2 types of dialysis: | hemodialysis and peritoneal dialysis |
Hemodialysis | filters waste products from the pt's blood; a shunt implanted in the pt's arm is connected to the artificial kidney machine and arterial blood flows thru the filters; the filters contain dialysate ( a solution made up of water and electrolytes) which removes excess fluids and waste from the blood; after these are removed, the blood is returned to the body thru a vein |
Peritoneal dialysis | the lining of the peritoneal cavity acts as the filter to remove waste from the blood; dialysate solution is run into the peritoneal cavity and the fluid is exchanged thru a catheter implanted in the adominal wall; this type is used for renal failure and certain types of poisoning |
