含糖透析液对维持性血液透析患者心率变异性和血压的影响

目的评价在维持性血液透析患者中应用含糖透析液和无糖透析液对心率变异性(heart rate variability,HRV)、血压和血糖的影响。方法纳入10名稳定的非糖尿病的慢性血液透析患者。每个患者进行2次无糖透析液透析,2次含糖透析液透析,每次透析4h,形成无糖透析液组和含糖透析液组,每次透析过程中均对患者进行HRV连续监测,在透析0、1、2、3、4h进行血压、血糖的监测。观察含糖透析液对HRV指标和血压、血糖的影响。统计方法采用重复测量的方差分析。结果无糖透析液组和含糖透析液组透析时的心率和血压的基线值可比。在透析过程中,无糖透析液组的收缩压较含糖透析液组时明显升高,第4h的平均收缩压差别有统计学意义(F=1718.10,P0.05)。无糖透析液组发生3人次低血糖,含糖透析液组没有出现低血糖。无糖透析液组标准化低频功率较含糖透析液组显著升高(t=4.31,P0.05),而标准化高频功率较含糖透析液组显著降低(t=-3.71,P0.05)。无糖透析液组低频功率/高频功率(LF/HF)较含糖透析液组偏高,但差异无统计学意义(t=0.66,P0.05)。结论透析过程中使用无糖透析液可能引起交感神经的过度激活,继而引起高血压。血液透析患者使用含糖透析液可能有益。

Influence of glucose containing dialysate on heart rate variability and blood pressure in maintenance hemodialysis patients

Objective Heart rate variability (HRV) is related to autonomic nervous system disturbance.The aim of current study was to evaluate whether dialysates with glucose (DG) and dialysate without glucose (DNG) affect HRV,blood pressure and blood glucose during hemodialysis (HD) sessions.Methods Ten stable nondiabetic chronic HD patients were enrolled in this study.Each patient underwent 4 HD sessions,of which twice used DG and twice used DNG.Patients were dialyzed for 4 hours per session.During every dialysis ses...
