What Is a Fever Seizure?

Fever convulsions mainly refer to infants from 6 months to 3 years old who are infected with acute infections, especially viral upper respiratory infections, resulting in increased infant neurological metabolism, increased oxygen consumption, and accelerated personal blood flow. The nervous system is in an over-excited state, and infants and young children have hypothalamic hypoplasia and cannot tolerate this strong excitement. Therefore, infants and young children will have tonicity, clonic tics of facial muscles and limbs, and accompanied by infants and young children. Eye movements or unconsciousness. If left untreated, high fever and convulsions will occur repeatedly, which seriously affects the development of brain tissues in infants and young children, leading to a decline in children's intelligence .

Causes of high fever convulsions

The causes of convulsions in children can be divided into two categories: according to the presence or absence of infection, they are divided into infectious (fever convulsions) and non-infectious (non-fever convulsions). According to the affected part, it can be divided into two types: intracranial and extracranial.

(A) infectious convulsions (fever convulsions)

1. Intracranial diseases Viral infections such as viral encephalitis and Japanese encephalitis. Bacterial infections such as purulent meningitis, tuberculous meningitis, brain abscesses, and sinus thrombosis. Mold infections such as new cryptococcus meningitis. Parasitic infections such as cerebral cysticercosis, cerebral malaria, cerebral schistosomiasis, cerebral pulmonary fluke disease, and toxoplasmosis.

2. Extracranial diseases: febrile convulsions, toxic encephalopathy (severe pneumonia, pertussis, toxic dysentery, sepsis as the primary disease), tetanus, etc.

(2) Non-infectious convulsions (no fever convulsions)

1. Intracranial diseases Head injury such as birth injury, traumatic brain injury, neonatal asphyxia, intracranial hemorrhage. Brain development abnormalities such as congenital hydrocephalus, cerebrovascular malformations, large (small) head deformities, cerebral palsy and neurocutaneous syndrome. Intracranial space-occupying diseases such as brain tumors and brain cysts. Epilepsy syndromes such as major attacks, infantile spasms. Brain degenerative diseases such as demyelinating encephalopathy, cerebral macular degeneration.

2. Extracranial diseases Metabolic diseases such as hypocalcemia, hypoglycemia, hypomagnesemia, hyponatremia, hypernatremia, vitamin B1 or B6 deficiency and so on. Genetic metabolic diseases such as glycogen accumulation disease, galactosemia, phenylketonuria, hepatolenticular degeneration, mucopolysaccharidosis. Systemic diseases such as hypertensive encephalopathy, uremia, heart rhythm disorders, severe anemia, food or drug and pesticide poisoning, etc.

Convulsions in children, commonly known as convulsions, are one of the most common emergencies in children. Mainly show that the whole or local muscles have contractions that they cannot control, and they can also have conscious disturbances. There are many reasons for convulsions in children. More common are infections caused by bacteria and viruses, such as pneumonia, whooping cough, typhoid, and dysentery. In addition to convulsions caused by poisoning in children, these diseases also cause convulsions due to high fever, called fever convulsions. This kind of convulsions usually occur when the fever is short, the convulsions cease to be awake, and rarely more than two convulsions in a fever. The fever convulsions stopped. However, recurrent episodes can occur and a seizure can occur as soon as a fever develops. This type of convulsions mostly occurs in children under the age of six. In addition, intracranial infections such as encephalitis, meningitis, brain abscesses, and parasitic diseases in the brain, in addition to fever can cause convulsions, because the lesions occur in the brain, stimulation of relevant parts of the brain can also cause seizures. Non-fever diseases such as tetanus, epilepsy, brain trauma, brain tumors, hypocalcemia, hypoglycemia, and rickets caused by vitamin D deficiency can also cause convulsions.

Fever convulsions are a common medical condition. About 3% of infants between 6 months and 6 years of age have a convulsions when they have a fever or a high temperature.

(Note: Doctors also mentioned that febrile convulsions are a genetic inheritance that Niu Niu had as a child.)

High fever convulsions

When normal brain activity is disturbed, high-temperature convulsions can occur. High fever often occurs without warning. During a febrile seizure, your child may react as follows:

The body becomes stiff or weak

· Unconscious or unable to recognize the surrounding environment

· Body twitching

·Difficulty breathing

High fever convulsive treatment principles

(1) Emergency treatment for children with seizures: When the child has a high fever convulsion, first place the child flat and keep the child in a prone position. Because the child has a fever and convulsions, the symptoms of nausea and vomiting will occur before the coma. Eliminate foreign bodies or vomit in the child's nasal cavity and mouth. The child's jaw is raised slightly, the collar of the child is quickly untied, and the surrounding air is maintained to prevent the child from breathing difficulties. Let the child bite the chopsticks or press the tongue to prevent the child from biting the wound tongue due to upper and lower molars during convulsions and convulsions. Acupoints that can be properly stimulated in people, Hegu, Neiguan. Parents need to remain calm and be admitted to the hospital as soon as possible.

(2) Admission treatment: After the child is admitted, the medical staff should keep the surrounding rescue environment quiet, and carefully ask the child's history of the illness, the maximum temperature of the fever before the seizure, the duration of the high temperature, and whether the child has a rash and whether The occurrence of vomiting, the way of vomiting, the appearance of the vomit, the change of urine and urine, and strive to be comprehensive and detailed. Measure the temperature, pulse, respiration, and blood pressure of the child, observe the condition of the child's condition and convulsions, and actively improve the blood routine, urine routine, stool routine, sputum culture and other tests to find the cause of the febrile convulsions, and give Dialectical treatment.

(3) Rescue before the cause is unknown: children with febrile convulsions often accompanied by long periods of high fever, fewer urination times, yellow discoloration, and some children can be clearly observed that the dryness of the lips and tongue is less, and this should be given to patients Infusion treatment of children, timely replacement of body fluids for children, correction of water and electrolyte disorders in children, to prevent the child's convulsions from getting worse; at the same time, children should be fixed on the limbs of the bed, should not be forced too hard, to prevent children from convulsions due to limb rigidity Sprain fracture or unconscious fall; Diazepam may be given 0.1 to 0.3 mg / kg or phenobarbital sodium 5 to 8 mg / kg intramuscularly to relieve respiratory distress caused by respiratory muscle spasm in children. Oxygen inhalation can also be given to children suffering from respiratory distress. Because children have fever and convulsions, the oxygen demand of children's brain cells and tissue cells will increase. Providing active oxygen inhalation to children can increase blood saturation in children. Degree, so as to ease the performance of convulsions in children; 5% chloral hydrate 1.0-1.2ml / kg retention enema can be given to control seizures; use a towel moistened with water or alcohol on the forehead of the child, or more Apply rubbing to the palms, toes, and fronts of the children to help them dissipate heat. In the winter, while helping the children to have fever, parents and medical staff should do a good job of keeping warm, and at the same time, change the wet clothes of the children as soon as possible to prevent the children from catching a cold, thereby further aggravating the illness.

(4) Diagnosis and treatment of children's sobriety: After the child is awake, the child's wet clothes should be replaced in time to check whether the children's limbs, skin, bones and other structures are damaged during the seizures. Injury should be promptly disinfected, if the child's bone damage should be promptly reset. Inspect the mouth of the child carefully to observe whether bites or aphthous ulcers have occurred. For those who have bites or aphthous ulcers, gargle with normal saline. The child should eat some high-calorie, high-protein, digestible, easy-to-absorb foods after being awake, and avoid fatty and thick and spicy things. Observe the clinical recovery of children, summarize the emergency treatment methods and experience of children with febrile convulsions.

High fever and convulsions

Children with high fever and convulsions may stop without any medical measures. If the seizure does not stop within 5 minutes, the child should be referred to a doctor promptly. Although high fever is often caused by a viral infection, doctors still need to check the child and sometimes blood tests to find out the true cause of the high fever.

High fever and convulsions

High fever and convulsions recur. As children get older, the chance of a second seizure decreases year by year. Children over 6 years of age are less likely to develop a high-temperature convulsion.
