An intravenous (IV) infusion is delivery of fluid (such as saline or glucose) or other medication (such as chemotherapy drugs) from a plastic bag containing the fluid or medication through plastic tubing connected to a catheter that is attached to a needle, which enters a vein of a patient. The fluid or medication then travels in the bloodstream through the body to hydrate or treat the patient.
The process of IV infusion is a common method of administering IV chemotherapy drugs over a specified period of time (e.g., a particular number of hours).
