  • 1. Remove waste products Fluid control BP control RBC production Keeping bones healthy

2. We may feel sick, sleepy, confused or nauseous. (waste products) We will feel tired and pale. (RBC) We may have ankle swellings & start to feel breathless. (extra fluid) We may have bad breath & loss of appetite. (waste products) 3. PRESENTED BY ANU ISSAC 4. First form of dialysis practised by Romans. 1854- the term dialysis was used for the first time by Thomas Graham. 1913- first article on hemodialysis- Artificial kidney 1920s- first dialysis performed by George Hass 1948- first successful dialysis in Mount Sinai hospital by Willem Kolff 5. Dialysis is the movement of fluid and molecules across a semipermeable membrane from one compartment to another. Clinically, dialysis is a technique in which substances move from the blood through a semipermeable membrane and into a dialysis solution (dialysate) 6. Hemodialysis Peritoneal Dialysis 7. OSMOSIS 8. DIFFUSION 9. Ultrafiltration 10. 1. blood 6. dialysate 7. body 2. access 3. tx w/ heparin 4. dialyser 5. solute exchange 4-6 hours 11. Cleanses the blood of accumulated waste products Removes the by-products of protein metabolism (urea, creatinine & uric acid) Removes excessive fluids Maintains or restores the buffer system of the body Maintains or restores electrolyte levels 12. Removal of solutes and water from the blood across a semipermeable membrane 13. Selective filter for removing toxic or unwanted solutes from the blood 14. Rectangular cross section, parallel plate dialyser. 15. CIRCULAR CROSS SECTION; HOLLOW FIBER DIALYSER 16. Organic cellulose derivatives Synthetic membranes 17. DIALYSATE The fluid that is pumped through the dialyser on the opposite side of the semi permeable membrane to the patients blood. Correct the chemical composition of uremic blood to normal physiological levels. 18.

Filtration Activated carbon filters (adsorption) Water softners Reverse osmosis (RO) De ionization Ultraviolet light exposure 23. The removal of air The removal of any chemicals 24. PERMANENT VASCULAR ACCESS Arterio venous fistulas (AVFs) Arterio venous grafts (AVGs) Shunts 25. Advantages Disadvantages less danger of clotting and bleeding can be used indefinitely decreased incidence of infection no external dressing required freedom of movement cannot be used immediately after insertion venipuncture is required for dialysis infiltration of needles hematoma aneurysm in the fistula Arterial steal syndrome Congestive heart failure 26. Advantages Disadvantages less danger of clotting and bleeding can be used indefinitely decreased incidence of infection no external dressing required freedom of movement cannot be used immediately after insertion venipuncture is required for dialysis infiltration of needles hematoma aneurysm in the fistula Arterial steal syndrome Congestive heart failure 27. Access is formed by the surgical insertion of 2 silastic cannulas into an artery or vein in the forearm or leg to form an external blood path. 28. Advantages Disadvantages can be used immediately after insertion no venipuncture necessary for dialysis external danger of disconnecting or dislodging the shunt risk of hemorrhage, infection or clotting skin erosion around the catheter site 29.

Inflow (fill) 10 minutes Dwell ( equilibration) 20 minutes to 8 or more hours Drain - 15 to 30 minutes 43. Automated peritoneal dialysis (APD) Continuous ambulatory peritoneal dialysis (CAPD) 44. Continuous cycling peritoneal dialysis ( CCPD) Nocturnal intermittent peritoneal dialysis (NIPD) Intermittent peritoneal dialysis (IPD) Tidal peritoneal dialysis (TPD) 45. Requires a peritoneal cycling machine called a cycler Can be done as intermittent peritoneal dialysis, continuous cycling peritoneal dialysis, or nightly peritoneal dialysis 46. 1. The dialysate is instilled into the peritoneal cavity through an implant catheter attached to a transferline, which is attached to a bag of dialysate. 2. Once the fluid has been instilled completely into the peritoneal cavity, the empty bag and transferline are folded up and worn in a cloth pouch beneath the clothing. Thus, the patient is free to ambulate and resume his normal daily activities. 47. 3. When it is time to drain off the effluent, the bag is unfolded, placed on the floor and drainage is achieved by gravity. A new bag of dialysate is then attached to the transferline and the process is repeated. Usually the solution exchange procedure takes about 15 minutes. 48. o FREEDOM FROM DIALYSIS MACHINE o CONTROL OVER DAILY ACTIVITIES o OPPURTUNITIES TO AVOID DIETARY RESTRICTIONS 49.

Pain/discomfort related to dialysis process. Altered thought process related to dialysis diaequilibrium syndrome Ineffective individual/ family coping related to diagnosis of chronic illness Noncompliance to prescribed treatment regimen 56. a)Imbalanced nutrition, less than body requirement related to protein loss in the dialysate b)Risk for infection realted to presence of peritoneal dialysis catheter. c) risk for imbalanced fluid volume related to hypertonicity of the dialysate or inadequate exchange. d) activity intolerance to related to fatigue e) risk for complications related to the disease condition and dialysis procedure 57. 1) TUCKER MARTIN SUSAN, CANOBBIO.
