1 By Zachary Jacobson

2  First practiced on animals in early 1900’s  Developed by Dr. Willem Kolff in 1943  First successful treatment administered in 1945  In 1950’s Dr. Belding Scribner uses Teflon tubing  Scribner heralded as father of bioethics  Scribner starts first outpatient facility in 1962

3  Function of Kidneys  Nephrons, glomeruli and waste tubules  Hormone secretion support homeostasis  Causes of Chronic Kidney Disease/Failure  Hypertension  Diabetes mellitus (3 types)  Diagnosing KidneyDisease/Failure  Elevated proteins and/or blood in urine  Function of Dialysis  Filter waste and excess fluid from blood

4  Dialysis requires surgery to develop access site  3 types: fistula, graft, catheter  Filter Membrane  Semi-permeable quality allows only smaller materials(i.e. waste) to diffuse across  Larger waste products and excess fluid require ultrafiltration  Dialysate  Composed of sterile water, electrolytes/chemicals and dextrose  Dextrose concentration determines osmotic pressure in PD exchange

5  Peritoneal Dialysis  Creation of access site  Permenant Peritoneal Catheter  Dialysate drawn into abdominal cavity  Peritoneum acts as filter  Waste stored in dialysate  Dextrose level determines ultrafiltration rate  2 types: CAPD, CCPD  Dialysate drained from cavity

6  Hemodialysis  Blood filtered outside of body  Dialyser  Filters through synthetic membrane  Thousands of thin hollow fibers  Countercurrent ultrafiltration  Different types of filters  Dialysis Machine  Monitors time, temp, pressure  Blood returned to body through access

7  PD vs. HD  HD uses more predictable membrane  PD is easier to use and more convenient  PD less likely to cause Hypotension  PD may cause trouble breathing  Dialysis patients require special diet and medication to replace hormonal function.

8  PD and HD do not replicate all kidney functions  Access sites can move or become infected  Limited movement  Body image  Time per treatment  Blood clotting  Expensive without health coverage

9  Shorter Dialysis Time  Increased Efficiency in Filtration  Increased Portability  Recycling of Dialysate  Simultaneous monitoring and introduction of synthetic hormones
