How often should a PICC line be flushed?

A PICC line, or peripherally inserted central catheter, should be flushed before, between, and after the administration of medications to maintain patency and prevent blockage. This flushing helps ensure that the line remains clear and allows for the safe delivery of medications without any risk of precipitate formation or medication interaction within the line itself. Additionally, flushing with a saline solution before infusing medication helps clear any residual medication that may have been in the line from a previous use, ensuring that the full dosage of the new medication is delivered to the patient effectively.

Regular flushing as described also aids in preventing thrombosis or catheter-related infections, which can occur if the line is not properly maintained. Some other options may suggest less frequent flushing, but these would not adequately support the requirement for maintaining the functionality and safety of the PICC line throughout the medication administration process.
