Acid-base relationship between mother and fetus in gestosis (pre-eclampsia) and in pregnant women with a labile blood pressure.
Simultaneous blood microsamples were taken from the maternal ear and uterine cervix and the fetus of healthy pregnant women, those with labile hypertension, and those with severe gestosis (pre-eclampsia). The po2, pH, BE and pco2 were studied. The fetuses showed no signs of asphyxia. The differences in BE values between the women withe gestosis and their fetuses were significantly greater than in the cases of healthy pregnancy. No differences were seen between healthy and gestotic gravida groups in po2, pH and pco2 values. This favours the opinion that in gestosis of the mother the fetus has a tendency to metabolic acidosis, which apparently places it in a poorer position than the fetuses of healthy mothers, should acute asphyxia occur. At the time of study the po2 of the fetuses of gravidas with a labile blood pressure was lower than that of fetuses of healthy gravidas.
