WebTraditional dialysis is an alternative buffer exchange technique; however, it has several drawbacks: It relies on slow diffusion and difficult-to-handle dialysis tubing or cassettes. In many cases, during the course of dialysis, the volume in the dialysis tubing increases as a consequence of osmosis, further diluting the sample and requiring a ... Web• The use of bicarbonate dialysate as the buffer during routine dialysis is growing. This discussion reviews several of the comparative trials in which bicarbonate and acetate buffers have been tested. Effects of the two buffers on BP, cardiac function, and pulmonary performance are discussed. Costs of the two systems are also compared.

WebDialysate Buffer Bicarbonate is now the principal buffer used in dialysate. Producing bicarbonate dialysate requires a specifically designed system that mixes a bicarbonate concentrate and an acid concentrate with purified water. The acid concentrate contains a small amount of either lactic or acetic acid and all the calcium and magnesium. WebDialysate solution or dialyzing fluid is a nonsterile aqueous electrolyte solution that is similar to the normal levels of electrolytes (Table 13.1) found in extracellular fluid with the exception of the buffer bicarbonate and potassium.
