ABSTRACT
INTRODUCTION: Citrate 4% is an alternative to heparin as catheter-locking solution in chronic hemodialysis patients. We compared catheter dysfunction episodes, dialysis adequacy, plasminogen-tissular activators use and costs according to catheter-locking solution in our centre. METHODS: Prospective, monocentric, cohort study (NephroCare Tassin-Charcot) on 49 prevalent patients in chronic hemodialysis. Two main groups were formed according to the prescription of catheter-locking solution at the beginning of the study (03/02/2016) and followed until 05/10/2016: heparin (n=26) and citrate (n=22). RESULTS: The number of diabetic patients was higher in the citrate group (12/22) than in the heparin one (5/26; P=0.025). The 2 groups were comparable for the other studied variables. We didn't observe any difference in terms of catheter-dysfunction (4.23 versus 4.14% in heparin and citrate groups, respectively; P=1.0) and dialysis adequacy. The prescription of citrate was associated with lower TPA uses (1/604 versus 14/946; P=0.022) and lower costs (1.42 for one session versus 2.94 ). CONCLUSION: Administration of citrate 4% as a catheter-locking solution is not inferior to heparin in terms of catheter-dysfunction episodes, is associated with similar dialysis adequacy results, lower plasminogen-tissular activators uses and reduced costs in chronic prevalent hemodialysed patients.
