The caesarean delivery (CD) rate has risen in most countries over the last decades, but it remains relatively low in the Netherlands. Our objective was to analyse the trends of CD rates in various subgroups of women between 2000 and 2010, and identify the practice pattern that is attributable to the relative stability of the Dutch CD rate.
A total of 1,935,959 women from the nationwide Perinatal Registry of the Netherlands were included. Women were categorized into ten groups based on the modified CD classification scheme. Trends of CD rates in each group were described.
The overall CD rate increased slightly from 14.0% in 2000-2001 to 16.7% in 2010. Fetal, early and late neonatal mortality rates decreased by 40-50% from 0.53%, 0.21%, 0.04% in 2000-2001 to 0.29%, 0.12%, 0.02% in 2010, respectively. During this period, the prevalence of non-vertex presentation decreased from 6.7% to 5.3%, even though the CD rate in this group was high. The nulliparous women with spontaneous onset of labor at term and a singleton child in vertex presentation had a CD rate of 9.9%, and 64.7% of multiparous women with at least one previous uterine scar and a singleton child in vertex presentation had a trial of labor and the success rate of vaginal delivery was 45.9%.
The Dutch experience indicates that external cephalic version for breech presentation, keeping the CD rate low in nulliparous women and encouraging a trial of labor in multiparous women with a previous scar, could help to keep the overall CD rate steady.
在过去几十年中,大多数国家的剖宫产率都有所上升,但荷兰的剖宫产率仍然相对较低。我们的目的是分析2000年至2010年间不同亚组女性的剖宫产率趋势,并确定导致荷兰剖宫产率相对稳定的实践模式。
纳入了荷兰全国围产期登记处的1,935,959名女性。根据改良的剖宫产分类方案,将女性分为十组。描述了每组剖宫产率的趋势。
总体剖宫产率从2000 - 2001年的14.0%略有上升至2010年的16.7%。胎儿、早期和晚期新生儿死亡率分别从2000 - 2001年的0.53%、0.21%、0.04%下降了40 - 50%,至2010年分别为0.29%、0.12%、0.02%。在此期间,非头位分娩的发生率从6.7%降至5.3%,尽管该组的剖宫产率较高。足月自然发动分娩且为单胎头位的初产妇剖宫产率为9.9%,至少有一次子宫瘢痕且为单胎头位的经产妇中有64.7%尝试阴道分娩,阴道分娩成功率为45.9%。
荷兰的经验表明,臀位外倒转术、保持初产妇低剖宫产率以及鼓励有既往瘢痕的经产妇尝试阴道分娩,有助于保持总体剖宫产率稳定。
