[Pregnancy-induced hypertension: maternal and fetal hemodynamics]

With hypervolemia, hemoconcentration, high vascular resistance and hypertension the SIH offers opposite changes as the physiological pregnancy. The absence of a decrease in hematocrit and MAP is as yet not used as early screening possibility. Doppler flow measurements allow a detection of a fetal brain sparing effect which seems to be a typical answer to placental insufficiency. According to the till published results the hypervolemic hemodilution is of advantage for the mother and the fetus. With Doppler flow measurements we have a new method to verify therapeutic conceptions for the SIH.
