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.
