[Prognostic value of the early determination of plasma volume in arterial hypertension during pregnancy].
The authors have estimated the maternal plasma volume ine 243 patients by undertaking 282 calculations. The samples were taken often a fairly long time before the delivery, the mean being 4.05 weeks and the maximum being 16 weeks. The results were compared between normal pregnancies and those with hypertension that had no effect on the mother or fetus. The increase in the plasma volume was however significantly far less when the hypertension was severe or when there was intra-uterine growth retardation, either by itself or in association with hypertension. There is a positive correlation between the plasma volume and the fetal weight and thus a good index of normal growth can be worked out. Measuring the plasma volume, therefore, can be used as an early screening technique for severe hypertension with high risk for the fetus.
