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，评价术中监测诱发电位的作用及影响因素。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酸，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，SSEP是最佳监测指标。
To oborve the influence of anesthetic managements and blood pressure on monkeys'cortical somatosensory evoked potentials(CSEP),spinal somatosensory evoked potenteal(SSEP).and to motor evoked potential (MEP)and to evaluate ovoked potential in monitoring spinal cord function during operation. Methods: 10 monkeys were anesthetized with dif ferent agents to mimic spinal surgery monitored by CSEP,SSEP and MEO.Results:Lots of facts could affect CSEO greatly,butSSEP could hardly vary with different anesthetic agents and oter managements.Conclusions:The use of CSEP alone ins neitherstable nor reliable. SSEP is the beast metod in moitoring spinal cord function,although it is unconvenient to put the eqiduralpoles.
