What is a contraindication specific to PICC lines?

A contraindicative factor specific to PICC lines is the presence of an existing central line on the same side. Inserting a PICC line in an arm where another central line already exists could lead to complications such as increased risk of thrombosis, infection, or impaired blood flow. It is critical to maintain clear and unobstructed venous access, and the presence of multiple central lines in the same limb can compromise this, making it problematic to ensure patient safety and effective treatment delivery.

In contrast, while impaired kidney function and the need for immediate hemodialysis could pose challenges in patient management, they do not inherently contraindicate the placement of a PICC line. Additionally, a previous minor surgery on the same arm usually does not pose a significant barrier unless there are complications from the surgery that would affect vascular access.
