Is it necessary to change NC after each blood draw from you PICC/Central line? I know it is imperative to change them if you cant get the blood out after flushing, and I know you remove the NC before blood cultures (and put new ones back on).
I have heard 2 different thoughts on this- 1)you can never get all of the blood out of the NC (even if you cant see any) and therefore should be changed. 2) More manipulation (changing NC each time) increases risk for complications.
I don't see this addressed in the standards (except of the blood cultures).
Thanks in advance!
