What Are Intravenous Injections?
prevent air from entering the vein and allows for an estimate of flow rate. It’s one of the fastest ways to administer fluids and medications through the body. The vein for the intravenous injection is accessed by way of a hypodermic needle through the skin. Often times the needle is connected to tubing or to a syringe which allows for blood samples or administering fluids. Often IVs are placed on the back of the hand or in the arm, and in younger patients it is fairly common to administer an IV in the foot. Sometimes it’s necessary to administer medications near the heart or main circulatory system; this is called a central line, which feeds into one of the main veins that reach the heart (the inferior or superior vena cava).
