How do PICC lines differ from central line catheters?

PICC lines, or Peripherally Inserted Central Catheters, are specifically designed to be smaller gauge catheters that are inserted through a peripheral vein, usually in the arm, and threaded into a central vein near the heart. This placement allows for long-term venous access without the need for larger central line catheters, which are typically inserted directly into major central veins like the subclavian or jugular veins.

The smaller gauge of a PICC line is advantageous for patients who need long-term intravenous (IV) access for medications, fluids, or nutrition, while minimizing discomfort and complications associated with larger catheters. PICC lines can remain in place for weeks to months, therefore serving well in scenarios requiring ongoing therapy, like chemotherapy or prolonged antibiotic treatment.

In contrast, options regarding larger sizes, short-term use only, or pressure handling are not accurate descriptions of PICC lines. Understanding the fundamental characteristics of PICC lines versus central lines is crucial for clinical application in patient care, particularly when it comes to selecting the appropriate vascular access for different medical scenarios.
