What is the definition of infiltration in the context of vascular access?

Infiltration is defined as the unintentional seepage of fluids into surrounding tissues, typically occurring when intravenous or vascular access is compromised. This can happen if a needle or catheter is improperly positioned, allowing fluids to escape from the vessel and leak into the surrounding tissue. This situation often leads to pain and swelling at the site of infiltration, as the excess fluid accumulates in the tissues, causing discomfort and potentially affecting circulation.

Recognizing infiltration is crucial in clinical settings, particularly for patients undergoing treatments like dialysis, to ensure prompt intervention and reduce any potential complications from the condition. By identifying infiltration early, healthcare providers can take appropriate measures, such as adjusting the access site or providing supportive care to alleviate symptoms.
