    Hey Terri 🙂

    We do instruct our nurses to waste when they are drawing coag labs, as these will all be affected by the presence of heparin in the sample.  We have several kids on Lovenox with ports/PICC’s, and most of our small severe factor 8/9 deficiency kids have ports.   Otherwise, for our onc kids having non-coag labs, we do not waste.

    We are currently transitioning our program to a hospital that has never previously housed pedi heme/onc.  Fun fun fun!

    The non heme/onc nurses there currently withdraw and waste the heparin from a hep-locked CVL prior to flushing it with saline due to a concern of anticoagulating the patients over time.

    This is not currently our practice at all.  We flush the small amount of heparin through the line with our initial saline flush mixed with blood return to check placement.  My concern with wasting the heparin prior to flushing is the additional line entry to the process.

    Is anyone out there wasting their heparin?
