背景：STATNet电极组是一种非脑电(EEG)技术人员在经过最低限度的培训后即可使用的系统。这项研究的主要目标是评估与传统脑电相比，StatNet记录的质量和可靠性。方法：10个月以上，19例疑似非惊厥性癫痫持续状态的患者来自大学医院急诊室。每个患者都接受了由训练有素的癫痫专家进行的StatNet EEG和由注册技术人员进行的常规EEG。我们以盲法比较了从脑电顺序到建立时间、采集开始时间、伪影数量和异常检测的时间范围。比较采用非参数Mann-Whitney两样本t检验。用Kappa评分评估其可靠性。结果：患者平均年龄6116.3岁(25~93岁)。对于异常发现的检测，观察者间一致性为0.83(StatNet)和0.75(常规EEG)。两组均有10%(2/19)的患者出现非惊厥性癫痫持续状态。从申请脑电到采集脑电的时间，STATNET组(22.4±2.5min)明显短于传统EEG组(217.7±44.6min；p
Background: The StatNet electrode set is a system that can be applied by a non-electroencephalogram (EEG) technologist after minimal training. The primary objectives of this study are to assess the quality and reliability of the StatNet recordings in comparison to the conventional EEG. Methods: Over 10 months, 19 patients with suspected nonconvulsive status epilepticus were included from university hospital emergency settings. Each patient received a StatNet EEG by a trained epilepsy fellow and a conventional EEG by registered technologists. We compared the studies in a blinded fashion, for the timeframe from EEG order to the setup time, start of acquisition, amount of artifact, and detection of abnormalities. The nonparametric Mann-Whitney two-sample t test was used for comparisons. The kappa score was used to assess reliability. Results: Mean age of patients was 6116.3 (25-93) years. The inter-observer agreement for detection of abnormal findings was 0.83 for StatNet and 0.75 for conventional EEG. Nonconvulsive status epilepticus was detected in 10% (2/19) in both studies. The delay from the time of EEG requisition to acquisition was shorter in the StatNet (22.4 +/- 2.5 minutes) than the conventional EEG (217.7 +/- 44.6 minutes; p
