Acid-base balance and substitution fluid during continuous hemofiltration.
Critically ill patients with acute renal failure usually present with an unstable acid-base balance, often leading to cardiovascular complications and multi-organ failure. Therefore, to prevent metabolic acidosis, acid-base balance must be normalized and maintained; these patients are primarily treated with continuous hemofiltration techniques using different replacement fluids to influence the acid-base values. Dialysate solutions can be an acetate-based, lactate-based, citrate-based or bicarbonate-based buffer. This article discusses the strengths and weaknesses of each type of hemofiltration replacement fluid.
