目的初步探讨颅内动脉瘤手术中躯体感觉诱发电位、脑干听觉诱发电位及运动诱发电位的临床应用价值.方法在16例动脉瘤手术中开展诱发电位监测,观察术中电生理信号改变与术后神经功能状态的关系.结果 11例术中未出现电生理信号异常改变,5例术中出现了异常信号,其中信号未能恢复正常的4例术后均出现新发神经功能障碍.结论诱发电位监测可实时了解颅内动脉瘤手术中有无脑缺血所致的神经功能障碍,对指导手术及评估预后均有重要意义.

Objective To explore the application of intraoperative neuroelectrophysiological monitoring on somatosensory evoked potentials (SEP), brainstem auditory evoked potentials (BAEP) and motor evoked potentials (MEP) during intracranial aneurysm surgery.Methods SEP, BAEP or MEPs were monitored during operations on 16 patients with intracranial aneurysms.The relationship between the intraoperative changes of electrophysiological signals and the postoperative outcomes of neurological deficits was evaluated.Results 11 patients without abnormal intraoperative electrophysiological signal changes demonstrated no new neurological deficits after surgery.However, in the left 5 patients, abnormal changes of intraoperative electrophysiological signals were detected.Among these 5 patients, 4 with abnormal electrophysiological signals which were not recovered intraoperatively demonstrated new developed functional deficits immediately after surgery.Conclusion During intracranial aneurysm surgery, the monitoring on SEP, MEP and BAEP is beneficial not only to timely detecting neurological functional deficits resulted from intraoperative cerebral ischemia, but also to properly guiding surgical manipulation, and to reliably predicting postoperative outcome as well.
