Stimulation of the brain after a rapid rise in body temperature can cause abnormal firing of motor neurons in the brain and febrile convulsions, mostly in the pediatric population. Febrile convulsions are mostly brief and self-limiting, and should be sent to the emergency room if they last more than 10 minutes. The general treatment is to keep the airway open, administer oxygen, monitor vital signs, and establish intravenous fluid access, in addition to symptomatic treatment, timely fever reduction and physical cooling, and to ensure adequate hydration. If the febrile convulsions are greater than 5 minutes, anti-convulsive treatment should be carried out, and generally Valium can be used for sedation or chloral hydrate enema. If the convulsions are not controlled or if there are repeated seizures, treat them as persistent status epilepticus. It is also important to pay attention to prevention, which is mainly for long-range febrile convulsions or febrile convulsions that occur repeatedly, and is usually prevented by oral administration of Valium tablets at the beginning of the fever. Or various bacterial or other microbial infections that lead to high body temperature causing limb convulsions, sedative drugs should be used first to terminate the convulsive episodes, and then active use of sensitive antibiotics to control the infection. At the same time, cooling drugs should be used to bring the body temperature back to normal level. In short, hyperthermic convulsions can be recovered as long as the cause is controlled and there is no need to worry too much.
