产程中活跃期停滞原因的分析

Causes of Active Phase Arrest

目的：探讨引起活跃期停滞的因素。方法：对１９９２～１９９４年在我院分娩的１６６例产妇（正常组８３例，停滞组８３例）的分娩记录资料进行回顾性分析。结果：（１）停滞组的新生儿平均出生体重和异常胎位发生率与正常组比较，差异有显著性；（２）停滞组的平均潜伏期与正常组比较，差异有显著性。结论：在骨盆正常的情况下，与活跃期停滞有关的主要因素是较高的新生儿出生体重和胎位异常，潜伏期的长短亦起到重要作用。

Objective: To evaluate factors affecting active phase arrest. Method: Retrospective study from 1992 to 1994 was performed. A total of 166 pregnant women were included, 83 in to the active phase arrest group and 83 in normal group. Results: There were significant differences in the average birth weight and the prevalence of abnormal fetal presentation between the 2 groups. The time length of the latent phase was another factor influencing active phase arrest. Conclusion: With normal pelvis, the high birth weight, abnormal presentation and prolonged latent phase were factors affecting active phase arrest.
