Dialysate which is for renal failure is a class contains a variety of ionic and non-ionic substance
solution has a certain osmotic pressure, for rectal, peritoneal dialysis, or in
vitro, rid the body of metabolic wastes (such as urea); rid the body of excess
poisons or drugs; regulate body fluids The water - electrolyte balance and so
on, are generally used for patients with renal failure. Dialysis dialysate
metabolic waste can be taken away in the blood, regulating plasma electrolyte
imbalance and acid-base balance, so the dialysate composition whether it is
appropriate to improve uremic symptoms and correct complications is important,
so to take full account of the dialysate composition and content . In addition,
sometimes necessary to adjust the concentration of the dialysate certain
ingredients, such as increasing the sodium, calcium or potassium concentration
lowered to meet the clinical needs of the individual patient. Then the
components of blood dialysis solution, what does?
(1) Sodium: Sodium is the major extracellular cation, to maintain plasma
osmolality and volume plays an important role. In order to maintain sodium
balance in dialysis patients, sodium dialysate required value slightly lower
than the normal serum sodium concentration is generally 130 ~ 140mmol / l.
(2) Potassium: Potassium is the main cation of intracellular fluid, dialysate
potassium concentration is generally 0 ~ 4mmol / l, you can choose different
concentrations of potassium dialysate according to different needs. No potassium
dialysate (0 ~ 1mmol / l), mainly used arf no urine or high catabolism of
hyperkalemia in patients beginning dialysis or head 1 to 2 hours; low potassium
dialysate (2mmol / l), and more for every conventional dialysate (3 ~ 4mmol /
l), for pre-dialysis potassium normal maintenance dialysis or in patients taking
digitalis; high potassiu
(3) Calcium: calcium levels in hemodialysis patients most low, the calcium
reaches dialysis normal or slightly positive balance. Dialysate calcium content
should be between 1.5 ~ 1.75mmol / l.
(4) Magnesium: renal failure, renal failure patients often have
hypermagnesemia dialysate magnesium concentration is generally 0.6 ~ 1mmol / l,
slightly lower than normal plasma magnesium.
(5) Chlorine: chloride ions in the dialysate is substantially identical with
the extracellular fluid, is determined by the concentration of the cation and
sodium acetate, at a concentration of 96 ~ 110mmol / l.
