应用斜线强化超滤对维持性血液透析患者心功能与血压节律的影响

目的研究斜线强化超滤模式对维持性血液透析（maintenance hemodialysis,MHD）患者心功能与血压节律的影响。方法将100例进行MHD患者按照随机分组的原则分成观察组与对照组,每组50例,其中观察组采取斜线强化超滤模式,对照组采取常规直线超滤模式,各进行透析2000例次,观察2组患者透析过程中心率、血压节律的改变以及低血压发生情况。结果 2组患者透析过程中心率、血压比较均无统计学差异（P〉0.05）;观察组发生低血压41例次（2.05%）,对照组发生低血压278例次（13.90%）,两组比较差异显著（÷2=22.321,P=0.000）。结论应用斜线强化超滤模式进行MHD,对患者心功能无明显影响,但能显著降低透析过程中低血压的发生率。

Application of diagonal reinforcement ultrafiltration on the maintenance hemodialysis patients cardiac function and blood pressure rhythm in effect

Objective To study the diagonal reinforcement ultrafiltration mode on maintenance hemodialysis patients cardiac function and the influence of blood pressure rhythm.Methods 100 cases of hemodialysis patients for support in accordance with the principle of randomized divided into observation group and control group,each group of 50 cases,including the observation group take diagonal reinforcement ultrafiltration mode,the control group take the conventional linear ultrafiltration mode,each for hemodialysis 2000 cases of times,observation two groups of patients dialysis process center rate,blood pressure and low blood pressure rhythm changes occur.Results two groups of patients dialysis process center rate,blood pressure comparison were no statistical difference（P0.05）;The observation group occur hypotension 41 cases of time（2.05%）,and 278 cases of control group occur hypotension times（13.90%）,two groups of comparisons significant difference（÷2=22.321,P=0.000）.Conclusion the application of diagonal reinforcement ultrafiltration model for blood dialysis,there was no significant effect on heart function of patients,but can significantly reduce the incidence of hypotension dialysis process.
