What is typically an indication that a central line needs to be replaced?

A central line replacement is typically indicated when there are visible signs of local infection. This includes symptoms such as redness, swelling, tenderness, or discharge at the insertion site. The presence of an infection can lead to serious complications, including systemic sepsis, making it crucial to assess the condition of the central line regularly. Prompt replacement of the line when infection is detected can help to prevent these complications and increase patient safety.

While an expired line, patient agitation, or dressing changes may indicate other necessary actions or assessments, they do not directly warrant the replacement of the central line. The expiration date pertains to the safety and integrity of the device rather than its immediate functionality. Agitation in a patient could stem from various unrelated issues, and changing a dressing is a routine procedure that does not in itself signify that a central line is compromised. Therefore, visible signs of local infection are the most direct and serious indicator necessitating a central line's replacement.
