In a clinical study, 28 twin mothers were provided with epidural block during labour and delivery. This group was compared to 24 twin mothers who received conventional analgesics throughout labour. General anaesthesia was administered when operative delivery was indicated in the control group. In the epidural group, duration of labour was significantly prolonged. A delayed second stage of labour caused an increased number of operative vaginal deliveries. Intra-uterine asphyxia was not more frequent in the epidural group. Judged by the Apgar score and the neonatal course, there was no difference between the newborn in the two groups. Neither clinical evaluation, nor acid-base investigations showed any difference between the condition of Twin I and Twin II in the epidural group.
在一项临床研究中，28名双胞胎母亲在分娩过程中接受了硬膜外阻滞。该组与24名在整个分娩过程中接受传统镇痛药的双胞胎母亲进行了比较。当对照组需要进行手术分娩时，采用全身麻醉。在硬膜外组，产程明显延长。第二产程延迟导致手术助产的数量增加。硬膜外组胎儿宫内窒息的发生率并没有更高。根据阿氏评分和新生儿病程判断，两组新生儿之间没有差异。无论是临床评估还是酸碱指标检查，硬膜外组中双胞胎I和双胞胎II的状况均无差异。
