Relative Blood Volume in Patients on Program Hemodialysis
Abstract
Preservation of the intravascular volume is the first choice measure for the prevention of intradialysis hypotension. At present there are devices that allow a continuous monitoring of relative blood volume (RBV) during haemodialysis (HD). The aims of this research were to check data validity of two devices: BVM (Fresenius MC, Germany) and Crit-Line (In-Line Diagnostics Corporation, USA) and to investigate the influence of different dialysis modes on RBV. The coincidence of reading of two monitors and laboratory values of Hb and Ht were assessed during 30 HD sessions in 15 patients. In patients with hyperhydratation RBV curves were monotone and maximum drops of RBV (DRBV) were minor. In all cases relation DRBV/ultrafiltration volume (UF) did not exceed 2,5%/l. In 32 stable HD patients consecutive uses of 5 different UF and Na+ profiles did not decrease DRBV. Intradialysis hypotension was observed in cases of rapid RBV fall during first hour of HD (6,72 ± 0,86% for HD with hypotension vs 3,86 ± 1,02% in general, р < 0,05) and when DRBV/UF was high (>6%/L).
