Summary
The viscosity at low shear rate of whole blood, plasma and serum, the haematocrit, plasma fibrinogen, plasma proteins, and IgM were measured in maternal and cord blood immediately following delivery. The whole blood viscosity in maternal blood (mean 19.96±3.74 centipoise or c/p) was similar to cord blood viscosity (mean 19.44±4.28 c/p). The mean haematocrit in maternal blood (0.385±0.026) was significantly lower than the cord haematocrit (0.488±0.039). Mean plasma viscosity (1.86±0.47 c/p) and plasma fibrinogen (4.25±0.75 g/litre) in maternal blood were significantly higher than cord plasma viscosity (1.12±0.19 c/p) and cord plasma fibrinogen (1.81±0.61 g/l). Mean serum viscosity (1.22±0.28 c/p) and mean IgM levels (2.38±0.36 g/l) in maternal blood were significantly higher than cord serum viscosity (0.92±0.15 c/p) and cord IgM (0.48±0.06 g/l). The low levels of IgM and fibrinogen may protect the fetus from the increased viscosity that could be expected in association with a high haematocrit.
