Blood Parameters in Human Fetuses with Congenital Malformations and Normal Karyotype

The acid-base balance (pH, pCO2, bicarbonate concentration) and the oxygenation level of the fetuses (pO2, SaO2) were evaluated on umbilical venous blood (UVB), taken by cordocentesis. At the same time, the glucose, lactate, free fatty acid, aceto-acetate, betahydroxybutyrate and cholesterol concentrations were measured, being essential biochemical constituents in relation to the nutritional status.
