In European and American countries, patients are not advised to take injections or intravenous drip until they are seriously ill or in emergency rescue. Only when the body temperature exceeds 38.5℃, high fever persists or severe water shortage is considered.
Even for infusion, American hospitals have strict operating procedures, such as thoroughly sterilizing equipment and using disposable needles. There is even no "antipyretic needle", and non-drug therapy is generally advocated, such as rest and strengthening nutrition. Many Americans were quite surprised to learn that China people often need infusion when they have a cold and fever, because when they are ill, doctors just say to rest more and drink more water.
Generally, when the patient's body temperature is below 38.5℃, he takes medicine or uses ice packs to physically reduce fever. When the body temperature exceeds 38.5℃ and the high fever persists or the patient is seriously dehydrated, which leads to the disorder of body fluids and electrolytes, intravenous drip fever is the last choice.
