Drawing blood from PICC lines - page 5

    I work in outpatient Oncology.

    We change dressings on PICC lines and draw labs using nothing smaller then a 10cc syringe.

    We flush with NS 5-6ml, then drawback and waste 5ml-6ml, then switch syringe and draw labs. We put vacutainer device on draw syringe, not on PICC port directly. You want to limit pressure on vital, small lines.

    We put new extensions on for our patients (because they go home and flush their own lines daily!), flush with NS and heparin.

    The only time we would not draw from a certain lumen of a PICC is if it is being used for TPN. Our patients usually come in with double lumen Hickman lines so we only draw off the lumen not being used for TPN.

    Again, that is in an outpatient setting. What is done as an inpatient may be different.

    It looks like it has been a while since this has been discussed.
    I have been reading the old posts and have a question.
    I am new to home health and need to draw blood on an adult from a PICC line:
    would I be better to use a 10cc syringe, flush with saline, draw waste, draw sample, flush with saline, flush with heparin OR attach a butterfly to the PICC port and attach the tubes to fill?

    Thank you.

    Flush with 10cc n/saline
    I then pull back on the same syringe and discard 10cc
    Collect sample
    Flush with 10cc n/saline x 2.
    Thats what I do in the hospital, we dont use heparin. Might be different for home health

    I work on an Oncology unit where many pts have PICC lines. there are 3 drs that routinely start them for us. These drs say that we are not to use them to draw blood for labs. They have said that this will cause the line to collapse. At my hospital, the RN has to do lab draws from central lines/PICCS. Some RN's abide by this and have lab stick the patient for labs. Other RN's draw blood from the PICC reason being,....they don't have any veins to begin with (which is why they have the PICC). I would like to get your opinion on this. I am a fairly new grad and have made waves with this. I used to draw blood from them until I learned the drs said not to. So now I refuse to do it and have lab do it (often times they are unable to get enough blood or can't find a good vein). Just curious. Thanks!
    The big risk of drawing labs from any central line, PICC, porta cath, sub clavian etc is the risk of infection caused by poor technique. This is very manageable, however. Just clean the cap properly and use aseptic technique. I work at MD Anderson in Houston. Hundreds of times per day labs are drawn from central lines ( PICC lines included ).

    The claim that the PICC will collapse is totally incorrect, never happens. Just keep it clean and saline or heplock flush per your hospitals policy. I do not want to minimize the infection risk ,but think about all of the chemo that we deal with as well as infection control issues with isolation patients. We are professionals and just have to do it right. So your doctors are wrong.
    Hope that my comments are helpful.
