What are the causes and symptoms of febrile convulsion?

summary

Febrile convulsion refers to the convulsion of children in the early stage of respiratory tract infection or other infectious diseases when their body temperature is higher than 39 ℃, excluding intracranial infection and other organic or metabolic diseases leading to convulsion.

What are the causes and symptoms of febrile convulsion?

The main manifestations were sudden tonic or clonic twitch of the whole body or local muscles, binocular gaze, strabismus, straightening or upturning, and loss of consciousness. Febrile convulsion can be divided into simple febrile convulsion and complex febrile convulsion.

All ages (except neonatal period) can occur in children, most of them are from 6 months to 4 years old. Simple febrile convulsion is better, but complex febrile convulsion is worse. Febrile convulsion febrile convulsion is a kind of convulsion phenomenon associated with fever (body temperature up to 39 ℃). At the same time, it will also be accompanied by fever and infection of other parts of the body outside the brain. It often occurs in children aged 6 months to 5 years. Although the symptoms of convulsions are terrible, they are usually not serious.

The etiology of febrile convulsion is still unclear. The study found that the disease has obvious heredity, may be autosomal dominant inheritance, with age-related incomplete exodominance and expression. According to the characteristics of the onset age, it is estimated that the exotropism of the disease began to appear in about 6 months, and was most obvious at 1.5-2 years old, then gradually decreased, and then decreased to the low point after 4 years old. The convulsion tendency determined by heredity is expressed in a certain age stage, which is induced by fever caused by infection, that is, clinical febrile convulsion. According to traditional Chinese medicine, the external cause of the disease is exogenous pathogenic factors, while the internal cause of the disease is timidity and plain accumulation of liver heat.

matters needing attention

Children who have suffered from febrile convulsions should be given oral antipyretic (such as aspirin) and sedative (such as lumina) in advance when they have a cold or febrile disease, or physical cooling should be used to prevent sudden rise of body temperature.
