摘要
目的：观察常用麻醉药物及控制性降血压对猴皮层体感诱发电位（ＣＳＥＰ）、脊髓体感诱发电位（ＳＳＥＰ）和经颅磁刺激运动诱发电位（ＭＥＰ）的影响，评价诱发电位术中监测的作用及影响因素。方法：选用１０只健康猴直接模拟脊柱手术中的麻醉及控制性降压等操作，诱发电位监测。结果：ＣＳＥＰ受多种麻醉药物及控制性降压影响，特别是氯胺酮和异氟醚；ＳＳＥＰ受影响最小。结论：单独使用ＣＳＥＰ监测必须与麻醉密切配合，否则既不稳定又不可靠。
Objective:In order to observe the influence of anesthetic managements and blood pressure on cortical somatosensory evoked potential(CSEP),spinal somatosensory evoked potential(SSEP) and motor evoked potential(MEP)during the operation.Method:10 monkeys were anesthetized to mimic the procedures of spinal surgery monitored by CSEP,SSEP and MEP.Result:Different anesthetic agents and other managements could affect CSEP prominantly,MEP had moderat changes,but SSEP could hardly vary.Conclusion:The use of CSEP alone is neither stable nor reliable.SSEP is the best method to monitor the spinal cord function,although it is inconvenient to put the epidural electrades.
