摘要
目的探讨脑干及其周围手术损伤与脑干听觉诱发电位(BAEP)和体感诱发电位(SEP)不同指标之间的关系,找出神经功能损伤敏感的电生理指标。方法对23例脑干肿瘤病人进行手术中BAEP和SEP连续监测。结果脑干及其周围手术操作均可以引起BAEP、SEP的改变。SEP的N13 N20中枢传导时间(CCT)和N20潜伏期及波幅的变化和BAEPV波潜伏期(PL)、ⅢⅤ、Ⅰ-Ⅴ峰间潜伏期(IPL)的变化均是术中监护的关键指标。结论动态分析BAEP、SEP各敏感指标的变化。
Objective To observe the influence of operative injury near brainstem on auditory brainstem evoked potentials (BAEP) and somatosensory evoded potentials(SEP), in order to find sensitive eletrophysiological indexes for neurofunction injury.Methods The 23 patients were monitored continuously during brainstem operation with BAEP,SEP.Results The operation in or near brainstem could induce the change of BAEP and SEP. The parameters changed significantly during intraoperation evoked potentials monitoring were N20 wave and N13 N20 central conduction time (CCT) in SEP, V peak latency, Ⅲ Ⅴ,Ⅰ Ⅴ interpeak latency in BAEP respectively.Conclusions It is important to monitor evoked potentials in brainstem operation surgery.
