How should open lumens be managed when a CVC is not in use?

When a central venous catheter (CVC) is not in use, it is essential to manage open lumens appropriately to prevent contamination and infection. Covering the open lumens with sterile end caps is the correct management strategy. This practice helps maintain sterility and protects the lumens from exposure to environmental contaminants, which could lead to infection.

Sterile end caps serve as barriers to microorganisms, effectively sealing the catheter's access points. This minimizes the risk of pathogens entering the bloodstream, which is particularly crucial for patients with CVCs, as they are already at a heightened risk for central line-associated bloodstream infections (CLABSIs).

Other options, such as covering with gauze or taping securely, do not provide the same level of protection against microbial contamination as sterile end caps. Leaving lumens exposed poses the greatest risk, as it directly invites potential microorganisms to enter the catheter. Therefore, the practice of utilizing sterile end caps is vital in infection control protocols regarding CVC management when not in use.
