脊柱手术中体感诱发电位监护

目的：研究体感诱发监护脊柱手术的监测技术。方法：采用皮层体感秀发电位（CSEP）监测90例手术，记录每个重要手术步骤前、中、后CSEP，观察基分析原因。结果；麻醉深度与麻药咱类对CSEP有影响，其中以异氟醚为明显。脊柱手术中的操作均可引起CSEP改变。1例CSEP波形离散持续5min的患者术后出现可逆性脊髓损伤。结论：CSEP有简便、灵敏和及时监护等特点，波幅下降50％，潜做期延长10％是术中监护的预警值，对同时出现波形了散2min应予以高度重视。

Application of Cortical Somatosensory Evoked Potential Monitoring in Spinal Surgery

Objective: To study the technique application of cortical somatosensory evoked potential(SEP) monitoring in order to preventing intraoperative neurological complication.Methods:90 cases with spinal abnormality underwent surgical management monitored by CSEP.every important surgical step was monitored by observing and comparing the changes of amplitude and latency of CSEP.Result:Anesthetic agents could affect CSEP, surgical processes including hooking,rod distraction and compression also affect the amplitude and latency of CSEP,one patient who had abnormal types of CSEP during operation for 5 minutes had partial dysfunction of spinal cord post operative temporarily.Conclusion:CSEP is an ideal monitoring method in spinal surgery,amplitude decreases by 50% and latency prolong by 10% will alarm for risk of damage to the spinal cord,meanwhile,alarm situation combine with abnormal type CSEP for more than two minutes is a high risk of neurologic impairment.
