When a one-year-old baby has a fever of 39 degrees Celsius, you should not be careless and give the child antipyretic and analgesic drugs immediately to reduce the child’s fever, which must be reduced to below 38.5 degrees Celsius, otherwise the child is prone to febrile convulsions, which can produce irreversible damage to the child’s brain cells, and can take ibuprofen suspension orally. If there is repeated fever or persistent fever, you can usually repeat the medication once after an interval of 4-6 hours, but not more than 4 times a day within 24 hours, and the specific dose should be taken according to the child’s weight and in accordance with the instructions. Physical cooling can prolong the effect of antipyretic drugs and enhance the efficacy of antipyretic drugs, and can be combined with physical cooling.
