Dialysis

  1. 1. DialysisBy Dr yogendra pandey
  2. 2. Introduction• In medicine, dialysis is a process for removing waste and excess water from the blood, and is used primarily to provide an artificial replacement for lost kidney function in people with renal failure.
  3. 3. introduction• Dialysis may be used for those with an acute disturbance in kidney function (acute kidney injury, previously acute renal failure), or progressive but chronically worsening kidney function–a state known as chronic kidney disease stage 5 (previously chronic renal failure or end-stage renal disease). The latter form may develop over months or years, but in contrast to acute kidney injury is not usually reversible, and dialysis is regarded as a "holding measure" until a renal transplant can be performed, or sometimes as the only supportive measure in those for whom a transplant would be inappropriate
  4. 4. Layout and flow of patient in a dialysis center
  5. 5. Dos and don’ts of a dialysis patient• Diet:-• Increase protein intake• Decrease potassium, phosphate intake• Limit fluids.• Medication:-• Avoid morphine and codeine.• Reduce doses of SSRIs (e.g., sertraline)• Avoid vitamin A supplements (fat soluble vitamins• not removed by dialysis)
  6. 6. Dos and don’ts• Associated Risks & Co morbidities :- anemia renal osteodystrophy pruritus arrhythmia amyloidosis insomnia (due to aching in legs) cardiovascular disease infection at venous access site peritonitis (from peritoneal dialysis)
  7. 7. Dos and don’ts• Preventive care :-1)Monitor potassium levels.2)Keep immunizations up to date, particularly in patients who may be candidates for transplantation.3)Assess/treat patient for depression/anxiety (which can arise when faced with dialysis).4)Testing for renal osteodystrophy and follow-up if results abnormal.5)Control BP and lipid levels.
  8. 8. Average length of stay• The average length of stay of a dialysis patient varies from 3 days to 8 days, that is more than a week in certain special cases if some additional complications are involved .
