癫痫患者脑电图监测中表面电极与表面电极加T1/T2附加电极的应用效果对比

Comparison of the application effect of surface electrode and surface electrode plus T1/T2 additional electrode in EEG monitoring of epileptic patients

目的:对比分析癫痫患者24 h视频脑电图监测中表面电极与表面电极加T1/T2附加电极的应用效果。方法:选取琼海市人民医院2021年1月至12月收治的55例癫痫患者作为研究对象。在患者癫痫发作间期对其实施24 h视频脑电图监测,分别给予表面电极与表面电极加T1/T2附加电极监测,记录并比较各导联放电的最大值、平均值、检出频率。结果:T1/T2附加电极放电波幅最大值、平均值最高,后颞电极放电检出频率最高,为74.5%。放电检出频率居于前三位的是:后颞74.5%、附加电极69.0%、前颞65.4%,均显著高于其他位置电极(P<0.05)。最大放电波幅居于前三位的是:附加电极150μv、前颞120μv、后颞100μv。本研究未记录到局限于附加电极的放电。结论:癫痫患者行24 h视频脑电图监测时,与单独应用表面电极相比,应用表面电极加T1/T2附加电极可进一步提高癫痫发作间期放电的检出频率,具有一定的临床意义。

Objective:To compare and analyze the application effect of surface electrode and surface electrode plus T1/T2 additional electrode in 24 h video EEG monitoring of patients with epilepsy.Methods:Fifty-five epileptic patients admitted to Qionghai People’s Hospital from January to December 2021 were selected as subjects.24 h video electroencephalogram monitoring was carried out during the interseizure period of patients.Surface electrode and surface electrode plus T1/T2 additional electrode were respectively monitored,and the maximum,average and detection frequency of discharge in each lead were recorded and compared.Results:The maximum and average discharge amplitude of T1/T2 additional electrode were the highest,and the detection frequency of posterior temporal electrode was the highest(74.5%).The top three discharge detection frequencies were:posterior temporal 74.5%,additional electrode 69.0%and anterior temporal 65.4%,all of which were significantly higher than other electrodes(P<0.05).The top three largest discharge amplitudes were:additional electrode 150μv,anterior temporal 120μv and posterior temporal 100μv.No discharge limited to the additional electrode was recorded in this study.Conclusion:Compared with the single application of surface electrode,the application of surface electrode plus T1/T2 additional electrode can further improve the detection frequency of interseizure discharge in patients with epilepsy during 24 h video EEG monitoring,which has certain clinical significance.
