DIALYSIS TREATMENT FOR KIDNEY DISEASE By Zachary Jacobson DIALYSIS TREATMENT FOR KIDNEY DISEASE By Zachary Jacobson

History First practiced on animals in early 1900’s Developed by Dr. Willem Kolff in History 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

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

Methods Dialysis requires surgery to develop access site 3 types: fistula, graft, catheter Filter Methods 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

How it Works (PD) Peritoneal Dialysis Creation of access site Permenant Peritoneal Catheter Dialysate How it Works (PD) 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

How it works (HD) Hemodialysis Blood filtered outside of body Dialyser Filters through synthetic How it works (HD) 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

Advantages/Disadventages PD vs. HD HD uses more predictable membrane PD is easier to use Advantages/Disadventages 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.

Limitations PD and HD do not replicate all kidney functions Access sites can move Limitations 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

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