Introduction
In general, intravenous (IV) fluid administration can help manage high fever, but it should be performed under a doctor's supervision. IV fluid therapy is only one method for controlling high fever; treating the underlying cause is even more important. Therefore, while using IV fluids, it is also necessary to combine other treatment measures, such as anti-infective or antiviral therapies. During the recovery period, adequate rest, increased water intake, and proper hydration are essential.
Generally, intravenous (IV) infusion can help control high fever, but it must be performed under the guidance of a doctor. Detailed explanation is as follows:
When high fever is caused by dehydration, electrolyte imbalance, or other conditions requiring rapid replenishment of fluids and nutrients, IV infusion can quickly correct the body's fluid and electrolyte balance, thereby indirectly helping to control the fever. Through IV infusion, medications can directly enter the circulatory system, avoiding potential absorption barriers associated with oral administration and enhancing drug effectiveness. For patients requiring antipyretic and analgesic drugs due to high fever, IV infusion can deliver the medication directly into the bloodstream, thereby rapidly reducing body temperature.
IV infusion is only one method for controlling high fever; more importantly, treatment should target the underlying cause. Therefore, while administering IV infusion, other treatment measures such as anti-infective or antiviral therapies should also be employed. During the recovery period, adequate rest, increased water intake, replenishment of body fluids, and prevention of dehydration are necessary.
