OBJECTIVE
To define the role of the EEG in predicting recurrence of febrile seizures (FS) in children after a first FS.
METHODS
Children with a first simple or complex FS who underwent EEG at our hospital were retrospectively enrolled. EEG recordings were classified in three groups: normal, abnormal (slow activity or epileptiform discharges), and pseudo-petit mal discharge (PPMD) pattern. Children were followed-up for at least three years.
RESULTS
A total of 126 patients met the entry criteria, and 113 of them completed the follow-up. Risk of FS recurrence decreased linearly with increasing age (-2% per month). The risk was higher among patients with PPMD pattern (absolute risk 86%, adjusted relative risk 2.00) and abnormal EEG (epileptiform discharges: absolute risk 71%, adjusted relative risk 2.00; slow activity: absolute risk 56%, adjusted relative risk 1.44), compared with those with normal EEG (absolute risk 41%).
CONCLUSIONS
PPMD and abnormal EEG should be considered as an independent risk factor for FS recurrence.
目的
明确脑电图（EEG）在预测儿童首次热性惊厥（FS）后复发中的作用。
方法
回顾性纳入在我院接受EEG检查的首次发生单纯性或复杂性FS的儿童。EEG记录分为三组：正常、异常（慢波活动或癫痫样放电）和假小发作放电（PPMD）模式。对儿童进行至少三年的随访。
结果
共有126例患者符合纳入标准，其中113例完成随访。FS复发风险随年龄增长呈线性下降（每月-2%）。与EEG正常的患者（绝对风险41%）相比，PPMD模式患者（绝对风险86%，校正相对风险2.00）和EEG异常（癫痫样放电：绝对风险71%，校正相对风险2.00；慢波活动：绝对风险56%，校正相对风险1.44）患者的复发风险更高。
结论
PPMD和EEG异常应被视为FS复发的独立危险因素。
