"intravenous therapy"的定义和意义

What is "intravenous therapy"?

Intravenous therapy, also known as IV therapy, is a medical treatment where fluids, medications, or nutrients are delivered directly into a vein through a needle or a thin tube. This method allows for quick absorption into the bloodstream, making it effective for providing hydration, giving medications to treat infections or pain, or delivering nutrients for patients who cannot consume food or liquids orally. IV therapy is commonly used in hospitals, clinics, and sometimes at home under medical supervision to treat various conditions and support overall health.
