Intravenous therapy, often abbreviated as IV therapy, is a medical treatment that delivers fluids, medications, or nutrients directly into a patient's bloodstream through a vein. This method allows for rapid absorption and is commonly used in hospitals for patients who are unable to take medications orally or need immediate hydration and support. The process involves inserting a thin tube, called a catheter, into a vein, usually in the arm or hand. IV therapy can be used for various purposes, including rehydration, administering antibiotics, or providing chemotherapy. It is a vital tool in modern medicine for managing a wide range of health conditions.
