Physical cooling is the preferred way for many parents to cool their babies, but inappropriate physical cooling can easily lead to vasoconstriction of the child, which is harmful to the condition. The premise of physical cooling in the hospital must be that the child’s temperature cannot be effectively lowered even after taking medication, and that physical cooling will only be carried out under supervision if the fever continues for fear of causing bodily harm. Many parents will use alcohol to cool their babies, which has great potential risks. Baby cooling with alcohol may have 4 kinds of sequelae 1, allergic to alcohol If the baby is allergic to alcohol, it is not visible at birth, but if the use of alcohol to cool down, there will be immediate adverse reactions, such as skin rashes, red spots, etc. 2, may cause alcohol poisoning in babies Alcohol is volatile, and when wiping on the baby’s skin, it is likely that alcohol will enter the baby’s body through the skin and respiratory tract, causing alcohol poisoning or coma. 3. Cooling is useless, high fever repeatedly Alcohol works too quickly and can have the opposite effect. The baby may start to tremble all over and cause the body temperature to rise again. 4.Alcohol causes excitement and affects the baby’s heart rate. Alcohol itself can bring excitement, and babies are more sensitive than adults, which can cause a reflexive slowing of the heart rate and even cause ventricular fibrillation and conduction block, leading to cardiac arrest.
