目的探讨高热惊厥对脑电图的影响。方法对161列高热惊厥患者的脑电图和相关资料进行回顾分析。将161例高热惊厥患者按不同年龄分为三组:A 组(2～4岁),B 组(5～7岁),C 组(8～9岁),并将三组的脑电图结果进行比较。结果退热一周后:①脑电图总异常率为47.2%(其中轻度异常21.1%,癎样改变26.1%)。②A组(2～4岁)的脑电图异常率52.1%和 C 组(8～9岁)的脑电图异常率91.6%,呈明显增高。退热一个月后:①有18例轻度异常的脑电图恢复到正常水平,其余的均无明显变化。②脑电图的异常率与不同的热惊年龄、不同的热惊阈值、首次热惊发作和多次热惊发作有关。③A组(2～4岁)的热惊低阈值率和热惊复发率分别为66.3%和86.6%,是三组中最高的。结论高热惊厥的发作可导致脑损伤,脑电图检查对高热惊厥的脑损伤和预后的判断是一个很有用的监测。
Objective To investigate the effects of febrile seizures on electroencephalogram. Methods The EEG and related data of 161 patients with febrile seizures were retrospectively analyzed. 161 patients with febrile seizures were divided into three groups according to different ages: group A (2-4 years old), group B (5-7 years old) and group C (8-9 years old). EEG results Compare. Results a week after the antipyretic: ① total abnormal EEG was 47.2% (mild abnormalities of 21.1%, 26.1% change of samples). ② The frequency of EEG abnormalities in group A (2 ~ 4 years old) was 52.1% and that in group C (8 ~ 9 years old) was 91.6%. After a month of fever: ① 18 cases of mild abnormal EEG returned to normal levels, the rest had no significant change. ② abnormal rate of EEG and different hot shock age, different levels of alarm threshold, the first episode of heat shock and multiple heat shock related. ③A group (2 to 4 years old) the threshold value of thermal shock and the rate of the hot shock were 66.3% and 86.6%, respectively, which were the highest among the three groups. Conclusions The onset of febrile seizures can lead to brain injury. EEG examination is a useful monitoring of brain injury and prognosis in febrile seizures.
