可调钠透析液中离子浓度与电导度关系的研究与探讨
Research and Discussion of the Relationship Between the Ion Concentration in the Variable Sodium Dialysis and the Conductivity
摘要
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.关键词
