ABSTRACT
Acute renal failure (ARF) is a common problem in the intensive care unit (ICU) and, despite significant improvements in the care of critically ill patients, the mortality from this complication remains over 50%. Over the last two decades there has been an evolution in the field of hemodialysis and, consequently, our approach to the treatment of ARF. The use of new devices and techniques has allowed us to achieve better-tolerated and more efficient renal replacement therapy (RRT).
