What factor increases the risk of infection during IV therapy?

Frequent disconnection of infusion tubing significantly increases the risk of infection during IV therapy. Each time the tubing is disconnected, there is an opportunity for pathogens from the environment to enter the system. This interruption in the closed sterile pathway can introduce bacteria or other microorganisms, leading to possible infections at the insertion site or within the bloodstream. Maintaining a clean and continuous system is crucial in IV therapy to minimize infection risk, and frequent disconnections contravene this principle by exposing the system to external contaminants.

Other practices, such as using single-use, sterilized needles, performing regular dressing changes, and maintaining closed systems, are designed specifically to reduce the infection risk by ensuring sterile techniques and minimizing opportunities for contaminants to enter the IV line. These practices support the integrity of the IV delivery system, highlighting the importance of maintaining strict protocols in IV therapy.
