Practice patterns in the management of acute renal failure in the critically ill patient: an international survey

Several controversies have developed over acute renal failure (ARF) definition and treatment: which approach to patient care is most desirable and which form of renal replacement therapy (RRT) should be applied is an everyday matter of debate. There is also disagreement on clinical practice for RRT including the best timing to start, vascular access, anti-coagulation, membranes, equipment and finally, if continuous or intermittent techniques should be preferred. In this lack of harmony, the epidemiology of ARF has recently displayed an outbreak of cases in the intensive care units and nephrologists and intensivists are now called to work together in the case of such a syndrome.
