Evaluate the incidence of births before 33 weeks of amenorrhea over a 12-year period and the place of prematurity induced among them. Determine the evolution of various causes of birth prior to that and draw up a detailed inventory.
This is a retrospective study from 1994 to 2006, concerning mothers who gave birth in the Network Users Association of computerized records in Pediatrics, Obstetrics and Gynecology (AUDIPOG) between 22 and 32+6 days of maternity. A total of 3781 deliveries were included. The statistical significance of links between the degree of prematurity (high prematurity/extreme prematurity) and the type of prematurity (induced/spontaneous) or mode of early work in the event of induced prematurity (trigger/prior cesarean work) was determined. The evolution of different etiologies was also studied with a complete inventory in 2006.
We observed a significant increase in the rate of births before 33 SA: it was multiplied by 3 in 12 years and stood at 1.7% of births in 2006. No increase in prematurity induced was observed, but in case of preterm labor induced the number of births by caesarean section increased significantly. Concerning the evolution of etiologies, vaginal and urinary infections decreased the most, followed by fetal malformations. Only multiple pregnancies increased significantly. The principle cause of preterm birth was hypertension. Prior to 28 SA, premature births were caused by metrorrhagia and infections at greater levels than 28-32 SA.
The growing number of births before 33 SA is a serious phenomenon that must be monitored as they are increasingly common in France.
评估闭经33周前分娩的发生率以及其中早产的发生情况。确定在此之前各种分娩原因的变化并编制详细清单。
这是一项1994年至2006年的回顾性研究，涉及在儿科、妇产科计算机化记录网络用户协会（AUDIPOG）于孕22至32 + 6天分娩的母亲。共纳入3781例分娩。确定早产程度（高度早产/极度早产）与早产类型（诱发/自发）或诱发早产情况下早期工作模式（触发/先前剖宫产工作）之间关联的统计学意义。还通过2006年的完整清单研究了不同病因的变化。
我们观察到妊娠33周前分娩率显著增加：12年内增加了两倍，2006年占分娩总数的1.7%。未观察到诱发早产增加，但在诱发早产的情况下，剖宫产分娩数量显著增加。关于病因变化，阴道和泌尿系统感染下降最多，其次是胎儿畸形。只有多胎妊娠显著增加。早产的主要原因是高血压。在妊娠28周前，早产由子宫出血和感染导致的比例高于28 - 32周。
妊娠33周前分娩数量增加是一个严重现象，在法国越来越普遍，必须予以监测。
