What are you using in your transudced arterial lines, a Heparized solultion, if so what is your concentration OR nonheparinized saline?... Read More

    Ns for A-lines and regular flushes, Hep is only used for open-ended PICCs that aren't being used, and then we monitor their plt levels carefully.

    For our art and cvp pressurized lines we mix 500units in 500cc ns unless pt has a specific condition that would require us just to use the saline pressurized bags. Have not seen any heparin thrombocytopenia as of yet.

    We still use heparin in our flush bags. They are on pressure bags giving the 3ml/hr as mentioned. We (unfortunately) do not have a protocol to change to saline until their plts drop, or they have a positive Hep/plt antibody result.

    Our pts come up from OR with heparinized solution, but once it runs out or is time to change it, we use NS.

    normal saline on central/a lines

    We, too, use only normal saline in our arterial line pressure packs. I've never actually had an a-line clot off. Usually when they "go bad"(radial line), it's becasue the patient is bending their wrist too much. One time, though, I was taking care of a donor patient and we used the line for so many labs, it went bad.

    I was told that the reason we stopped using heparin in all lines was that "studies" show that heparin causes thrombocytopenia when used in lines.

    My last pt had HIT. The only place he got the heparin from was the dwells in the vas cath. And that's a very small amount. After 2 HD's pts plts went from 250 to 70.

    Im a new RN, and ive worked on two crit care places for my first two rotations. In the general ICU, normal saline is used, however in the cardio-thoracic ICU (where 95% of pts are post CABG, MVR or AVR) they use the heparin as mentioned above.
    Both units use pressurised bags to give about 3ml/hr (more really though, as we use their art lines to take blood regularly for BSL's...).
    I have only seen one episode of HITs, and interestingly that was in the cardiac ICU, where a guy was transferred from another (less major) metro hospital with cardiogenic shock (he had EF of 8%..and various other ailments!). However, he was also on bd sc heparin 5000u, so the 3ml/hr was probably minimal in comparison.

    Ive always kinda wanted the research of whether one or other was more effective, seems odd two different units in the same hospital (actually they are so close they share walls!) have different protocols.

    my unit has now switched for saline for every line.. art, peripheral iv and central lines! only dialysis lines use sodium citrate, but we are heparin free! (i'm sure it's because of the increased HITT positive patients these days)
