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.
从健康孕妇、血压不稳定的孕妇以及患有严重妊娠中毒症（先兆子痫）的孕妇的母体耳部、子宫颈和胎儿处同时采集微量血样。对血氧分压（po2）、酸碱度（pH）、碱剩余（BE）和二氧化碳分压（pco2）进行了研究。胎儿未显示出窒息迹象。患有妊娠中毒症的女性与其胎儿之间的BE值差异明显大于健康妊娠情况。在血氧分压、酸碱度和二氧化碳分压值方面，健康孕妇组与患有妊娠中毒症的孕妇组之间未发现差异。这支持了以下观点：在母亲患有妊娠中毒症时，胎儿有代谢性酸中毒的倾向，这显然使胎儿在发生急性窒息时比健康母亲的胎儿处境更糟。在研究时，血压不稳定的孕妇的胎儿的血氧分压低于健康孕妇的胎儿。
