Hemodialysis therapy refers to the use of hemodialysis or peritoneal dialysis to save the lives of patients, prolong the life of uremic patients with excessive. With the increase of various diseases, resulting in patients with end-stage renal disease is increasing year by year. The maintenance hemodialysis patients not only includes chronic nephritis and uremia, such as diabetes, common causes of hemodialysis for uremic patients is due to hypertension.
Dietary therapy for hemodialysis patients
Protein: normal protein diet: 1.0-1.2 g / kg / day, because amino acids may be lost in the dialysis fluid, and the decomposition increased, adequate intake of calories: 30-35 kcal / kg / day, suggest poor appetite, malnutrition, inadequate dialysis patients with application.
Water: evaluation of hemodialysis water clear accurate assessment, determine the appropriate dry weight: water load, body weight changes, blood pressure, heart function, urine volume, blood volume monitoring, water removal, no symptomatic hypotension should be evaluated and adjusted monthly. Dry weight interdialytic weight. The appropriate increase of < dry weight 3%.
Phosphorus: phosphorus intake and protein intake is closely related to P: 800-1000mg/d, but will affect the nutritional status of hemodialysis patients, low phosphorus and low potassium milk as currently recommended food. Each dialysis can remove 800mg phosphorus, because extracellular phosphorus accounted for only 1% of total body, increased phosphorus redistribution rebound after appearing, just one had decreased, can't really control hyperphosphatemia. It is necessary to use phosphate binders.
Dialysis is still widely used in renal replacement therapy. Although it can improve some symptoms of uremia, prolong the survival time, but can not replace the normal kidney dialysis all the complex metabolic and endocrine function, and because hemodialysis can only remove all kinds of water soluble small molecular substances, such as urea, nitrogen, muscle, and anhydride. So patients after dialysis repeatedly for a long time, possible series of hemodialysis complications.
