An IV catheter is a thin, flexible tube placed into a vein. IV stands for intravenous, meaning inside a vein. It can be used to give fluids, medicines, blood products, or nutrition, and in some cases to draw blood. Once placed, the needle is removed and the soft catheter stays in the vein.

Fluid or medicine then flows into the bloodstream through the line. The site is covered with a dressing to hold the catheter in place and reduce contamination.
A peripheral IV catheter is short and placed in a smaller vein, often for short-term treatment. A central venous catheter is longer and reaches a larger central vein for treatments that need stronger vein access. Midline catheters are longer than peripheral IVs but do not reach the central veins. The type depends on the treatment, expected duration, vein condition, and medicine being given.
An IV catheter can be used for hydration, antibiotics, pain medicine, anesthesia, chemotherapy, contrast dye, blood transfusion, or emergency treatment. It can also be used when a person cannot take fluids or medicine by mouth. Some IV lines are placed for a single visit, while others stay in place for longer care. The care team chooses the line type based on safety, comfort, and treatment needs.
The IV site should be checked for pain, redness, swelling, leaking, warmth, bleeding, or dressing problems. These signs can point to irritation, infection, infiltration, or phlebitis. Keep the dressing clean and dry unless staff give different instructions. Tell the care team right away if the site hurts, the pump alarms, or fluid stops flowing.
No. The needle helps place the catheter, then it is removed. The soft plastic catheter stays in the vein.
Yes, but movement can be limited depending on the IV location and treatment. Avoid pulling, bending the line sharply, or getting the dressing wet.
Timing depends on the catheter type, site condition, treatment plan, and facility policy. Staff will remove or replace it if it stops working or shows signs of irritation or infection.
Tell the nurse or care team right away. Swelling can mean fluid is leaking into nearby tissue or the vein is irritated.
