Dialytic Therapy

  • Rinaldo Bellomo

When acute renal failure (ARF) is severe, resolution can take several days or weeks. During this time, the kidneys cannot maintain homeostasis of fluid, potassium, metabolic acid, and waste products. Life-threatening complications inevitably develop. In these patients, extracorporeal techniques of blood purification must be applied to prevent such complications. These techniques, broadly named renal replacement therapies (RRT), include continuous hemofiltration (HF), intermittent hemodialysis (IHD), and peritoneal dialysis (PD). All of these techniques rely on the principle of removing unwanted solutes and water through a semipermeable membrane. This membrane is either biological (peritoneum) or artificial (hemodialysis or hemofiltration membranes), and each has advantages, disadvantages, and limitations.
