To understand the role of fetal spine position in determining a fetal head position at the time of birth and modality of delivery.
This was a multicenter prospective observational study. Fetal occiput and spine position were evaluated by intrapartum ultrasound. Eighty-six women were eligible for inclusion in the study. Occiput rotational movements and modality of delivery in relation to the fetal spine position were investigated.
At the beginning of labor, fetal occiput was in a posterior position in 52.3% of cases and, in 81.5% of cases the spine was in an anterior transverse position. At birth, occiput and spine were both in an anterior position in 90.4% of cases. The rate of cesarean sections in the SP group was significantly higher than the rate in the SAT group (50% vs. 8%, p < 0.0007). Instead, the rate of vaginal deliveries without intervention in the SP group was significantly lower than the rate in the SA group (14% vs. 71%, p < 0.0001).
Fetal spine position could have an important role in determining fetal occiput position at birth. Spine position might play a crucial role in the outcome of delivery.
了解胎儿脊柱位置在确定出生时胎儿头部位置及分娩方式中的作用。
这是一项多中心前瞻性观察研究。通过产时超声评估胎儿枕部和脊柱位置。86名女性符合纳入该研究的条件。研究了枕部旋转运动及与胎儿脊柱位置相关的分娩方式。
分娩开始时，52.3%的病例胎儿枕部处于后位，81.5%的病例脊柱处于前横位。出生时，90.4%的病例枕部和脊柱均处于前位。脊柱后位组剖宫产率显著高于脊柱前位组（50%对8%，p<0.0007）。相反，脊柱后位组无干预阴道分娩率显著低于脊柱前位组（14%对71%，p<0.0001）。
胎儿脊柱位置在确定出生时胎儿枕部位置方面可能起重要作用。脊柱位置可能在分娩结局中起关键作用。
