According to the good ol nursing "rules of the road," TPN is given through a virgin IV line (never used) and only that line. Or at least that's what hospital protocol is telling me. When I looked online I also noticed that most TPN is placed through a central line and that line has a high rate of infection, hence I can understand why you would only administer TPN through said line.
However in clinicals my patient has TPN through a PICC line and I was wondering if this same principle applies with a PICC. Particularly if the patient is getting secondary infusions of electrolytes. Could you infuse the electrolytes through the same line? If not, why not? What are the other risks with TPN through a PICC line?
Any help would be great. Thanks!
