Infant fever syndrome is also known as muffling syndrome. It is mainly caused by the baby being overly warmed or smothered by the family. Infantile fever syndrome is most common in babies under the age of 1 year, and is especially common in newborns who are not yet full term. What is infantile fever syndrome? Infantile fever syndrome is also known as muffled fever syndrome. It is mainly caused by the baby being overly warmed or smothered by the family. Infantile fever syndrome is most common in babies under 1 year of age, and is especially common in newborns who are not yet full term. As the weather starts to cool down, especially in the morning and evening, mothers worry about their little ones catching a cold, and always unconsciously wrap their babies in two layers of blankets, resulting in many cases of infant muffled fever syndrome. What causes babies to get sick? Small babies have a relatively small body surface area than adults, and heat dissipation is slower than adults, so if they are covered for too long or kept too warm, the temperature around the baby’s body will rise sharply, and the heat is wrapped in clothes or quilts and cannot be dissipated, resulting in the baby’s body in a state of hyperthermia. The baby is in a state of hyperthermia, the small blood vessels on the human skin will appear compensatory expansion, to sweat or whistle faster to accelerate heat dissipation, resulting in the baby sweating a lot, serious cases will cause dehydration and electrolyte disorders, and even circulatory failure. If resuscitation is not timely, shock or even death can occur quickly. Those who survive may also suffer from severe sequelae of brain injury such as mental retardation, motor impairment, dumbness, deafness and epilepsy. How does the baby behave? After a baby has been covered with fever for a long time, his or her body temperature will rise rapidly and he or she will sweat profusely and soak through the clothes. In addition, the baby may become irritable, urinate less, and have a sunken fontanel and eye sockets. If the central nervous system is involved, frequent vomiting, screaming, unresponsiveness or coma may occur. How is infantile fever syndrome treated? Cooling and reducing fever is the basic treatment for infant fever syndrome. The mother must first evacuate the baby from the hot environment, let the baby get fresh air as soon as possible, and take the baby to the doctor as soon as possible. For babies with infantile fever syndrome, doctors will treat them with fluid therapy, i.e. hydrate them actively and correct acidosis. How to avoid infant fever syndrome? Mothers should add and remove clothes for their babies according to the change of weather, and should not cover their babies too tightly, otherwise it is not conducive to heat dissipation. As long as the baby’s feet are warm, it means that the clothing and blankets are of appropriate thickness and there is no need to add more.
