What is the recommended maintenance for CVAD lumens not being actively used?

• A. They should be left untouched
• B. They should be flushed periodically
• C. They should be disconnected from all solutions
• D. Only cleaned with alcohol wipes

Answer: (B)

Flushing CVAD (Central Venous Access Device) lumens that are not in active use is essential for maintaining their patency and preventing complications such as clot formation or occlusion. Periodic flushing helps to clear any blood or medication residue that could lead to blockage and ensures that the lumen remains open and functional should it need to be used again in the future.

In practice, flushing usually involves using a saline solution, and some protocols may suggest using heparinized saline depending on the specific type of CVAD and institutional guidelines. This routine maintenance step contributes to the long-term usability and safety of the CVAD.

The other options do not effectively support the necessary maintenance of unused lumens. Leaving them untouched could lead to complications as sediment or clots may form. Disconnecting them from all solutions might be required in some cases, but it does not address the need to keep the lumen patent. Cleaning them only with alcohol wipes does not provide the necessary flushing to ensure they are free from residue and remains effective.
