What are febrile convulsions? Febrile convulsions are diagnosed when the first attack occurs between 3 months and 5 years of age and the body temperature is above 38. FS can be diagnosed when intracranial infections and other organic and metabolic diseases causing convulsions are excluded and there is no previous history of febrile convulsions. FS commonly develops between 6 months and 3 years of age, with a peak age of 9-20 months after birth, and 3-7% can develop by 7 years of age. Classification of febrile convulsions: divided into simple febrile convulsions and complex febrile convulsions Simple febrile convulsions: often full-blown seizures, lasting less than 10 minutes, with no recurrence within 24 hours or during a febrile event Complex febrile convulsions: focal manifestations, lasting more than 10 minutes, with recurrent febrile convulsion persistence (seizures lasting more than 30 minutes) occurring in 5% of cases within 24 hours. Risk factors for recurrent FS are: 1. family history of FS; 2. age <18 months at first FS; 3. hypothermia at the time of convulsions; 4. early onset of convulsions with fever. Treatment of FS seizures: Most FS are of short duration and resolve themselves quickly within 10 min without the need for anti-convulsive drugs, and most convulsions do not recur as long as they are promptly treated with oral or injectable antipyretics and the primary cause. For those who have frequent or prolonged convulsions, emergency treatment measures should be taken. The first step is to use a fast and effective drug, diazepam is currently preferred, and diazepam solution can be given as an enema at home. Treatment to prevent recurrence of FS: (1) intermittent application of diazepam during fever; (2) long-term oral anti-seizure medication phenobarbital or sodium valproate. Oral antipyretics alone are not effective in preventing recurrence of FS.
