Which vascular access device should not be used for home parenteral nutrition (HPN)?

• A. Midline catheter
• B. Hickman catheter
• C. Peripherally inserted central catheter
• D. Implanted port

Answer: (A)

Delivering home parenteral nutrition requires central venous access because PN solutions are highly concentrated and need to be delivered into the central circulation to avoid irritation of peripheral veins. A midline catheter stays in a peripheral vein with its tip not reaching the central veins, making it unsuitable for long-term, high-osmolar PN. Midlines have limited dwell times and a higher risk of phlebitis with PN, which is not acceptable for home use. In contrast, central venous access devices such as a tunneled Hickman catheter, a peripherally inserted central catheter, or an implanted port place the tip in a central vein, tolerate the osmolarity and volume of PN, and are designed for long-term use in home settings.
