Hi I had a question regarding TPN. When TPN and Lipids are hung separately and the lipids are completed after 12 hours, and the TPN continues to hang, should the cap (maxplus) that the lipids were infusing into, be flushed with NS? Some say to backflush with the TPN solution, to prevent opening the system, but TPN is basically dextrose so would this not be an infection risk to leave a cap filled with TPN? Would it be best to flush the cap with NS after the completion of the lipids? Thanks for your input.
