Children are prone to convulsions when they have a fever because some babies have an underdeveloped nervous system and poor cortical inhibition, and when they are stimulated, they are prone to convulsions, which are medically known as convulsions. They mostly occur in children aged 6 months to 6 years. Some parents think that high fever convulsions will burn the baby’s brain, in fact, a high fever convulsion does not have a big impact on the child, and will not hurt the brain leaving sequelae, parents do not have to panic too much, the longer the duration of the convulsion, the more episodes, the greater the possibility of causing hypoxic brain damage, the more likely to affect intelligence, so when the convulsions, should try to stop immediately. When a convulsion occurs, the baby is confused, and if the vomit in the mouth is mistakenly inhaled into the trachea, it can cause the risk of asphyxiation, so it is necessary to promptly clean the vomit from the child’s mouth and keep the airway open. Immediately let the baby lie flat to ensure that it will not touch any hard, sharp objects, untie the collar of the blouse, wrap chopsticks with clean gauze or handkerchief and place them between the upper and lower molars to prevent biting the tongue, and if the baby’s teeth are tightly closed, do not forcefully insert them to avoid causing damage to the mouth, lips and teeth. In addition to physical cooling, cold towels can be placed on the baby’s forehead, palms and thigh roots to help lower the body temperature. Convulsions last from a few seconds to a few minutes and usually do not last more than ten minutes. If the convulsions do not stop or are frequent, you should go to the hospital immediately. If your baby has a history of febrile convulsions in the past, pay attention to the changes in your baby’s temperature, and when you find that your baby has a high fever, you should reduce the fever in a timely manner, either by physical cooling or by taking antipyretic drugs to avoid re-induced convulsions after a high fever, and antipyretic drugs should be used under the guidance of a doctor.
