Febrile convulsions, also known as hyperthermia, are the most common convulsive disorder in pediatrics and usually develop with a fever of 38.5°C or higher. Essentially febrile convulsions is a genetic disorder and is an inherited form of epilepsy. It is just that it is very common, and most people end up well, do not affect their intelligence, do not affect their future schooling or work, and are actually not that scary. In general, people think of epilepsy as an “incurable disease” that is very scary, so they do not want to associate febrile convulsions with epilepsy. About 60% of people with febrile convulsions have only one seizure in their lifetime and no more recurrences, while 40% of people have recurrences, even without fever and convulsions, and may have seizures of a type they did not have before, some with dozens of recurrences, and a few affecting their intelligence. How to prevent recurrence in cases where there is already a recurrence? At present, there are two main methods. One is temporary medication prevention, and the other is long-term medication prevention. The so-called temporary medication prevention is to take the drug diazepam (Valium) to prevent convulsions immediately when there is a fever, and take it for several days until the body temperature has normalized and there is no more fever. However, there are times when this method does not work. Often, parents do not know that their child is febrile until the convulsions are detected, and only when the temperature is taken when the convulsions are detected do they know that the child is febrile, which means that these children have convulsions as soon as the fever starts. Sometimes the child is not under the supervision of someone experienced in febrile convulsions, so temporary preventive medicine often does not work. For patients with a history of recurrent febrile convulsions, it is important to take long-term medication for prevention. Long-term medication prevention refers to long-term, regular medication, commonly used drugs are valproic acid or phenobarbital. This method many parents can not accept, worrying that long-term medication will have side effects, will affect the child’s intelligence. In fact, most children are safe to take medication, and the very few children who have adverse reactions will turn out to be safe under the close supervision and guidance of a specialist. In fact, it is the recurrence of febrile convulsions in children that causes great psychological and physical trauma to the family and the child. The current methods and drugs for preventing febrile convulsions are relatively mature, but there is a gap in the degree of parental cooperation, so that some children have recurrent relapses. It is undeniable that even if we strictly follow the current program of long-term medication, there are still a small number of children with poor prevention of febrile convulsions and recurrent relapses, which is our goal to overcome in the future.
