“Whatever a PICC line is....”
I think it’s the needle they stick in your arm to insert IV liquids. (Not sure.)
More serious than a needle in the arm .....
A peripherally inserted central catheter (PICC or PIC line), less commonly called a percutaneous indwelling central catheter, is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g., antihypotensive agents a.k.a. pressors). It is a catheter that enters the body through the skin (percutaneously) at a peripheral site, extends to the superior vena cava (a central venous trunk), and stays in place (dwells within the veins) for days or weeks.
I just found out you’re right.
