A central line is a type of catheter that is placed in a large vein that allows multiple IV fluids to be given and blood to be drawn. When compared to a typical IV line

, a central line is larger, can stay in place longer, can deliver a greater volume of fluids, and allows blood to be drawn easily.

Why would a central line be placed?

Why is it necessary? A central line is necessary when you need drugs given through your veins over a long period of time, or when you need kidney dialysis. In these cases, a central line is easier and less painful than having needles put in your veins each time you need therapy.

What are the indications for the placement of a central line?

Some indications for central venous line placement include fluid resuscitation, blood transfusion, drug infusion, central venous pressure monitoring, pulmonary artery catheterization, emergency venous access for patients in which peripheral access cannot be obtained, and transvenous pacing wire placement.
