In this study of 2437 deliveries, 119 (4.9%) took place in the occiput posterior position (OP). Only 33.9% of these did not require any operative intervention, versus 82% in the occiput anterior group (OA). The total duration of labor and the duration of the second stage were significantly longer in the OP group. The Apgar scores of the newborns at 1 minute and 5 minutes were significantly lower in the OP group. Episiotomies and perineal tears were more frequent in the OP group, but the difference was not significant.
在这项针对2437例分娩的研究中，119例（4.9%）为枕后位（OP）分娩。其中只有33.9%的分娩无需任何手术干预，而枕前位组（OA）这一比例为82%。OP组的总产程和第二产程明显更长。OP组新生儿1分钟和5分钟时的阿氏评分明显更低。OP组的会阴切开术和会阴撕裂更为常见，但差异不显著。
