GONZALEZ MARTINEZ, Mª del Rocío et al. Study of the efficacy of a taurolidine and 4% citrate lock solution for haemodialysis catheters in the prevention of infection and thrombosis. Enferm Nefrol [online]. 2014, vol.17, n.1, pp.22-27. ISSN 2255-3517.

The use of central catheters has increased significantly despite their greater morbi-mortality compared to AVF. The main complications are thrombosis, bacteriaemiasepsis, and limitation of dialysis efficacy, reducing quality of life for patients and increasing the healthcare cost. In our unit, 5% heparin sodium was previously used as lock solution and we currently use TauroLockTM Hep 500®, composed of (cyclo)-taurolidine (biocompatible antimicrobial agent) 4% citrate and heparin 500 UI/ml. Objective: To verify the efficacy of Taurolock in reducing the incidence of intraluminal colonization and thrombosis compared with 5% heparin sodium. Material and method: We carried out a longitudinal observational cohort study and we analysed intraluminal colonization, thrombosis, biofilm and use of antibiotherapy. Results: We observed an improvement in catheter permeability, a reduction in the use of urokinase, reduction in unipuncture sessions and in use of antibiotic. Conclusions: Our study shows that using a lock solution that contains taurolidine as an antimicrobial agent for haemodialysis catheters can significantly reduce the incidence of catheter-related sepsis. Taurolidine appears to be effective and safe and does not entail risks or side effects. The addition of 500 iu of heparin to the lock solution together with 4% citrate has reduced thrombotic events by reducing the use of fibrilolytics and eliminating completely the use of unipuncture, presenting an improvement in dialysis efficacy.
