Abstract
An analysis of 18,940 deliveries between 1981 and 1984 in a large British obstetric unit showed marked changes in the management of the second stage of labour. These changes included an increase in the length of the second stage (especially among primiparous women), a rise in the rate of spontaneous delivery and a large decline in the rate of episiotomy. There was no change in neonatal outcome or in the rate of maternal postpartum complications. These findings may have resulted from a more conservative approach to the management of the second stage. They may also reflect a better understanding among obstetric professionals of what constitutes a normal second stage and therefore better decisions about when to act and when to wait.
摘要
对英国一家大型产科单位1981年至1984年间的18940例分娩进行的分析显示，分娩第二产程的管理发生了显著变化。这些变化包括第二产程时长增加（尤其是初产妇）、自然分娩率上升以及会阴切开率大幅下降。新生儿结局和产妇产后并发症发生率没有变化。这些发现可能源于对第二产程管理采取了更保守的方法。它们也可能反映出产科专业人员对正常第二产程的构成有了更好的理解，从而在何时采取行动和何时等待方面做出了更好的决策。
