AbstractThe evolution of renal replacement therapy has permitted the treatment of critically ill patients with acute renal failure. In intensive care settings, continuous renal replacement therapies have been shown to be better tolerated and clinically useful. Continuous hemofiltration is now performed with blood pumps and double-lumen venous catheters, thus avoiding the complications found in previous arteriovenous treatments. The use of countercurrent dialysate flow has overcome problems related to low treatment efficiency. High clearances can now be obtained during continuous hemodialysis or hemodiafiltration, and adequate blood purification can be achieved even in severely catabolic patients. New replacement solutions allow for a more effective correction of acidosis and electrolyte imbalances. Finally, newly designed machines permit continuous therapies while minimizing staff workload. Continuous therapies are today moving toward newer indications and applications. The ability to remove proinflammatory substances by filtration and/or adsorption has opened a series of potential indications. The concept that renal support and protection take place during hemofiltration suggests that very early use of this technique is desirable, even before the onset of oliguria or azotemia.
