The new adsorbing membrane for continuous renal replacement therapy (CRRT), oXiris, can reduce plasma cytokines and endotoxins in septic shock patients with severe acute kidney injury, compared with standard membranes. However, its hemodynamic stability or benefits have not been thoroughly evaluated although this is reasonable.

The new adsorbing membrane for continuous renal replacement therapy (CRRT), oXiris, can reduce plasma cytokines and endotoxins in patients with severe acute kidney injury or sepsis, compared with standard membranes. Based on this benefit, the use of oXiris may confer better outcomes than other membranes.

The patient outcomes include cardiovascular, respiratory, renal, and overall survivals, but this information of oXiris are insufficient. Although cytokine and endotoxin removal rates are great in oXiris, the beneficial effects on the hard outcomes are needed to use oXiris in real clinical practice.

The inflammatory and cardiovascular systems have intensive crosstalk, and thus if there are remission in inflammatory process, the patients can have hemodynamic stability. Regarding this, the investigators would like to compare the hemodynamic stability between oXiris and other standard membrane such as polysulfone, using our new real-time monitoring registry.

Inclusion Criteria:

• Aged ≥ 18 years
• Sepsis related acute kidney injury requiring continuous renal replacement therapy

Exclusion Criteria:

• No monitoring of blood pressure and ECG

Adult patients who have severe acute kidney injury and require continuous renal replacement therapy because of hemodynamic instability.
