Abstract

Objective: to confirm the relationship existing between using or not using sodium heparine and filter clotting in Continuous Extrarenal Depuration Techniques (CEDTs).
Materials and method: a transversal descriptive study conducted in the Intensive Care Unit (ICU) during two years. All patients who underwent CEDT during that period were included in the study. Sociodemographic variables were collected, as well as the use of sodium heparine, duration, reasons for removal, and filter clotting. Descriptive statistics and statistical inference were used, through Student’s t Test and Mann-Whitney U Test.
Results: a sample of 50 patients and 162 filters was obtained. Heparine was used in 66% of patients. The mean duration of the filter with heparine was 27.1 vs. 19 hours in those were it was not used (p= 0.004). The main reason for removing filters was clotting, both for those where heparine was used (71%), and for those where it was not used (70%).
Conclusions: the use of sodium heparine in CEDT increases the mean life of the filter. Filter clotting is the most usual reason of removal. The use of sodium heparine entails a delay in filter clotting.
