Which basic principle is crucial for the care of any central catheter?

Maintaining patency is crucial for the care of any central catheter because it ensures that the catheter remains open and functional for medication delivery, blood draws, and other necessary procedures. Patency is vital to prevent complications such as thrombosis (clot formation within the catheter), which can lead to obstruction, discomfort, or even infection. Regular flushing with saline or heparin helps keep the catheter free of clots and ensures that it is always ready for use.

In addition, maintaining patency is directly related to preventing infection, as a blocked catheter may require manipulation that increases the risk of introducing pathogens. By ensuring that a central catheter is patent, healthcare providers can effectively manage a patient's treatment plan, enhancing overall safety and efficacy during the course of IV therapy.
