In what scenario may an intravenous (IV) catheter need to be replaced?

The need to replace an intravenous (IV) catheter is important for maintaining proper catheter function and minimizing complications. Swelling at the insertion site often indicates potential issues such as infiltration or phlebitis. Infiltration occurs when the IV fluid leaks into the surrounding tissue rather than flowing into the bloodstream, which can lead to swelling, discomfort, and further complications. Phlebitis refers to inflammation of the vein, which can also manifest as swelling, redness, and pain.

Recognizing swelling as a sign that the IV catheter needs to be replaced is crucial for patient safety. Early intervention can prevent more serious complications and ensure that the patient continues to receive the necessary therapies effectively. Therefore, proper monitoring of the IV site and understanding when to replace the catheter is essential in patient care.
