A PICC line, or Peripherally Inserted Central Catheter, is a long, thin tube inserted into a vein in the arm. It is used to deliver medications, fluids, or nutrients directly into the bloodstream. This type of catheter is often chosen for patients who need long-term intravenous therapy, as it can remain in place for weeks or months. The PICC line is inserted by a trained healthcare professional using sterile techniques. It is typically placed in a large vein, allowing for better blood flow and reducing the risk of complications. Regular monitoring and care are essential to prevent infections and ensure proper function.
