In pediatric fever, when the body temperature is between 37.5℃-38℃ is low fever; 38℃-39℃ is medium fever; over 39℃ is high fever; over 41℃ is super high fever. At this time, parents should closely monitor the fluctuation of the child’s body temperature. When the body temperature is below 38.5℃ and the mental state is still good, don’t rush to use antipyretic drugs first, but adopt appropriate physical cooling methods, the principle of which is to wipe with warm water to make the child’s body surface heat dissipate, but because only the surface heat can be dispersed, it needs to be done continuously. It is also the safest because it is a physical method with no side effects. The correct physical cooling method is: First: choose warm water. Second: Dip a towel in water and wring it out slightly. Third: Wipe on the baby’s body, focusing on the head and neck, limbs, armpits, groin and other areas where large blood vessels pass through, in order to dissipate heat and cool down. Fourth: continuous wiping, and with the temperature measurement, until the child’s body temperature down. Fifth: Dress less and cover less. Wear less clothes and cover less to let your baby dissipate heat naturally. It is not recommended to use white wine or alcohol to wipe your baby’s body. It is true that alcohol can cool the skin when it evaporates, but it is because the alcohol works too quickly and is counterproductive. In addition, alcohol can also be inhaled through the skin and breathing into the baby’s body, causing alcohol poisoning, which can be life-threatening in serious cases. In addition, you should also give your child plenty of water or breast milk. Baby fever is a body consumption of water process, it is estimated that for every 1 ℃ increase in body temperature, to evaporate 10% of the body’s water. In addition, drinking more water can speed up sweating and urination, promoting the discharge of toxins and metabolic wastes from the body, facilitating the recovery of the affected child as soon as possible. Therefore, you should feed warm water several times or give oral rehydration salts in appropriate amounts to make the body sweat or urinate to help cool down and avoid dehydration. Bottled fruit juices and milk with high sugar content and high osmotic pressure will increase the gastrointestinal burden of the child and are not recommended. If your child’s temperature does not drop through the above methods, you should seek medical attention once the temperature exceeds 38.5℃.
