Why is it important to open the roller clamp and allow solution to run rapidly for 30 to 60 seconds after changing tubing?

Opening the roller clamp and allowing the solution to run rapidly for 30 to 60 seconds after changing the tubing is primarily important for clearing the catheter of any blood that may be present in the lumen. This practice helps prevent complications associated with blood clots or infections. When tubing is changed, there is a risk that residual blood may be left in the catheter, which can lead to occlusions or biofilm formation if not properly cleared. By flushing the catheter with an appropriate volume of intravenous fluid, any stagnant blood can be washed out, ensuring that the pathway for fluid administration is clear and that the system remains free from potential blockages or contamination.

This practice also helps to check for leaks in the system before continuing with fluid administration, ensuring that the IV line is functioning correctly. While it is crucial to ensure proper functioning of the infusion system and to prepare the patient for any subsequent medications, clearing the catheter of blood takes precedence as a fundamental safety measure in IV therapy.
