体感诱发电位在脊髓脊柱手术中的监测

目的评价脊髓脊柱手术中躯体感觉诱发电位（SEP）监测对脊髓功能的判断作用。方法对14例脊髓脊柱手术前、中、后SEP监测，术中为连续监测。站票摘除椎管内占位病变、脊柱手术中撑开侧弯凹侧、凿除椎管狭窄的推板时SEP出现显著改变，在手术结束前均恢复正常。给哈SEP术中监测有连续、敏感、准确的优点。

SEP Monitoring in Spinal Cord and Spinal Surgery

Objective To assess whether SEP monitoring contribute to the identification of spinalcord function. Methods 14 patients with spinal cord or spinal diseases have been monitored by SEP be fore, during and after operations. Introperative SEP was monitored continuously. Results The resection of intravertebral tumor and the correction of the spinal curve and the laminectomy with the presence of spinal stenosis resulted in the significant changes of SEP, these changes became normal before the end of surgery. Conclusion The continous, intraoperative SEP monitoring was sensitive and correct.
