How do I know if my PICC line stopped working?

A Peripherally Inserted Central Catheter (PICC) line is a long, thin tube inserted through a vein in the arm and advanced to a larger vein near the heart. It's used for prolonged intravenous access. A PICC line may stop working due to complications such as occlusion, dislodgement, or infection. Clinicians typically look for signs like difficulty flushing or drawing blood, changes in the position of the external portion of the catheter, or swelling and pain at the insertion site. Occlusion is often due to blood clots or drug precipitates, which can block the line. Dislodgement might lead to changes in catheter length visible outside the body. Infection signs might include redness, warmth, or drainage at the insertion site.

Standard evaluation often involves assessing these symptoms and may include imaging or attempting to flush the line with a saline solution. Risk factors that healthcare providers assess include the duration the line has been in place and the patient’s overall health status. Anyone with concerns about their PICC line should discuss their specific situation with their healthcare provider.
