The principle of fast fever reduction for children is that after applying antipyretic treatment, it is necessary to actively cooperate with physical cooling to accelerate blood circulation in the child’s body, which is conducive to fever reduction and faster fever reduction. In two aspects: 1, low fever, low fever state body temperature below 38.1 ℃, and greater than or equal to 37.4 ℃, you can not take oral antipyretic drugs, only to give physical cooling, you can give the child to drink more water, with warm water wipe, at the same time, large children can carry out physical activities, running, jumping can accelerate blood circulation, these exercises are as far as possible within an hour, so that the child’s temperature will recede. 2, high fever state in the oral antipyretic drugs, must actively cooperate with the above physical cooling methods at the same time, so that the fever is still faster. If the body temperature continues to rise and does not want to retreat, you can take the method of intramuscular injection or intravenous infusion in the hospital to quickly achieve the purpose of reducing fever.
