The author aimed to compared and simultaneously interpret results from cardiotocographic, ultrasound and hormonal studies and to establish objective criteria, showing the degree of antenatal risk for the fetus. She investigated 176 pregnant women with EPH--gestosis, 136 women with chronologically prolonged pregnancy and 50 healthy pregnant women as a control group. Non stress test (NST, functional oxytocin test, quantitative and semiquantitative evaluation of cardiac frequency of the fetus (CFF) were made. Placental structure was examined by an echograph, as well as the amount of amniotic fluid. Fetal biometry was made as well. Total estrogens (TE) were determined in 24-hour diuresis. It was established that the normal curve of NST was a sign of fetal well-being, but that curve combined with deceleration, together with low values of TE, were criteria for reduced compensatory possibilities of the fetus. NST with decelerations in Braxton Hicks contractions, even part greater than 80% and "terminal" or sharply falling values of TE were signs impending fetal death.
作者旨在比较并同时解读来自胎心监护、超声和激素研究的结果，并建立客观标准，以显示胎儿产前风险的程度。她研究了176例患有妊娠高血压综合征的孕妇、136例过期妊娠的孕妇以及50例健康孕妇作为对照组。进行了无应激试验（NST）、缩宫素功能试验、胎儿心率（CFF）的定量和半定量评估。通过超声检查胎盘结构以及羊水量。还进行了胎儿生物测量。测定了24小时尿液中的总雌激素（TE）。结果表明，NST的正常曲线是胎儿健康的标志，但该曲线伴有减速，同时TE值较低，则是胎儿代偿能力降低的标准。在Braxton Hicks宫缩中出现减速的NST，即使部分大于80%，以及TE的“终末”或急剧下降值，都是胎儿即将死亡的迹象。
