Acute renal failure (ARF) is a frequent complication in patients admitted to the Intensive Care Unit (ICU). It usually appears associated with other organ dysfunctions in the context of a syndrome of multiorgan dysfunction.
The management of ARF in critically ill patients often requires renal replacement therapy (RRT) that is intended to replace impaired renal filtration.
Since the appearance of RRT more than 30 years ago, there has been a notable advance in the knowledge acquired and the improvements in the management of patients with ARF. However, the mortality of ARF continues to be high and there are many controversies and little clarity when applying RRT, such as the moment of initiation and withdrawal, the treatment modality, the dose, the type of anticoagulation, etc. In recent years, numerous studies have attempted to clarify the lack of consensus on many of these aspects.
