What is an IV infusion?

An IV infusion refers to the long-term administration of medication directly into a patient's bloodstream via an intravenous (IV) line. This method is particularly beneficial for delivering medications, fluids, or nutrients in a controlled and sustained manner over an extended period, which is essential for patients who may require consistent and gradual infusion of therapeutic agents.

In this context, long-term administration allows for effective management of various medical conditions, as it ensures that the required drug levels in the bloodstream can be maintained without the need for frequent injections or doses. It is often used in treatments such as chemotherapy, hydration therapy, or antibiotic administration, where a steady concentration of medication is critical for efficacy.

The other methods mentioned do not capture the primary characteristic of IV infusions. Administering medication through a needle typically refers to single injections rather than a continuous or prolonged delivery method. The concept of rapid delivery indicates a quick administration, which contrasts with the prolonged nature of an infusion. Direct injection into the muscle implies intramuscular delivery rather than intravenously, further distinguishing the method of IV infusion.
