The aim of intraoperative monitoring methods is to obtain early information about central nervous function during critical phases of the operation. To this end it can be useful to accept modifications of the method or the technical parameters such as changes of the electrode positions, of the system's bandpass, the analysis time or the number of sweeps used for averaging. Additionally emphasis is laid upon the fact that there is no knowledge concerning the critical changes of potential which might indicate functional disturbances or impending postoperative neurological deficits. At the present time intraoperative EP-Monitoring is not an established method for clinical use. Evidence is lacking that supervision of the operation by these means results in a reduced operation risk.
术中监测方法的目的是在手术的关键阶段获取有关中枢神经功能的早期信息。为此，接受方法或技术参数的修改可能会有所帮助，例如电极位置的改变、系统带通、分析时间或用于平均的扫描次数。此外，需要强调的是，目前尚不清楚哪些潜在的关键变化可能表明功能障碍或即将出现的术后神经功能缺损。目前，术中诱发电位监测并非临床常用的既定方法。缺乏证据表明通过这些手段对手术进行监测能降低手术风险。
