目的 探讨复杂性热性惊厥 (FC)发作后脑电图 (EEG)的异常情况。方法 对近三年多来我科住院病人中出院诊断为复杂性FC且发作后 7～ 10d作过EEG的病例进行分析。结果 38例患儿符合复杂性FC诊断标准 ,38例中 ,病前有神经精神方面异常的 12例 ,34例有一项复杂性FC因素 ,其中惊厥时间长 2 8例 ,反复发作 4例 ,局限性发作 2例 ;4例有二项复杂性FC因素 ,其中惊厥时间长并反复发作 3例 ,限局性发作并惊厥时间长 1例。所有患儿均作剥夺睡眠EEG ,EEG正常 2 5例 ,异常 13例 (34 2 % ) ,13例中 9例FC前有神经精神方面异常 ,占异常例数的 6 9 2 %。 13例中惊厥时间长 6例 ;反复发作 1例 ;惊厥时间长并反复发作 3例 ,局限性发作 2例 ;局限性发作并惊厥时间长 1例。结论 FC前已有神经精神异常患儿的EEG异常率明显高于神经系统正常的患儿 ,EEG检查对既往有潜在性脑部病变者有一定作用 ,尤其是伴脑发育落后或惊厥前有神经系统损害、惊厥时间长或局限性发作后遗有神经系统体征者 ,对EEG有异常的应给予重视 ,动态观察 ,做EEG随访
Objective To investigate the anomalies of EEG after the onset of complex febrile seizures (FC). Methods In the past three years or so, the inpatients in our department were diagnosed with complicated FC and hospitalized with EEG from 7 to 10 days after the attack. Results 38 cases of children with complex diagnostic criteria of FC, 38 cases, premorbid neuropsychological abnormalities in 12 cases, 34 cases had a complex FC factors, including convulsions for a long time 28 cases, recurrent in 4 cases, the limitations 2 cases of sexual seizures; 4 cases had two complex FC factors, including convulsions for a long time and recurrent episodes in 3 cases, the limited seizure and convulsive time in 1 case. All children were deprived of sleep EEG, EEG normal 25 cases, abnormal 13 cases (34 2%), 13 cases of 9 cases of FC before neuropsychiatric abnormalities, accounting for 69.2% of the abnormal cases. 13 cases of convulsions for a long time in 6 cases; repeated attack in 1 case; convulsions for a long time and repeated attacks in 3 cases, 2 cases of localized attacks; limitations of seizures and convulsions for a long time. Conclusion The abnormal EEG abnormalities in children with neuropsychiatric abnormalities before FC were significantly higher than those in normal nervous system patients. EEG examination had some effect on the patients with latent brain lesions, especially those with brain development or convulsion System damage, long time of seizures or limitations after the onset of neurological signs were left, the abnormal EEG should pay attention to dynamic observation, do EEG follow-up
