When would a nurse choose to use a peripheral IV over a central line?

The choice of using a peripheral IV over a central line is primarily guided by the duration the IV is needed and the type of fluids being administered. A peripheral IV is typically chosen for short-term therapy or when administering less viscous fluids. This is because peripheral IVs are easier and quicker to insert, provide adequate access for short-term treatments, and carry a lower risk of complications compared to central lines, which are more invasive and designed for longer-term use or more complex treatments.

For long-term therapy, a central line is usually preferred to minimize the risk of complications associated with peripheral access due to prolonged use. In patients with chronic kidney disease, while peripheral IVs can be used, there may be a preference for central access when long-term dialysis is required due to the need for a more stable and larger blood flow. In emergency situations, both peripheral IVs and central lines can be used, depending on the specific circumstances and immediate needs, but peripheral IVs are often utilized for their quick and straightforward application.
