Before implementing continuous renal replacement therapy (CRRT), acute renal failure (ARF) in critically ill, multiple organ failure patients was managed by intermittent hemodialysis and the mortality rate was very high. [4] Hemodialysis is effective in clearance and ultrafiltration, but it has deleterious effects on hemodynamic stability. [5]
Dialysis disequilibrium syndrome is a reason why hemodialysis initiation should be done gradually, i.e. it is a reason why the first few dialysis sessions are shorter and less aggressive than the typical dialysis treatment for end-stage renal disease patients. [citation needed]
Hemofiltration is sometimes used in combination with hemodialysis, when it is termed hemodiafiltration. Blood is pumped through the blood compartment of a high flux dialyzer, and a high rate of ultrafiltration is used, so there is a high rate of movement of water and solutes from blood to dialysate that must be replaced by substitution fluid that is infused directly into the blood line.
Schematic of semipermeable membrane during hemodialysis, where blood is red, dialysing fluid is blue, and the membrane is yellow. Kidney dialysis (from Greek διάλυσις, dialysis, 'dissolution'; from διά, dia, 'through', and λύσις, lysis, 'loosening or splitting') is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer ...
Hemodialysis, also spelled haemodialysis, or simply dialysis, is a process of filtering the blood of a person whose kidneys are not working normally. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure.
The term "non-dialysis-dependent chronic kidney disease" (NDD-CKD) is a designation used to encompass the status of those persons with an established CKD who do not yet require the life-supporting treatments for kidney failure known as kidney replacement therapy (RRT, including maintenance dialysis or kidney transplantation).
Acute kidney injury (AKI), previously called acute renal failure (ARF), [12] [13] is a rapidly progressive loss of renal function, [14] generally characterized by oliguria (decreased urine production, quantified as less than 400 mL per day in adults, [15] less than 0.5 mL/kg/h in children or less than 1 mL/kg/h in infants); and fluid and ...
Supportive care, dialysis, steroids, blood transfusions, plasmapheresis [2] [1] Prognosis <25% long-term kidney problems, which for some of these, could include chronic kidney dysfunction or even failure (which could ultimately need dialysis or transplantation to treat); [ 1 ] 5% risk of death during the illness in developed countries with ...
