If the child has a high fever, the convulsion may be a simple convulsion, ie a generalized convulsion (eyes roll back, mouth foaming at the mouth, jerking limbs, lasting about 1-2 minutes). After the seizure, the baby returned to normal consciousness, all day fever that day there was only one convulsion. The child has no previous history of convulsions such as meningitis or brain injury, brain diseases; There is no family member with epilepsy or brain disease.

When a child has a high fever, because the brain cells cannot adapt to the sudden increase in temperature, it leads to abnormal electrolytes in and out of the cells, electrical discharge causing the child to have convulsions. But a mere convulsion is not dangerous. In the past, doctors used to give the baby a seizure prevention, but now, according to the latest guidelines of the world, there is no need to rush to prevent convulsion if the convulsion does not exceed 4 minutes.

If your child has a convulsion, immediately tilt your child to the side. Because when a child has a seizure, there may be increased salivation, the risk of choking if lying on his back. Parents should give their children fever-reducing medicine and suppositories, and watch the clock to know the time of convulsions. When a child has a seizure, parents are often worried, so they think the seizure is long, but sometimes only 1-2 minutes. At this time, parents must be very calm and should not put their hands in the baby’s mouth. In simple febrile convulsions, the tongue often retracts inward, but rarely sticks out; Usually after 1-2 minutes, the baby will return to normal.

Children with dengue fever have convulsions with high fever, we also advise not to use anticonvulsants in a hurry. Because studies around the world show that, some cases of febrile convulsions can turn into epilepsy (such as in febrile seizures up to 2-3 times, with a family history of epilepsy), most cases Children will heal on their own after 6 years of age. Taking anticonvulsants sometimes causes side effects.

When the baby has a high fever, parents need to cool down, always stay with the baby because they can convulse at any time. Parents should not give children water to drink bamboo leaves, pot leaves … but should take medicine to reduce fever. Antipyretics of the paracetamol group for children will not be a problem. You can give the child oral or rectal suppositories containing paracetamol, and aspirin is contraindicated in dengue fever.
