Abstract：Objective This paper aimed to provide evidence for variable sodium dialysis in clinical
application based on studying the change of the hemodialysis’ ions in sodium profile. Methods 42
hemodialysis machine were randomly selected from our blood dialysis room. 14.30, 15.00 and 13.60
ms/cm were separately chosen as a conductivity of benchmark configuration, high configuration and
lower configuration, and let the machine stably run for 30 minutes. Physical and chemical analysis was
conducted on these samples getting from the dialyzer interface. Meanwhile, the sodium ion concentration,
pH value and bicarbonate ions concentration, and so on, were also recorded. Results The conductivity was
increased to 1.241 mmol/L from benchmark configuration to higher configuration sodium ion concentration.
The conductivity was decreased to 0.675 mmol/L from benchmark configuration to lower configuration
sodium ion concentration. The pH and sodium ions presented negative correlation. The concentration HCO3
-
and the total carbon dioxide CO2 (ctCO2) had undergone corresponding changes. But their changes were
all small, and all failed to meet the acid and alkali poisoning density. Conclusion Regulation of the
conductivity can change the concentration of sodium ions in the blood dialysis fluid, which can also
ensure not to change the pH, the concentration of HCO3
- and ctCO2.
