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]
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.
Hemodialysis is the choice of renal replacement therapy for patients who need dialysis acutely, and for many patients as maintenance therapy. It provides excellent, rapid clearance of solutes. [2] A nephrologist (a medical kidney specialist) decides when hemodialysis is needed and the various parameters for a dialysis treatment. These include ...
The Government of China provides the funding for dialysis treatment. There is a challenge to reach everyone who needs dialysis treatment because of the unequal distribution of health care resources and dialysis centers. [45] There are 395,121 individuals who receive hemodialysis or peritoneal dialysis in China per year.
In 1972 the United States Congress passed legislation authorizing the End Stage Renal Disease Program (ESRD) under Medicare. Section 299I of Public Law 92-603, passed on October 30, 1972, extended Medicare coverage to Americans if they had stage five chronic kidney disease (CKD) and were otherwise qualified under Medicare's work history ...

Blood containing excess salt and water is withdrawn from a patient using peripheral or central venous catheters and passed through a special filter. Using a form of ultrafiltration, the filter separates the excess salt and water from the blood and the blood is returned to the patient while the fluid is collected in a bag for later disposal.
Infection is the cause of death in about one third of people with renal transplants, and pneumonias account for 50% of the patient deaths from infection. [80] Delayed graft function is defined as the need for hemodialysis within 1 week of kidney transplant and is the result of excessive perfusion related injury after transplant. [79]
