Continuous renal replacement therapy in intensive care unit



Acute renal failure (ARF) requiring dialysis is a common complication of patients in intensive care unit (ICU). Dialysis can be performed with either intermittent hemodialysis (IHD) or continuous renal replacement therapy (CRRT). CRRT is associated with less hemodynamic instability. Therefore, it is preferred in critically ill and hypotensive patients in ICU. However, current evidence does not demonstrate the superiority of CRRT over IHD. Both methods for renal replacement therapy are complementary and the choice of dialysis in ICU should be individualized based on hemodynamic stability of patients and local expertise.
