We have used trialysis at LSU primarily for stem cell harvest or procedures requiring BFR of 100 or so

The routine care is provided by the BMT unit, they flush and lock catheter with 1:1000 heparin after every use

We ha e used these for over 4 years, have not seen more infections with these, the patients typically have these for. Month or two

In my experience about 500 patient, We used saline + heparin only 500 UI to flush and lock catheter, after 1-2 months, there are no infection. So I think, we no need antibiotic for lock the catheter if we sure about the aseptic prepare.

We use quite a few of these. A number are used for BMT patients needing stem-cell harvest, and are typically placed by IR. Some are placed for AKI/ESRD patients who don’t have other venous access, but we only use these short-term. Our institution (like most I’m sure) is petrified of CLABSI, and strongly discourages femoral catheters for more that a few days; and similarly, non-tunneled IJ catheters, which are known to have a higher rate of infection (besides being miserable for the patient). Trialysis catheters placed via subclavian vein can be used longer-term with lower risk of infection than IJ or femoral, but for obvious reasons, we avoid SCL lines, even in AKI patients who we don’t expect to remain on dialysis. Furthermore, the one extra lumen is not enough to serve the needs of most patieints in ICU with MODS. Therefore, when we have a patient with AKI or ESRD who needs more than HD access, we prefer to place 2 tunneled IJ catheters simultaneously, with the second being a 6-Fr powerinjectable double or triple-lumen cuffed catheter (Bard PowerLine or Medcomp ProLine). We try to do this as our 1st access procedure whenever possible, rather than placing a temporary non-tunneled catheter and then doing tunneled lines at a later date; except in patients with active infection or otherwise too unstable to bring to angio-suite for procedure.

When we do place a Trialysis catheter, we treat it just like any other temorary HD catheter: exit-site care with chlorhexidine impregnated Biopatch; lock HD lumens with 1000 u/cc heparin, and flush/lock the 3rd infusion lumen with saline or 100 u/cc heparin. No anti-infection locking solution.

For those of you using Trialysis catheters for long periods of time (weeks/months), what vein are you entering?

Our institution (Houston Methodist) uses a lot of Tiralysis catheters. They seem to perform better than the Quintons.
