A central line, also known as a central venous catheter, is a catheter that is placed into a large vein, rather than into a small peripheral vein in the arm or leg, as is most intravenous access. Central lines are usually placed in the internal jugular vein on the neck, in the subclavian vein on the chest, or in the femoral vein on the inside of the upper thigh near the groin. Central lines are used when rapid infusion of fluids or medication is needed or when the medication would be harmful to smaller veins because of the medication's high-flow rate or its toxic effects (as occurs with some chemotherapy drugs). A central line is also used when a patient is severely dehydrated, thus making access difficult into the smaller veins in the arms or legs . Plus, a central line would allow a larger volume of fluids to be given.
