What is the recommended schedule for routine central venous catheter (CVC) replacement?

• A. Daily replacement
• B. Every 7 days
• C. Only when indicated
• D. Never replace a CVC

Answer: (C)

Routine replacement of a central venous catheter on a fixed schedule is not recommended. The important idea is to keep the catheter in place as long as it remains necessary and functional, while minimizing opportunities for infection and other complications. Replacing a catheter just because a certain number of days have passed does not reduce infection risk and instead adds the risks of another procedure and line manipulation. The appropriate approach is to remove or replace the catheter only when there is a clear indication, such as malfunction or occlusion, suspected or confirmed catheter‑related infection, local infection at the insertion site, thrombosis affecting flow, or when the line is no longer needed for patient care. To lower infection risk overall, maintain strict aseptic technique during access, ensure proper skin antisepsis, and regularly reassess the line’s necessity so you’re using it only as long as it’s truly needed.
