What should be done if swelling is observed during catheter use?

When swelling is observed during catheter use, the most appropriate action is to assess for possible complications. Swelling can indicate various issues, such as infiltration or thrombosis, which can lead to more serious complications if not addressed promptly. Evaluating the cause of the swelling allows healthcare providers to determine the next steps needed to ensure patient safety and catheter efficacy.

If swelling is present, it is important to examine the site carefully for signs of infiltration, phlebitis, or infection, and to assess the patient's condition for symptoms like discomfort or changes in blood flow. This proactive approach is essential in preventing further complications, such as tissue damage or systemic reactions, which may arise if the catheter is left in place without proper evaluation.

In contrast, continuing to use the catheter, reinserting it into a different site, or ignoring the swelling could lead to aggravation of the underlying issue, risk of complications, and compromise patient safety. Therefore, assessing for possible complications is the critical step in ensuring proper vascular access management.
