目的　研究热性惊厥患儿的复发危险因素及预后情况。方法　结合 98例热性惊厥患儿的临床及脑电图资料 ,研究其复发、转为癫疒间和出现智力障碍及行为异常的情况。结果　复发共 5 2例 (5 3.0 % ) ,复发危险因素与惊厥家族史、初次发作体温 <38 5℃、初次发作年龄 <1岁及复杂型热性惊厥有关 (P <0 .0 1) ;热性惊厥转为癫疒间共 2 0例 (2 0 .4% ) ,转为癫疒间的危险因素与复杂型热性惊厥、初次发作年龄 <1岁、热性惊厥反复发作有关 (P<0 .0 1) ;发生智力障碍及行为异常 2例 (2 .0 % ) ,说明热性惊厥患儿绝大部分预后较好 ,智力低下及行为障碍发生率低。结论　对有复发危险因素及转为癫疒间危险因素的患儿 ,应密切随访 ,采取适当的干预措施。 Objective To study the risk factors and prognosis of relapse in children with febrile seizures. Methods The clinical and electroencephalographic data of 98 children with febrile seizures were used to study the relapse, changes to epilepsy, mental retardation and behavioral disorders. The relapse risk factors were related to family history of seizure, body temperature of initial seizure <38 5 ℃, primary seizure age <1 year and complicated febrile convulsion (P <0.01); Fever seizures into epilepsy a total of 20 cases (20.4%), the risk factors for epilepsy and complex febrile seizures, the first attack age <1 year old, repeated episodes of febrile seizures (P <0. 01). There were 2 cases (2. 0%) of mental retardation and behavioral abnormalities, indicating that most children with febrile seizures had better prognosis, lower mental retardation and lower incidence of behavioral disorders. Conclusion For children with recurrent risk factors and risk factors for epilepsy, follow-up should be closely followed and appropriate interventions should be taken.
