Febrile convulsions are more common critical illnesses in pediatric patients and occur when the body temperature is above 38°C due to an infection outside the central nervous system. Most of them are caused by a sudden rise in body temperature that exceeds the range of the child’s brain thermoregulatory center. About 2% to 5% of children under 5 years of age have had febrile convulsions. The first onset is most often seen between 6 months and 3 years of age, with very few onset below 6 months and above 6 years of age. The baby often has a fever first, followed by convulsions, which appear mostly within 12 hours after the start of the fever, and when the body temperature rises suddenly, there is a brief generalized convulsive seizure, during which the child suddenly loses consciousness, both eyes stare, squint or turn upward, the head is tilted back, the muscles of the face and limbs twitch, the hands are held very tightly usually lasts for several minutes, and most of them only have one seizure per fever, and the consciousness is soon after the seizure The severity of sober convulsions is not proportional to the body temperature, the convulsions last from a few seconds to a few minutes, more than 10 minutes, and after the seizure, the consciousness is clear. It is important to prevent seizures because they are scary and can affect brain function and may cause epilepsy if they occur frequently. Prevention of febrile convulsions should be noted as follows: 1. Improve immunity: strengthen nutrition, regular outdoor activities to enhance physical fitness and improve resistance. If necessary, use some drugs to improve the immune function under the guidance of a doctor. 2, prevention of colds: when the weather changes, add and remove clothes at the right time to avoid getting cold; try not to go to public places, places with a large number of mobile people, such as supermarkets, stations, cinemas, etc., so as not to be infected with colds; if adults at home have colds, they need to wear masks and have as little contact with children as possible; open windows from time to time every day to keep the air circulating at home. 3, active antipyretic is very important: once a child with high fever convulsions in the cold, parents should closely observe its temperature changes, once the temperature reaches 38 ℃ or more, should be actively antipyretic. There are two ways to reduce fever, one is physical antipyretic; the second is drug antipyretic. Drug antipyretic is very important, do not wait until the child’s body temperature rises very high to put to use, in the body temperature of 38 ℃ when the drug is used. Then go to the hospital, do not hold the child to the hospital without doing any antipyretic treatment, it is easy to have a convulsion on the way to the hospital. 4, the correct application of anticonvulsant drugs: (1) intermittent use of anticonvulsant drugs: that is, usually do not use drugs, only at the beginning of each febrile illness, when the body temperature rises to 37.5 ℃, immediately rectal injection of Valium solution or give oral Valium, also available Valium suppositories; (2) long-term use of anticonvulsant drugs: more than five episodes of febrile convulsions per year, each episode of febrile convulsions lasting more than (2) long-term anticonvulsant drugs: for children with more than 5 episodes of febrile convulsions per year and each febrile convulsion lasting more than 30 minutes, long-term anticonvulsant drugs can be taken, and the commonly used drug luminal should generally be taken orally for six months. Also pay attention to adverse drug reactions. After the first febrile seizure, 30% to 40% of children may have another seizure. 75% of children have another seizure within 1 year after the first seizure and 90% within 2 years. Therefore, the mother should have all the first aid items and medicines at home, such as thermometer, tongue depressor, antipyretic, antispasmodic, etc.; if the child has fever, the temperature should be measured in time, and the temperature should be cooled by medication at about 38℃; phenobarbital is a long-acting sedative-hypnotic drug, and for children with a history of febrile convulsions, the anticonvulsant should be used in the early stage of fever, and the body temperature should be increased to high fever. The anticonvulsants have already reached the effective concentration to suppress convulsions, which can inhibit convulsions and effectively prevent the recurrence of febrile convulsions in children. Because febrile convulsions are prone to recurrence, parents should not overdress their children every time they have a fever, cover them too thickly, that is, do not “cover their children”. The physical method or medication is actively used to reduce fever, even if the body temperature is not high, you should also take antipyretic drugs in time.
