Discontinuing Intravenous Fluids and a Peripheral Intravenous Line

Intravenous (IV) fluid administration and peripheral IV catheters (PIVs) may be discontinued for a number of reasons. The most common reason for discontinuing IV fluids is that the patient has returned to normal body fluid volume (euvolemia) and is able to maintain adequate oral fluid intake or is being discharged from the hospital. In addition, the Centers for Disease Control Guidelines for the Prevention of Intravascular Catheter-Related Infections (2011) recommends replacing PIVs every 72-96 h in adults to prevent the risk of infection or phlebitis. If the PIV becomes dislodged or if the insertion site demonstrates the signs and symptoms of infection, infiltration, extravasation, or phlebitis, the PIV should be discontinued and replaced. For pediatric patients, the Infusion Nurses Society recommends replacing the PIV only when the IV infusion site is no longer patent or when it demonstrates the signs and symptoms of complications. This video describes the approach to discontinue IV fluid administration and PIVs.

Peripheral Intravenous Catheter Insertion

The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to the Intravenous Nurses Society (INS), the feet should be avoided in the adult population because of the risk of thrombophlebitis. Venipuncture sites should be carefully assessed for contraindications, such as pain, wounds, decreased circulation, a previous cerebral vascular accident (CVA), dialysis fistulas, or a mastectomy on the same side. The median cubital vein and the cephalic vein in the wrist area should be avoided when possible. The cephalic vein has been associated with nerve damage when used for IV placements. The most distal site available on the hand or arm is preferred so that future venipuncture sites may be used if infiltration or extravasation occurs. This video will demonstrate the insertion of a PIV, including the preparation and attachment of an IV extension s
