【摘要】 目的通过检测血液透析中血容量曲线与相应ΔBV值(血容量变化值)的变化,配合调整钠离子浓度,控制血液透析中低血压的发生,达到合适的干体重。方法20例维持性血液透析中易出现低血压患者按病情分为两组:A组(血液透析间期高血压患者)12例和B组(血液透析间期血压正常患者)8例。两组患者均采用常规血液透析和可调钠离子浓度透析。采用多光谱分光光度计连续实时测量红细胞压积、血红蛋白、血氧饱和度,计算ΔBV值;实时监测钠离子浓度曲线,并依据ΔBV值对其进行调整。观察两组患者血液透析中低血压的发生情况。结果A、B两组患者进行常规血液透析均出现低血压;A组常规血液透析模式发生低血压12例(占100%),A组钠及容量曲线模式发生低血压1例(占8.33%),两者相比,有显著性差异(P<0.05);B组常规血液透析模式发生低血压8例(占100%),B组钠及容量曲线模式发生低血压2例(占25%),两者相比,有显著性差异(P<0.05);A、B两组常规透析及可调钠离子浓度透析后患者血钠离子浓度变化不大(P>0.05)。结论通过监测血容量曲线的变化,及时调整超滤及透析液钠离子浓度,稳定了标准透析中易发生低血压的血液动力学因素,延迟了低血压发生的时间,降低了低血压的发生率。更多还原

【Abstract】 Objective Objective To investigate blood volume perseveration for patients suffering from uremia with profile.Methods Two groups of 20 patients suffering from uremia with conventional hemodialysis were chosen by the blood pressure during hemodialysis interphase.Every patient underwent with conventional hemodialysis treatment and sodium profile combined with ultrafitration profile 10 times alternatively. And then the blood volume changes(ΔBV),the blood plasma and clinical symptoms were observed during treatments.Results The blood pressure falling range evidently reduced(P<0.05),and the Na~+ chroma increasing range inapparent changed(P>0.05).Conclusion Sodium profile combined with ultrafiltration profile prevents the reduction of blood volume of hemodialysis patients evidently, reduces the possibility of profile complications. The sodium profile combined with ultrafitration profile is an effective medical treatment.更多还原
