What is the role of heparin in maintaining CVAD patency?

• A. It is used to inflate the CVAD
• B. It is used to flush the CVAD to prevent clotting
• C. It acts as an antibiotic for preventing infection
• D. It helps in securing the catheter in place

Answer: (B)

Heparin plays a critical role in maintaining the patency of a Central Venous Access Device (CVAD) by being used to flush the device, which prevents clot formation within the lumen of the catheter. When administered correctly, heparin acts as an anticoagulant, inhibiting the coagulation process that can lead to thrombus development. This is especially important in preventing occlusions that can complicate the use of the CVAD, ensure unobstructed flow, and enhance the longevity of the catheter. Flushing with a heparin solution after the administration of medications or fluids helps ensure that the line remains clear and reduces the risk of clotting that can occur when blood stagnates in the catheter. Maintaining patency through flushing is a standard care practice that is essential for the effective use of CVADs in clinical settings.
