In France, 75% of annual preterm births happen between 34 and 36 weeks+6 days. This study's goal is to describe the main causes and short-term consequences.
Two hundred and ninety-seven computerized files of patients who gave birth between 34 and 36 weeks+6 days at the hospital Foch's maternity were analyzed retrospectively. Descriptive statistical analysis was done with XLSTAT 2008.
Among the 6028 births, 4.9% happened between 34 and 36 weeks+6 days and 43.1% of these births were medically induced. The two main causes of induced late preterm birth were: pre-eclampsia (28.9%) and premature rupture of membranes (25%). In spontaneous deliveries, newborns less often require respiratory support at birth (17.2% vs 31%; P=0.02) and are significantly less likely to be hospitalized in neonatology (54% vs 72.3%; P<0.01). C-section rates (71.1% vs 17.75%; P<0.01) and post-partum hemorrhages' probability (10.2% vs 3%; P<0.01) are significantly higher than for medically induced deliveries.
Better knowledge of late prematurity causes and consequences would help limit medically induced births after 34 weeks.
在法国，每年75%的早产发生在孕34至36周加6天之间。本研究的目的是描述主要原因和短期后果。
回顾性分析了福煦医院妇产科34至36周加6天分娩的297例患者的计算机化病历。使用XLSTAT 2008进行描述性统计分析。
在6028例分娩中，4.9%发生在34至36周加6天之间，其中43.1%的分娩是医源性引产。晚期早产医源性引产的两个主要原因是：子痫前期（28.9%）和胎膜早破（25%）。在自然分娩中，新生儿出生时较少需要呼吸支持（17.2%对31%；P = 0.02），入住新生儿科的可能性显著降低（54%对72.3%；P < 0.01）。剖宫产率（71.1%对17.75%；P < 0.01）和产后出血概率（10.2%对3%；P < 0.01）显著高于医源性引产分娩。
更好地了解晚期早产的原因和后果将有助于减少34周后医源性引产的发生。
