73 case histories of induction of labour under epidural anaesthesia have been studied very thoroughly from the different parameters of the uterine contractions as well as the fetal heart rate and the acid base balance of the fetus. From this study it is clear that the basal tone, the intensity and the frequency of contractions and the activity of the uterus are increased in comparison with different studies of normal labour. This increase however is within physiological limits and does not change in any marked way the cardiac rhythm nor the acid base balance of the fetus. The Apgar score at birth is equal to or above 8 in 89 p. 100 of cases at 1 minute and in 100 p. 100 of cases at 5 minutes. Finally, in the last phases of the labour dilatation is quicker than in normal delivery. It follows therefore that maternal comfort has not been bought at the expense of the fetus.
我们对73例硬膜外麻醉下引产的病例进行了深入研究，涉及子宫收缩的不同参数、胎儿心率以及胎儿的酸碱平衡。从这项研究中可以清楚地看出，与正常分娩的不同研究相比，子宫的基础张力、收缩强度和频率以及子宫活动均有所增加。然而，这种增加在生理范围内，并未以任何显著方式改变胎儿的心律或酸碱平衡。出生时1分钟的阿氏评分在89%的病例中等于或高于8分，5分钟时在100%的病例中等于或高于8分。最后，在分娩的最后阶段，宫口扩张比正常分娩更快。因此可以得出结论，并未以牺牲胎儿为代价来换取产妇的舒适。
