Febrile convulsions are caused by a sudden increase in body temperature and can be accompanied by other symptoms of infection other than brain. It occurs in children aged 5-6 years and is most likely to develop at the age of 2 years. The main mechanism of the disease is the change in nerve cell metabolism, oxygen consumption and blood flow when the child is feverish, as well as the overexcitation of the central nervous system at this age. As the thalamus of the child’s brain tissue is not mature, it generates strong discharges that are transmitted to other parts of the brain, causing convulsive episodes, which have obvious family genetic characteristics. The symptoms of convulsions are terrible, but usually not serious. After the onset of convulsions, you need to seek medical attention promptly. Place the child on the floor away from hard objects and sharp objects, with the head tilted to the side to facilitate the discharge of secretions from the mouth and prevent choking and coughing. Reduce the child’s fever promptly by physically wiping the child with a warm towel to reduce the temperature. Seek medical attention at the hospital as soon as possible.
