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.
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 ...
Aluminium toxicity in people on dialysis is a problem for people on haemodialysis. Aluminium is often found in unfiltered water used to prepare dialysate . The dialysis process does not efficiently remove excess aluminium from the body, so it may build up over time. [ 2 ]
Treatment of chronic failure may include hemodialysis, peritoneal dialysis, or a kidney transplant. [2] Hemodialysis uses a machine to filter the blood outside the body. [2] In peritoneal dialysis specific fluid is placed into the abdominal cavity and then drained, with this process being repeated multiple times per day. [2]
Vitamin and mineral management for dialysis patients is a required treatment for people undergoing dialysis because during end-stage kidney disease and dialysis the kidneys are functioning at less than 15% of normal levels. [1] As a consequence, certain vitamin and mineral restrictions and supplementations are needed. [2]
Nephrology (from Ancient Greek nephros 'kidney' and -logy 'the study of') is a specialty for both adult internal medicine and pediatric medicine that concerns the study of the kidneys, specifically normal kidney function (renal physiology) and kidney disease (renal pathophysiology), the preservation of kidney health, and the treatment of kidney disease, from diet and medication to renal ...
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.
