Renal replacement therapy includes dialysis (hemodialysis or peritoneal dialysis), hemofiltration, and hemodiafiltration, which are various ways of filtration of blood with or without machines. Renal replacement therapy also includes kidney transplantation , which is the ultimate form of replacement in that the old kidney is replaced by a donor ...
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.
Over 26 million American adults have kidney disease and most are not aware of it. More than 661,000 of them have kidney failure and 468,000 are on dialysis. The large population of individuals with kidney failure drives continuing advancements in the technology of artificial kidneys so that more people can have access to treatments. [8]
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.
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 ...
Kidney transplantation is a life-extending procedure. [87] The typical patient will live 10 to 15 years longer with a kidney transplant than if kept on dialysis. [88] The increase in longevity is greater for younger patients, but even 75-year-old recipients (the oldest group for which there is data) gain an average four more years of life.
Home hemodialysis (HHD) is the provision of hemodialysis to purify the blood of a person whose kidneys are not working normally, in their own home. One advantage to doing dialysis at home is that it can be done more frequently and slowly, which reduces the "washed out" feeling and other symptoms caused by rapid ultrafiltration, and it can often be done at night, while the person is sleeping.
Can be used to compare any dialysis schedule (i.e. nocturnal home hemodialysis vs. daily hemodialysis vs. conventional hemodialysis) Applicable to peritoneal dialysis. Can be applied to patients with residual renal function; it is possible to demonstrate that C o is a function of the residual kidney function and the "cleaning" provided by dialysis.
