Relapse prevention (1) Intermittent short-course dosing: No medication is usually administered, and once fever is present, diazepam 0.6-0.8 mg/(kg?d) is administered rectally or orally immediately, with a loading dose of 0.5 mg/kg for the first dose, and is maintained until temperature stabilizes and returns to normal. Indications: (1) History of prolonged seizures of 15-20 minutes or more; (2) Risk factors for epilepsy; (3) History of 2 or more febrile seizures. (2) Long-term continuous preventive medication: i.e., daily antiepileptic drugs to reduce febrile convulsion recurrence and convulsive brain injury, commonly used effective drugs are sodium valproate, phenobarbital and topiramate. Indications: (1) a history of 2 or more episodes of low-grade fever (<3 8°C); (2) a history of long-range seizures lasting more than 1 5 to 2 0 minutes or in children with epilepsy risk factors for whom intermittent short-range medication is ineffective or difficult to implement (e.g., the interval between fever and convulsions is too short); (3) a history of 4 or more febrile convulsions. The course of treatment: generally 2 years, i.e., continuous medication until no more convulsive seizures for more than 2 years, and then slowly reduce the amount of medication to stop.
