I am designated to write a PICC care policy for my hospital. I am trying to find some supports to back up my point ofÂ flushing the PICC with 10mL NS even thought there is a continuous IV line (TPN, PPN, TKO...). I remember I read somewhere that TPN, PPN or Lipid can precipitate and eventually clot the PICC. Dilantin infusion or IVP can also clot up the line. So I thought it would be better to flush the PICC regularly every 12 hours AND after each use, no matter what. So here are my questions. Thanks a lot for any input.
1) ShouldÂ I routinely flush a continuous IV line?
2) If yes, how can I do it, disconnect the IV line then flush or flush through the IV port that is closest to the PICC?
3) Do you have any literature to support this kind of practice?
