Cath flo question

  1. How do you all use cath flo when a PICC is clogged.
    I'm aware of how to dilute it, then you instill it and wait for 30 mins. But what happens when you try to instill the cathflo and it won't flush?:spin:

    If you cannot instill it can not properly do its job. There are two techniques to work it in . You can use a syringe method or a stopcock method. IF the occlusion is caused by a precipitate you often can not get the Tpa in nor will it work. I am sure there is a tutorial somewhere,but first check your policy and prodecure. I have ours done with step by step directions.

    I don't know what the syringe method or the stopcock method is. I'll look around for instructions on the floor for cathflo, although finding stuff like instructions seems next to impossible, thats why I posted here.

    OK I will outline the syringe method as this is my favorite as weel as our team favorite

    1. Assess the catheter to determine the level of dysfunction and the possible cause. What is the line being used for? Was there a recent blood draw? How long has the line been in place? Does the line have a history of dysfunction? it will always help to get his brief history b/c if you can determine that it is a precipitate the Tpa will not work. If there was an am blood may be caused by blood clotting in the lumen. You get the idea. Remember that a PWO (persistant withdrawl occlusion) defined as an ability to easily instill but not withdraw should also be treated. A lumen of a CVC should never be left occluded as this puts a patient at an increased risk for infection...attempts to clear it (with a thrombolytic an agent to treat a precipitate) should be made or the catheter removed.
    2. Once you have determined that you want to try Tpa this is wha to do:

    a. reconstitute the Tpa with 2.2 ml sterile water ( make sure it is SW and nothing else) Do not shake
    b. Draw up the dose in a 10 ml syringe
    c Instill this at the hub or though the needleless cap. I prefer hub to hub as this eliminates the possibility of a cap problem. Cleanse the hub or cap with a 15 sec alcohol scrub and attach the syringe. IF unable to instill b/c you have a complete occlusion withdraw the 10 ml syringe back to the 6-8 ml mark keep doing this several times and then try to instill a little (NEVER Force it). You may have to pull back multiple multiple times before you can get a little in. Once you get a liitle in the floodgates open up and you can get the rest in. Personally I find it is easier to get the drug in with silicone catheters as compared to polyurethane but be careful not to push to hard on the silicone catheters as you can make pinholes anywhere along the catheter or damage the tails.
    d.Once you get the 2 mg in label the line....tpa in line do not use.
    e return in 30 minutes and check for results. It has beeb effective if you are able to easily withdraw blood. If it is still sluggish push it back in. You can check every 30 min if you want but if the line is not needed right away I tend to to leave it for another 90 minutes
    f. Once you have established a good blood return.....withdraw 5-10 ml blood and flush with 10-20 ml normal saline using a push pause pulsatile flush then a final flush of Heparin if you use it. re-apply cap if needed.
    g A repeat dose may be needed.

    I hope this is a better answer for you and if any more ?s I would be happy to share my experiences :spin:

    As a new NICU nurse, I would love some clarification for the BEST way to prime the IV cassettes for minimal air, especially since most of these are going into central lines. Most nurses invert the cassette and pull out the white knob and then turn the cassette back up right after the first chamber starts to fill, others do this process so quickly, I am not sure what the most optimal way to do this is? Should you immediately drop the cassette as soon as you see it filling OR wait for it to fill completely before putting it upright?
