Elective induction was practised in 1875 of 10 537 deliveries (17.8%). Duration of delivery was, if anything, shortened after elective induction, compared with spontaneous delivery. There was no evidence of soft-tissue dystocias after elective induction. The Apgar score was 8-10 in 95.7% of children born after elective induction. pH of umbilical-artery blood in 95.7% of children after elective induction was greater than or equal to 7.2. There was a striking increase in the incidence of occiput posterior position with elective induction (2.7% of cases). The incidence of operative vaginal delivery was as frequent after elective as after all other forms of delivery. The incidence of section was 4.7% after elective induction, 11.5% in the entire series, intra-uterine asphyxia being an indication in 1.7%, compared with 2.5% for the total group. The frequency of operations was inversely proportional to the cervical index. Perinatal mortality was 0.53 per thousand (one case) after elective induction, 10.15 per thousand in the total group, 5.9 per thousand in those with indication for early induction. Perinatal mortality decreased from 23.0 per thousand to 7.2 per thousand from 1967 to 1974.
1875年，10537例分娩（占17.8%）采用了择期引产。与自然分娩相比，择期引产后的分娩时间即便有差异也是缩短了。择期引产后没有软组织难产的证据。择期引产后出生的儿童中，95.7%的阿氏评分在8 - 10分。择期引产后95.7%的儿童脐动脉血pH值大于或等于7.2。择期引产后枕后位的发生率显著增加（占病例的2.7%）。择期引产后手术助产分娩的发生率与所有其他分娩方式后的发生率一样频繁。择期引产后剖宫产率为4.7%，在整个系列中为11.5%，其中因宫内窒息而行剖宫产的占1.7%，而整个组的这一比例为2.5%。手术频率与宫颈指数成反比。择期引产后围产期死亡率为千分之0.53（1例），整个组为千分之10.15，有早期引产指征的为千分之5.9。1967年至1974年，围产期死亡率从千分之23.0降至千分之7.2。
