Abstract
The authors performed bioimpedance analysis and Cardio Tens (24-h ABPM and ECG) monitoring in 66 patients (28 males, 38 females) treated in the chronic haemodialysis programme. They investigated the correlations between the body weights before, during and after dialysis, the changes of the water compartments and fat body weight, and the recorded values of blood pressure and ECG alterations. On the basis of the measurements by this non-invasive method it is concluded that, as a result of dialysis and ultrafiltration, the total body weight and total body water are decreasing in a greater extent in men than in women. By gradually decreasing the body weight, the optimal dry weight could be attained, which resulted in the reduction of blood pressure or even normotension. In the course of dialysis the values of bioimpedance and bioreactance increase. The intradialytic hypotensive indispositions were accompanied by a significant reduction of bioreactance (n=16). The BMI, total body weight and total body water hyperlipidaemic, hypalbuminic patients with treatment-resistant hypertension are considerably larger than those of the patients with normal blood pressure (p<0.01). During Cardio Tens monitoring 53% of the patients proved to be dippers, 47% of whom had ST depression, while in 73% of the non-dippers ischaemic alterations were encountered together with high hyperbaric impact values. The total body weights and total water compartments of patients returning to dialysis with an excess body weight of more than 3.5 kg were significantly larger than of patients who were cooperative and had no oedemas. In the last hour of dialysis and during the following few hours, arrhythmias and ST depressions of the cardiovascularly instable patients appeared more frequently. The total water compartments of these patients are significantly larger than normotensive, normolipaemic patients with appropriate serum albumin concentrations. The importance of the BIA and Cardio Tens monitoring in determining the optimal dry body weight and improving the cardiovascular condition of the patients is emphasized.
