Evaluation of the Effectiveness of Continuous Venovenous Hemodiafiltration Appli̇ed With Oxiris and AN69 Membranes in Patients With Septic Shock-Related Acute Kidney Injury

Abstract

Background and objectives: AN69 and Oxiris are filters used in continuous renal replacement therapy. In this study, we aimed to research the effects of these filters on blood cell counts, blood biochemistry, inflammation indicators, clinical status and mortality of patients diagnosed with septic shock-related acute kidney injury. Method: Between March 2019 and October 2019, 42 adult patients (Group 1: Oxiris (n = 21) or Group 2: AN69 (n=21)) with septic shock-related acute kidney injury and received continuous venovenous hemodiafiltration (CVVHDF) in the intensive care unit were included in the study and their results were prospectively observed and compared. The data at the begining of CVVHDF (pre-CVVHDF) and 24 hours after the onset of CVVHDF (post-CVVHDF) were recorded.Results: In the comparison of the pre- and post-CVVHDF values in Group 1, there was a statistically significant decrease detected in the procalcitonin (p = 0.04) and noradrenaline infusion rate (p = 0.02) levels. In terms of the other data there was no statistically significant difference between pre- and post-CVVHDF values in Group 1. In the comparison of the pre- and post-CVVHDF values in Group 2, there was a statistically significant decrease detected in the urea (p = 0.04), platelet count (p = 0.02) and procalcitonin (p = 0.002) levels. There was no statistically significant difference between pre- and post-CVVHDF values in terms of the other data in Group 2. There was no statistically significant difference between the groups in terms of mortality. Conclusions: CVVHDF with Oxiris filter causes a statistically significant decrease in noradrenaline infusion rate. Therefore, we think that the use of CVVHDF with Oxiris filter applied for septic shock-related acute kidney injury will save us time and increase the improvement in the treatment.
