A prospective randomized study was performed to determine the usefulness of x-ray pelvimetry before oxytocin induction or augmentation. Two hundred primiparous women were entered into this study. Agreement on pelvic size by the clinical and radiologic assessment occurred in 76.5% of the cases. When the total groups were compared, there were no differences in pregnancy outcome. In the induction of labor subgroups there were less forcep deliveries and lower five-minute Apgar scores in the pelvimetry group. In the augmentation subgroups there were no differences. The subgroup of patients diagnosed clinically to have a borderline pelvis, had a higher incidence of cesarean section (P less than .05) if they had x-ray pelvimetry. These results suggest that the elimination of x-ray pelvimetry in primigravida women does not lead to a compromise in infant outcome when electronic fetal monitoring is used.
进行了一项前瞻性随机研究，以确定在催产素引产或加强宫缩前进行X线骨盆测量的实用性。200名初产妇参与了这项研究。临床评估和放射学评估对骨盆大小的判断在76.5%的病例中一致。当对整个组进行比较时，妊娠结局没有差异。在引产亚组中，骨盆测量组的产钳分娩较少，5分钟阿氏评分较低。在加强宫缩亚组中没有差异。临床诊断为临界骨盆的患者亚组，如果进行了X线骨盆测量，剖宫产发生率较高（P小于0.05）。这些结果表明，在使用电子胎儿监护时，初产妇不进行X线骨盆测量不会导致婴儿结局受损。
