Every baby experiences fever, because children have poor resistance immunity and are prone to fever symptoms. If it is a low fever, the situation can return to normal through its own immune regulation and physical cooling, etc., without major effects. However, if it is as high as 39.7 degrees, it is a high fever and it is recommended to take antipyretic to first and go to the hospital for appropriate treatment. If high fever persists, danger such as convulsions can occur and affect the brain in severe cases. In case of high fever convulsions, it is recommended not to shake the child and not to pat the child. It is important to follow the following actions to prevent further damage from occurring 1. Keep the child lying flat with its head tilted to one side to avoid oral saliva and vomit entering the trachea causing asphyxia or aspiration pneumonia. At the same time, the child’s head is tilted to the side to avoid oral saliva and vomit from entering the trachea and causing asphyxia or aspiration pneumonia. Also untie the child’s collar to avoid the neck being strangled too tightly to affect the smooth flow of the airway. 2, prevent the child from biting the tongue, in order to prevent the baby from biting the tongue, you can twist the handkerchief or thin clothing into a twist to stuff in the middle of the child’s incisors. 3, after the child’s convulsions stop, parents should immediately send to the nearest hospital, in order to check the cause and further treatment. 4.When the baby has a spasm, let him lie flat on his back to ensure that he does not suffer secondary injuries. Later, let the child lie on his side so that he can breathe smoothly and prevent saliva or vomit from blocking the airway. Do not try to break the child’s mouth open. A child who has spasms due to fever or some other reason is not in danger of biting his own tongue.
