If the baby’s body temperature is 38.5℃, it needs to be relieved by physical cooling and oral antipyretic to avoid the uncomfortable symptoms caused by the continuous rise of temperature. Physical cooling methods include warm water bath, applying antipyretic patches and soaking in baths, and at the same time, reduce the baby’s wearing of covered clothing, which is conducive to the dissipation of heat from the body and lowering of the body surface temperature. At the same time, you can lower the environmental temperature and encourage the baby to drink more water to promote the body’s metabolism, which is also conducive to cooling treatment. If physical cooling is not effective, oral ibuprofen or acetaminophen is needed to deal with fever-reducing drugs. If the baby is accompanied by drowsiness, poor mental response and shaking of limbs during fever, timely medical treatment is needed to avoid the symptoms of febrile convulsions.
