Which catheter is considered suitable for long-term use?

The peripherally inserted central catheter (PICC line) is designed specifically for long-term use in patients requiring prolonged intravenous therapy. It can remain in place for weeks to months, making it a viable option for patients who need ongoing treatment such as chemotherapy, antibiotic therapy, or nutrition support. The design of the PICC allows it to access larger central veins, which can accommodate higher volumes of fluid and medications than standard peripheral IV lines.

In contrast, a standard peripheral IV line is typically intended for short-term use—usually a few days—due to the risk of complications like phlebitis and infiltration.

While both subclavian central vascular lines and internal jugular catheters can be used for medium to long-term access, they generally involve more significant risks and complications related to placement and maintenance compared to a PICC line. Therefore, the PICC line stands out as the most suitable option for patients needing long-term intravenous access.
