When acute infectious diseases such as upper respiratory tract infection, acute tonsillitis, pneumonia and early onset of infectious diseases are hyperthermia, increased excitability of heat stroke and convulsions caused by neurological dysfunction are called hyperthermia convulsions. Its incidence is very high, according to the survey, 5%-8% of children have had a febrile convulsion, accounting for 30% of the causes of convulsions in childhood. The characteristics are: 1) the age of prevalence is 6 months to 3 years, the frequency of seizures decreases after the age of 3 years, and rarely occurs in children under 6 months and above 6 years; 2) upper respiratory tract infections cause 60% of the cases, often occurring at the beginning of the disease when the body temperature rises sharply, the temperature often reaches 39-40 ℃, the higher the body temperature, the more chances of convulsions; 3) generalized convulsions accompanied by impaired consciousness, but after the convulsions stop, consciousness soon returns; 4) generalized convulsions are accompanied by impaired consciousness, but after the convulsions stop, consciousness soon returns; 4) generalized convulsions are accompanied by impaired consciousness, but after the convulsions stop, consciousness soon returns. 4) In a one-time febrile illness, there is usually only one seizure, and rarely more than two; 5) The duration of convulsions is very short, from a few seconds to a few minutes, usually not more than 5-10 minutes; 6) There are no positive signs in the neurological examination, and no abnormal findings in the cerebrospinal fluid examination, except for increased pressure; 7) Electroencephalography is performed 1 to 2 weeks after the seizure. -8) The previous history of febrile convulsions and family genetic history can be followed up; 9) The prognosis is mostly good, usually no sequelae remain, and a few (1-3%) may be transformed into epilepsy. Any baby with febrile convulsions, age of onset, degree of fever, duration of convulsive seizures, and form of convulsive seizures do not have the characteristics of simple type of febrile convulsions can be considered as complex febrile convulsions. The age of first onset of complex febrile convulsions is mostly less than 6 months or more than 6 years. The duration of generalized convulsions is mostly more than 15 minutes, and convulsions may also occur during hypothermia. The form of seizures can be partial or generalized, with more than 1 convulsive episode during the same illness (or within 24 hours), and there may be abnormal neurological signs such as temporary paralysis syndrome after the convulsive episode. The prognosis is worse than simple febrile convulsions, especially if the baby has a family history of wires or organic brain lesions before the first febrile convulsions, which are more likely to develop into epilepsy. When the baby convulsions come, parents should do? 1, if the baby is home convulsions: it is recommended to make the baby lie on his side, untie the collar to prevent the collar is too tight to block the airway, clear the mouth, nose, throat secretions and vomit to prevent convulsions when inhaled airway leading to asphyxiation, keep the airway open. Place dental pads on the upper and lower molars to prevent tongue bite. Administer oxygen in severe cases. If the convulsion occurs in the hospital, the preferred drug to control the convulsion is Valium, followed by phenobarbital that, chloral hydrate, so parents should immediately inform the doctor if they find the baby convulsions in the hospital and give anti-convulsant medication. 2. Place a gauze wrapped chopstick or wooden spoon between the child’s upper and lower incisors to avoid the baby biting his tongue during the convulsion. 3. If there is fever and the body temperature is >38.5℃, oral antipyretics should be given as soon as possible or physical cooling methods such as ice caps on the head; 4. Closely observe the baby’s body temperature, breathing, heart rate, blood pressure, skin color, pupil size and urine volume. It is best to record them on paper to avoid forgetting them and to provide real and effective data to the doctor about the baby’s condition. 5.Send to the hospital as soon as possible to identify the cause of the convulsion and treat it promptly.
