Six patients on maintenance hemodialysis were investigated by direct determination of hemodynamic changes induced by UF. Our results show: 1. Despite a significant fall in ECF and PV, the PV/IF ratio was unchanged indicating absence of major fluid shifts between intravascular and extravascular compartments. 2. The rise in CPV/TBV ratio observed indicates central redistribution of intravascular fluid suggesting venoconstriction. 3. CPV and hence CO was maintained so that a stable MAP resulted.
通过直接测定超滤诱导的血流动力学变化，对6例维持性血液透析患者进行了研究。我们的结果显示：1. 尽管细胞外液（ECF）和血浆容量（PV）显著下降，但PV/IF比值未变，表明血管内和血管外间隙之间没有重大的液体转移。2. 观察到的中心血容量（CPV）/总体液量（TBV）比值升高表明血管内液体向中心重新分布，提示静脉收缩。3. CPV以及因此的心输出量（CO）得以维持，从而导致平均动脉压（MAP）稳定。
