目的分析单纯性热性惊厥的病因和临床特点。方法 76例单纯性热性惊厥患儿,回顾性分析其临床资料,观察患儿体温变化、抽搐持续时间、总计抽搐发作次数、抽搐后意识恢复状态、是否存在异常神经症等情况。结果体温突然升高是导致单纯性热性惊厥发作的主要原因。入组患儿多在早期发热时体温骤升状态下即伴有单纯性热性惊厥,患儿一次发热期间基本不会出现连续抽搐症状,且症状持续时间相对较短(≤10 min),抽搐症状纠正后患儿意识恢复用时较短,且未出现异常神经征。经过对症治疗后76例患儿体温均恢复正常,7 d后脑电图扫查结果无异常。结论单纯性热性惊厥大多为一过性发作,与患儿高热状态存在密切关联,经积极治疗后即可快速恢复,预后大多良好。
Objective To analyze the etiology and clinical features of simple febrile seizures. Methods A total of 76 children with simple febrile seizures were retrospectively analyzed. The changes of body temperature, the duration of convulsions, the total number of convulsions, the state of recovery after convulsion, and the presence of abnormal neurosis were observed. Results A sudden increase in body temperature is the main cause of simple febrile seizures. Infants in the group were mostly accompanied by simple febrile seizures under the sudden warming of body temperature in the early stage of fever. There was almost no convulsive symptom during the first fever in children and the duration of symptoms was relatively short (≤10 min) Children with recurrent symptoms after recovery of time is shorter, and no abnormal neurological symptoms. After symptomatic treatment of 76 cases of children were returned to normal body temperature, 7 days after EEG scan results were normal. Conclusions Most of simple febrile seizures are transient attacks, which are closely related to the high fever in children. After active treatment, they can be quickly recovered with good prognosis.
