Comparison of a TauroLock™ Based Regimen to 4% Citrate as Lock Solution in Tunneled Haemodialysis Catheters for the Prevention of Bacteraemia and Dysfunction

(CitraFlow™ 4%, MedXL, Montreal, Canada) will be injected in each of the 2 lumens of the tunneled catheters after each dialysis session (2ml/lumen, 3x/week).

After the first two dialysis sessions of the week (before the short intervals) 2 ml of TauroLock™-Hep500 containing 1% (cyclo)-taurolidine, 4% citrate and 500 IU/mL heparin will be injected into each of the two lumens of the tunneled catheter. After the third dialysis of the week, thus before the long interval, 2 ml of TauroLock™-U25.000 which contains 1% (cyclo)-taurolidine, 4% citrate and 25.000 IU urokinase will be applied into each lumen.
