RN2B..when you say they don't work well,do you mean they are clotting off completely or that you just aren't getting good flow rates? Have you tried a TPA dwell to remove the fibrin build-ups?
My original question was inspired by my facility's reaction to this year's heparin scares/shortages. The initial knee-jerk reaction was to say no heparin in any line. Period. Just use saline for everything. That included PICC's,ports,all CVC's and HD cath's. Our HD people,wisely, started using Citrate 4% and that's what we in the ICU's used for our CRRT patients. So 2 weeks ago,when I took a pt. off CRRT,I locked the line with Citrate. A few rooms down,a different nurse used Heparin after his machine crashed (we can use Heparin again according to the powers that be). Then a different pt. received HD by the HD staff and her line was locked with TPA since she's had some occlusion problems in the recent past.
I was hoping to hear from someone involved in the trials for some of the new solutions,like Taurolidine,high-dose Citrate (40%) or the methyline blue/citrate combination.
