血液透析患者家庭自测血压与透析日血压的相关性研究

The relationship between home blood pressure measurement and dialysis-center blood pressure in hemodialysis patients

目的调查家庭自测血压与血液透析中心测量血压的关联度,患者在透析中心测量的血压中,哪一个能更好反映非透析日血压的状态。方法有56名血液透析患者参与研究,分别采集患者家庭自测血压、上机前血压及上机后不同时间点血压情况,比较不同时间点血压测量值之间的相关性。结果上机后1h血压判定为高血压组、正常血压组与家庭自测血压判定为高血压组、正常血压组的符合率最高,分别为81.8%、61.8%。将患者按照家庭自测血压状态分为高血压组和正常血压组后,可见高血压组上机前30min的收缩压、舒张压与家庭自测收缩压、舒张压的差值最小,而正常血压组,上机前30min的收缩压、舒张压与家庭自测收缩压、舒张压的差值最大。结论上机后1h血压判定为高血压组、正常血压组与家庭自测血压判定为高血压组、正常血压组的符合率最高,可以通过上机后1h血压状态估计患者透析间期的血压情况。

Objective To investigate the relationship between the blood pressure measured at home and in dialysis-center in hemodialysis patients.Methods Fifty-six patient on hemodialysis participated in this study.Their blood pressure values measured at home,before and after the initiation of a dialysis session were compared.Results The patients were divided into hypertension group and controlled hypertension group according to the blood pressure measured at home.Blood pressure measured on dialysis for one hour matched the blood pressure at home with the agreement rate of 81.8％ and 61.8％ in hypertension group and controlled hypertension group,respectively.Conclusions The blood pressure measured on dialysis for one hour matched the normal blood pressure and hypertension measured at home,and can be used to estimate the blood pressure change during dialysis session.
