于了解脊髓功能,对脊髓型颈椎病的预后有参考价值.%Objective :To determine the role of intraoperative somatosensory evoked potential(SEP) monitoring in cervical spondylotic myelopathy. Methods:Intraoperative SEP was performed in 47 patients undergoing cervical spondylotic myelopathy and the results were estimated by JOA .scores for the variation of the JOA scoring before and after the procedure besides the changes between intraoperative SEP and clinical outcomes.Results:No significant intraoperative change of SEP was found in the 43 patients, and yet, temporary decrease in amplitude was seen in 3. There was no change in the latency, and these patients had good recovery. SEP failed to be kept in the right lateral limbs of one patient during the operation, thus resulting in no neurological improvement. Generally, postoperative JOA scores were improved significantly in the total patients.Conclusion:Intraoperative SEP monitoring is helpful in testing the function of spinal cord and has implication in estimating the prognosis of cervical spondylotic myelopathy.
