Isolated ultrafiltration (UF) has been shown to preserve plasma volume (PV) by means of a high plasma refilling rate, mediated by a rapid rise in oncotic pressure. This mechanism contributes to the good tolerance of sequential ultrafiltration-hemodialysis (SUH). This study compared PV changes induced by SUH and sequential hemodialysis-ultrafiltration (SHU). Seven dialysis patients underwent two sets of SUH and SHU, in which 2 h of UF (approximately equal to 3L) respectively preceded or followed 2 h of no-weight-change hemodialysis (ISO HD). VEM (volume of extravascular mobilization), VEM/VUF (percent of plasma refilling rate) and delta PV were calculated by mathematical formulas. Results showed: 1) a high VEM/VUF during the UF period, either before or after ISO HD: 80 and 77% respectively; 2) a significant increase in PV during ISO HD after UF, compared to ISO HD before UF: + 229 ml and + 43 ml, P less than 0.05; 3) VEM/VUF significantly higher during SUH than during SHU: 87 and 80%, P less than 0.01. In conclusion, the decrease in PV was lower in SUH than in SHU (11 vs. 19%, P less than 0.001) because the plasma refilling persisted through the ISO HD period.

D014511	Uremia	A clinical syndrome associated with the retention of renal waste products or uremic toxins in the blood. It is usually the result of RENAL INSUFFICIENCY. Most uremic toxins are end products of protein or nitrogen CATABOLISM, such as UREA or CREATININE. Severe uremia can lead to multiple organ dysfunctions with a constellation of symptoms.	Uremias
