To evaluate the clinical utility of the ambulatory electroencephalogram (AEEG) in children.
Data from 199 consecutive referrals for a paediatric AEEG were reviewed retrospectively. Information was gathered on various aspects of the referral process, the characteristics of the children referred and the reasons for referral. Clinical utility was calculated as the percentage of cases in which the investigation provided useful information with respect to the question asked of the test.
The AEEG was useful in 64.8% cases overall. In 51.4% of cases the reason for referral was to capture events, however the test was only useful in 42.6% of these. The most common reason for an unsuccessful investigation was failure to capture events (55.6%). Suspected encephalopathy with status epilepticus during sleep (ESES) was the indication in a substantial number of cases (38.6%), and the investigation was useful in most of these (97.5%). Technical issues were only responsible for 7 (9.7%) of unsuccessful studies.
The paediatric AEEG was useful in two thirds of patients. Failure to capture events appears to be the most significant limiting factor. The AEEG is very useful in investigating suspected ESES.
评估动态脑电图（AEEG）在儿科中的临床应用价值。
回顾性分析了 199 例儿科 AEEG 转介的连续数据。收集了转介过程的各个方面、被转介儿童的特征以及转介原因等信息。临床实用性的计算方法是将调查提供的有用信息占所提出问题的百分比。
AEEG 在总体上有 64.8%的病例是有用的。51.4%的转介原因是为了捕捉事件，但该测试在这些病例中只有 42.6%是有用的。调查不成功的最常见原因是未能捕捉到事件（55.6%）。疑似睡眠中癫痫持续状态（ESES）的脑病是大量病例（38.6%）的指征，而该检查在大多数情况下是有用的（97.5%）。技术问题仅导致 7 例（9.7%）不成功的研究。
儿科 AEEG 在三分之二的患者中是有用的。未能捕捉到事件似乎是最主要的限制因素。AEEG 在调查疑似 ESES 方面非常有用。
