[Study of parameters of central hemodynamics in patients during hemodialysis].

The article discusses the results of study of the cardiac output (CO) and circulation blood volume (CBV) in patients at the beginning and end of hemodialysis. The dynamics of changes of these parameters during hemodialysis was studied in 31 patients (42 sessions). The CO and CBV reduced significantly. In a group of 10 patients who felt worse, the CO reduced by more than 30 per cent in 7, the CBV diminished by 25 and 30 per cent in 2, and CBV and CO reduced by more than 30 per cent in 1 patient in relation to the initial level. The CO and CBV were measured by means of the method of dilution of electroimpedance indicators.
