When should a PIV be replaced?

A peripheral intravenous (PIV) catheter should be replaced as soon as possible if it has been placed in certain areas of the body, particularly those that are known to have a higher risk of complications or injury. This can include sites that are subject to movement or pressure, such as the wrist or the antecubital fossa. Additionally, certain sites may have a higher likelihood of infection or catheter-related complications due to their anatomy or function.

Replacing a PIV catheter proactively in these areas helps to prevent complications such as thrombophlebitis or infiltration and ensures that the patient maintains effective vascular access. Factors such as the condition of the insertion site, the duration of catheter use, and any signs of complications should be assessed regularly to determine the appropriate timing for replacement. Thus, this option emphasizes the importance of site assessment and timely intervention in maintaining vascular access safety and efficacy.
