摘要：Hypertension is the most frequent hemo-dynamic disorder in patients treated with hemodialysis therapy. Over-hydration is one of the most important risk factors leading to arterial hypertension. The assessment of over-hydration and ipso facto, correct evaluation of „dry weight” is an essential part of therapy. Electrical bioimpedance analysis is a tool used for estimating the level of hydration.Aim. The aim of this study was to assess optimal dry weight in 12 dialyzed patients with arterial hypertension over a period of six months; Study evaluations were performed every two weeks for the first three months and once a month for the final three months of our study. The whole body bioimpedance analysis and the Wizemann Clinical Scale were used in the study.Material and methods.Our results demonstrated a significant correlation between systolic blood pressure value and the size of extracellular space before hemodialysis in the entire group of patients (r=0.55; p=0.001). In the group of patients in which we were able to reduce blood pressure by obtaining optimal dry weight (the whole body electrical bioimpedance and the Wizemann Clinical Scale were used to estimate ECW sizes) to a level allowing termination of their hypotensive medicines, there was also observed a statistically significant correlation between the systolic blood pressure and the size of ECW before hemodialysis (r=0.40; p=0.006).Conclusions. The size of extracellular space calculated with the use of the whole body electrical bioimpedance analysis before dialysis corresponded with the Wizemann Clinical Scale and was a valuable tool in the evaluation of hydration levels. Obtaining the correct body mass (optimal dry weight) resulted in reduction or total termination of hypertensive therapy.
