Aloha! When continuous fluids or medications are infusing 24 hours per day via a CVC, what is a recommendation for flushing non-tunneled central catheters and checking for blood return with aspiration. In the ICU this is often the case. All lumens are in use and to break a connection to flush and check for a blood return seems less than optimal and with potential for contamination.
What is your thinking on this specific case and what are your ICU nurses actually doing? Flush with tubing changes and injection cap changes? Flush whenever the med/fluid bag is changed? What (based on expert opinion - level 5) evidence is there for a recommendation? Our ICU nurses ask this question when we recommend flushing and blood return q shift.
Thanks for your thoughts.
