Background
The primary objective of this study was to investigate the utility of limited-montage electroencephalography (EEG) for seizure detection in children. We also aimed to determine whether the detection rate differed among different montage patterns.
Methods
This study was carried out between November 2019 and October 2020 at a tertiary children's hospital in Japan. The subjects were inpatients in the pediatric intensive care unit who had an epileptic seizure during EEG monitoring. Each patient's EEG record, consisting of a 15-minute recording during an epileptic seizure and a 15-minute recording in the absence of an epileptic seizure, was extracted from the medical charts. The EEG data were then analyzed using six, limited-montage coverage patterns: (1) Fp1-C3, Fp2-C4, (2) Fp1-O1, Fp2-O2, (3) Fp1-T3, Fp2-T4, (4) C3-O1, C4-O2, (5) C3-T3, C4-T4, and (6) O1-T3, O2-T4. The sensitivity and specificity of each montage for seizure detection was analyzed.
Results
One hundred thirty-two EEG data points from 11 patients were examined. Sensitivity and specificity were the highest for Fp1-O1 and Fp2-O2 at 73% and 91%, respectively. Overall, the montage covering the frontopolar area had the highest detection rate, followed by the montage covering the occipital, central, and temporal areas.
Conclusion
Limited-montage EEG identified seizures in children hospitalized in the intensive care unit, but the detection rate differed by montage coverage. The detection rate was highest in the montage covering the frontopolar area.

有限蒙太奇脑电图在儿童癫痫发作检测中的应用
背景
本研究的主要目的是调查有限蒙太奇脑电图 (EEG) 在儿童癫痫发作检测中的效用。我们还旨在确定不同蒙太奇模式之间的检测率是否不同。
方法
这项研究于 2019 年 11 月至 2020 年 10 月在日本一家三级儿童医院进行。受试者是儿科重症监护病房的住院患者,他们在脑电图监测期间癫痫发作。从病历中提取每位患者的脑电图记录,包括癫痫发作期间的 15 分钟记录和没有癫痫发作时的 15 分钟记录。然后使用六种有限蒙太奇覆盖模式分析 EEG 数据:(1) Fp1-C3、Fp2-C4、(2) Fp1-O1、Fp2-O2、(3) Fp1-T3、Fp2-T4、(4 ) C3-O1、C4-O2、(5) C3-T3、C4-T4 和 (6) O1-T3、O2-T4。分析了癫痫发作检测的每个蒙太奇的敏感性和特异性。
结果
检查了来自 11 名患者的 132 个 EEG 数据点。Fp1-O1 和 Fp2-O2 的灵敏度和特异性最高,分别为 73% 和 91%。总体而言,覆盖额极区域的蒙太奇检测率最高,其次是覆盖枕骨、中央和颞叶区域的蒙太奇。
结论
有限蒙太奇脑电图识别了重症监护病房住院儿童的癫痫发作,但检出率因蒙太奇覆盖范围而异。在覆盖额极区域的蒙太奇中检测率最高。
