Impact of a Tunneled Hemodialysis Catheter With Endexo® Technology on Catheter Dysfunction Compared With Historical Catheter Dysfunction Data in Standard Catheters

Impact of a Tunneled Hemodialysis Catheter With Endexo® Technology on Catheter Dysfunction Compared With Historical Catheter Dysfunction Data in Standard Catheters (Silicone or Polyurethane): A Pilot Study
There is evidence that central venous catheters made of the permanent and non-eluting integral polymer Endexo® are more resistant to intraluminal thrombosis.
This has a direct reducing effect on catheter malfunctions.
Indirectly, due to reduced handling of the dysfunctional catheter, this may lead to a diminished rate of catheter related infections.
Since catheter malfunctions and infections represent leading complications in a dialysis population, dialysis catheters produced with Endexo® technology have the potential to have beneficial clinical effects.
In addition to improving patient outcomes, this could also reduce overall costs.
In this pilot study the tunneled hemodialysis catheter BioFlo Duramax with Endexo® technology (Merit Medical, Utah, USA) will be compared with historical catheter dysfunction rates in standard tunneled dialysis catheters (silicone or polyurethane) in chronic dialysis population.

Aktiv komparator: Insertion of a tunneled hemodialysis catheter with Endexo® technology for haemodialysis treatment
Study participants will be recruited among those patients with the need of insertion of a tunneled catheter to perform hemodialysis who attend the recruitment site (Medical University of Vienna, Department of Internal Medicine III, Division of Nephrology and Dialysis) for routine care.
A tunneled hemodialysis catheter BioFlo Duramax with Endexo® technology (Merit Medical, Utah, USA) will be implanted.
As a standard catheter lock solution 4% citrate (applied in each of the 2 lumens after each dialysis session) will be used.
Care of the tunneled catheter in the study sites will be followed established standards including dressing changes, exit site care and hygiene.
After each hemodialysis session the exit site will be inspected and covered with 2.0% chlorhexidine dressing (Tegaderm CHG, 3M, Neuss, Germany).
Chronic haemodialyisis treatment will be held in a regular setting based on the patient's dialysis requirements.

Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
Catheter dysfunction
Tidsramme: From enrollment to the end of treatment at 6 months
|
Catheter dysfunction will be defined as inadequate blood flow during dialysis (blood flow < 200mL/min or >30% less than the average of the previous 10 sessions) and if present before or during dialysis, patient repositioning or reversal of catheter lines will be performed.
If not successful, Taurolock Urokinase with a final Urokinase of 50.000
IU will be instilled per lumen either with a 30-minute dwell time before dialysis or as CLS in the inter-dialytic time as rescue.
If urokinase is not effective after repeated use the dialysis catheter will be removed.

Catheter-related infections will be defined as positive bacterial blood culture drawn from the dialysis catheter in a symptomatic patient with fever or chills associated with dialysis and no apparent other source of infection.
Blood cultures will be taken using aseptic technique from each lumen of the tunneled catheter and in addition from a peripheral vein whenever possible to determine the differential time to positivity.
