Infants with a temperature of 37.4 degrees can usually be cooled down physically as follows. If an infant’s temperature is 37.4° by axillary temperature measurement, it is considered to be high, and the child can be kept under observation for a period of time by drinking more water and urinating more. Physical cooling methods can also be taken, such as applying antipyretic patches to the child, or using warm wet towels to wipe the child’s palms, armpits, feet, groin, neck and other areas rich in large blood vessels, through repeated wiping can generally lower the temperature. In addition, it is also necessary to closely observe the child’s mental status and temperature fluctuation range, if found that the child’s body temperature has risen, should be brought to the hospital in a timely manner. If necessary, you can follow the doctor’s advice to use drugs to lower the temperature. In conclusion, if the child has a persistent temperature rise, it is necessary to consult a doctor in time, and because of the risk of using drugs for infants, please follow the doctor’s advice if you need to use them.
