A Prospective, Interventional Study to Investigate the Impact of Different Citrate Concentrations as Locking Solutions on Development of Biofilm and Function of Hemodialysis Catheters

AIM OF THE STUDY:

The aim of the study is to compare the impact of two different concentrations of trisodium citrate solution (30% and 4%) on the formation of biofilms in hemodialysis single-volume jugular hemodialysis catheters and to determine the effectiveness of prevention of dysfunction of hemodialysis catheters.

Investigators will compare the influence of two different concentrations of trisodium citrate solutions as a locking solutions for hemodialysis catheters on the formation of intraluminal biofilm, the growth of microorganisms in the lumen of the hemodialysis catheter, and the occurrence of dysfunction of hemodialysis catheters in the same patient at the same time, under the same conditions as the same length and volume of hemodialysis catheters, catheter insertion time, duration of dialysis procedures, sex, age, co-morbidity, therapy and the presence of an infection.

BACKGROUND:

The population of patients this study will include are the ones who are being treated or are supposed to start the hemodialysis treatment at the Center for Acute and Complicated Dialysis, Department for Nephrology, UKC Ljubljana and for vascular approach have newly inserted or for any reason newly replaced two single-hemodialysis catheter to the left or right inner jugular vein.
