The labour records of 1000 consecutive deliveries were studied to compare the incidence of postpartum haemorrhage after induced labour with that after spontaneous labour. The discovery of an increased incidence of postpartum haemorrhage in the induced group prompted further analysis of the incidence of haemorrhage among 3674 normal deliveries. This analysis confirmed that the incidence of postpartum haemorrhage was increased after induction of labour; among primiparous patients the increased incidence after induced labours was nearly twice that after spontaneous labours, even when only normal deliveries were considered. These findings indicate that postpartum haemorrhage is another complication of induction that needs to be taken into account when induction is being considered.
研究了1000例连续分娩的产程记录，以比较引产产后出血的发生率与自然分娩产后出血的发生率。引产组产后出血发生率增加这一发现促使对3674例正常分娩中的出血发生率进行进一步分析。该分析证实引产产后出血发生率增加；在初产妇中，即使仅考虑正常分娩，引产产后出血增加的发生率也几乎是自然分娩的两倍。这些发现表明，产后出血是引产的另一种并发症，在考虑引产时需要加以考虑。
