intravenous
Meaning: Administered directly into a vein, typically via a needle or cannula. Commonly abbreviated to IV in clinical settings.
Intravenous administration allows rapid delivery of fluids, medications, blood products, and nutrition directly into the bloodstream, bypassing the digestive system. It is the fastest route for drug delivery and is essential in emergency medicine, surgery, and intensive care. In British hospitals, a cannula (thin plastic tube) is usually inserted into a vein in the hand or arm. The term functions both as an adjective ('intravenous fluids') and, informally, as a noun ('she's on an intravenous'). It collocates with 'drip,' 'fluids,' 'infusion,' 'access,' and 'cannula.'
