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.
An extracorporeal procedure is a medical procedure which is performed outside the body. Extracorporeal devices are the artificial organs that remain outside the body while treating a patient. Extracorporeal devices are useful in hemodialysis and cardiac surgery .
Liver dialysis has shown promise for patients with hepatorenal syndrome. It is similar to hemodialysis and based on the same principles, but hemodialysis does not remove toxins bound to albumin that accumulate in liver failure. Like a bioartificial liver device, it is a form of artificial extracorporeal liver support. [45] [46]
Hemoperfusion or hæmoperfusion (see spelling differences) is a method of filtering the blood extracorporeally (that is, outside the body) to remove a toxin.As with other extracorporeal methods, such as hemodialysis (HD), hemofiltration (HF), and hemodiafiltration (HDF), the blood travels from the patient into a machine, gets filtered, and then travels back into the patient, typically by ...
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 ...
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 ...
Kidney dialysis is the process of removing water, solutes and toxins from the blood of individuals with compromised kidney function, primary types of which are: Hemodialysis; Peritoneal dialysis; Hemofiltration; Liver dialysis, a detoxification treatment for liver failure. Dialysis, a genus of insects in the family Xylophagidae
It is thus an extracorporeal therapy, a medical procedure performed outside the body. [1] Three general types of plasmapheresis can be distinguished: Autologous, removing blood plasma, treating it in some way, and returning it to the same person, as a therapy. Exchange, a patient's blood plasma is removed, while blood products are given in ...
