Aims and Objectives Aims On the completion of the seminar students gain the knowledge regarding hemodialysis and peritoneal dialysis and will utilize this knowledge with a positive attitude. Specific Objectives The group will able to; * Define dialysis * Describe the history of dialysis * Explain the principles of dialysis * Enumerate the indication of dialysis * Explain details about hemodialysis * Describe details about peritoneal dialysis * List down the Psychosocial Issues In ESRD Patients * Dietary Management Dialysis Patient * Nursing Responsibilities Introduction The introduction of dialysis as a lifesaving treatment for kidney failure was not the result for any large scale research…show more content…
In Kidney failure cases urea, creatine, uric acids and electrolytes move from the blood to the dialysate with the net effect of lowering their concentration in the blood. RBC s WBC s and plasma proteins are too large to diffuse through the pores of the membrane. Hemodialysis patient are exposed to 120 to 130 L of water during each dialysis treatment. Small molecular weight substances can pass from the dialysate in to patient’s blood. So the purity of water used for dialysis is monitored and controlled. * Osmosis: Osmosis is the movement of fluid from an area of lesser concentration to an area of greater concentration of solutes. Glucose is added to the dialysate and creates an osmotic gradient across the membrane, pulling excess fluid from the blood. * Ultra filtration: Ultra filtration results when there is an osmotic gradient or pressure gradient across the membrane. In PD excess fluid is removed by increasing the osmolality of the dialysate with the addition of glucose. In HD , the gradient is created by increasing pressure in the blood compartment(positive pressure)t ore decreasing pressure in the dialysate compartment(negative pressure). Extracellular fluid moves in to the dialysate because of the pressure gradient. The excess fluid is removed by creating a pressure differential between the blood and the dialysate solution.
