无创血液动力学监测在血液透析病人干体重中的应用

Noninvasive Hemodynamics as an Indicator for the Dry Weight in Hemodialysis

目的:透析过程中利用无创血液动力学监测透析患者的前负荷,观察无创血液动力学监测仪在透析患者干体重中的作用。方法:利用无创血液动力学监测仪观察正常人和血液透析患者透析前后的前负荷量,记录透析过程中血压、心率的变化,并结合患者的临床表现及化验检查。结果:无水负荷过重患者透析前后的前负荷量与正常人无明显区别,有明显水负荷的患者的前负荷明显高于正常人,P<0.05。结论:无创血液动力学可以准确的估计透析患者的干体重。

Objective： Using the technology of noninvasive hemodynamic monitorization to monitor the water load by which we could observe the effect of noninvasive hemodynamics for the dry weight in hemodialysis. Methods： Observing the TFC of normal people and hemodialysis patients before and after dialysis procession, the change of blood pressure and heart rate. At the same time we observe the clinic symptom and laboratory examination. Results： The TFC of the hemodialysis patients without over fluid load before and after dialysis procession has no difference with the normal people. But the TFC of the patients with over fluid load is higher than the normal people, P 〈 0.05 . Conclusions： Noninvasive hemodynamics can be use as an indicator to evaluate the dry weight of hemodialysis patients.
