高热惊厥是儿科常见症状。统计表明,3%～4%的儿童至少发生过1次高热惊厥.小儿惊厥的发生率是成人的10～15倍。这是因为婴幼儿的大脑发育不完善,对刺激的分析鉴别能力差.弱的刺激就可使大脑运动神经元异常放电,引起惊厥。小儿高热惊厥的临床表现.可分为简单型和复杂型两种。简单型的特点:年龄在半岁至4岁之间。5岁以后少见。多是由于感冒急性发热引起,惊厥大都发生在体温骤升达到38.5℃～39.5℃时。发作时意识丧失。全身性对称性
Fever convulsions are common pediatric symptoms. Statistics show that 3% to 4% of children had at least one febrile seizure.The incidence of pediatric seizures is 10 to 15 times that of adults. This is because infants and young children’s brain development is not perfect, the analysis of the ability to identify poor stimulation.Weak stimulation can make abnormal motor neurons in the brain discharge, causing convulsions. Clinical manifestations of pediatric febrile seizures can be divided into two types of simple and complex. Simple features: the age of six months to four years old. After 5 years old rare. Mostly due to the acute fever caused by a cold, convulsions occur mostly in the body temperature rose to 38.5 ℃ ~ 39.5 ℃. Loss of consciousness at onset. Systemic symmetry
