Dialysis
The kidneys are important organ in the body. It helps regulate extracellular fluid and excrete waste products from the body. The kidneys also function to control blood pressure, produce erythropoietin, activate vitamin D, and regulate acid-base balance. When the kidneys fail to function, or work as they should, dialysis is needed. Dialysis restores internal homeostasis by osmosis, diffusion, and ultrafiltration. It can sustain life for people who have acute and chronic renal failure. There are two different types of dialysis, hemodialysis and peritoneal dialysis. Hemodialysis is a dialysis that uses an artificial membrane as the semipermeable membrane through which the patient’s blood circulates. The access for hemodialysis is accomplished by

Depending on the dialysis treatment used, protein and other essential electrolytes are either removed or retained. It is essential to monitor laboratory values and to perform proper assessments to assure the patient is receiving the best care possible. Peritoneal dialysis tends to extract protein. Knowing this, a patient who is on peritoneal dialysis would be on a high protein diet to compensate for this loss. Potassium is usually individualized depending on laboratory values and the extent of the disease. A patient undergoing hemodialysis should maintain a daily allowance intake of two to three grams per day, whereas a patient using peritoneal dialysis is not restricted of potassium. Sodium level should be maintained and monitored throughout dialysis. While sodium intake is individualized, considerations must be taken to limit high sodium diets such as processed foods, canned foods, and cured meats. When the kidney function deteriorates, phosphorus is retained causing hyperphosphatemia. Since phosphate is found in many protein food sources, phosphate binders are essential to control
