热性惊厥患儿485例的临床特征和脑电图分析

Analysis of clinical features and electroencephalograms of 485 children with febrile convulsion

目的探讨热性惊厥患儿的临床特征和脑电图特点。方法对485例热性惊厥患儿临床资料和脑电图进行回顾性分析。结果 485例热性惊厥患儿≤3岁者395例(81.4%);惊厥时体温在38℃以上者469例(96.7%),其中≥39℃者326例(67.2%),有家族史者216例(44.5%);首次发作1-3 d内脑电图异常299例(61.6%),惊厥发作后10-14 d脑电图异常171例(39.3%)。脑电图异常171例,其中>3岁58例(58/88,占65.9%),体温≤38℃者11例(11/16,占68.8%),发作次数>2者62例(62/83,占74.7%)。结论热性惊厥患儿的发作与年龄、体温、惊厥家族史有关;脑电图异常与年龄、体温、发作次数有关。

Objective To investigate the clinical features and electroencephalogram（EEG） of children with febrile convulsion（FC）.Methods The data of the clinical characteristics and EEG of 485 children with FC were analyzed retrospectively.Results Of 485 children,395（81.4%） were below three years old.The temperature was more than 38 ℃ in 469 children（96.7%） when febrile convulsion,including 230 children（67.2%）with the temperature ≥39 ℃.Of 485 children,216 children（44.5%）had family history.Abnormal EEG was found in 299 children（61.6%）with the first FC in 1-3 d,171 children（39.3%）after the episode for 10-14 d.A total of 171 children were found abnormal EEG,including 58（58/88,65.9%）children above three years old,11 children（11/16,68.8%）with the temperature ≤38 ℃ and 62（62/83,74.7%）children with episode more than twice.Conclusion FC in children is correlated with age,temperature and family history.The abnormal EEG of children is correlated with age,temperature,and the times of episode.
