In Germany the rate of deliveries by cesarean section is continually increasing. Many different reasons have been put forward to explain this trend. The aim of this study was to examine how the C-section rate developed at the University Gynecology Clinic Rostock, one of the biggest maternity hospitals and level I perinatal centers in Germany, based on various maternal and neonatal parameters. The aim was also to identify potential risk factors for C-sections.
Various obstetric parameters were obtained from the birth cohort (2008 to 2014; n = 20 091) of the University Gynecology Clinic Rostock. The data was used to calculate parameter-specific C-section rates. Potential risk factors for C-section were identified by regression analysis.
The C-section rate dropped from 26.24% to 23.57%. The rate of repeat C-sections also declined. The mean age of the pregnant women increased. Nevertheless, the frequency of cesarean sections in pregnant women aged more than 35 years declined. Rates of being overweight or obese preconception increased. C-section rates increased as BMI values preconception increased. There was a perceptible trend towards attempting the vaginal delivery of children in breech presentation and of twins. The frequency of depressed neonates after vaginal delivery and after C-section decreased. Rates for mild and advanced acidosis increased after both C-sections and vaginal deliveries. Previous C-section, older maternal age, overweight and obesity prior to conception, breech presentation and multiple pregnancies all increased the risk of cesarean sections.
This study showed that reducing the rates of C-sections without a deterioration in neonatal outcomes can be achieved even in a large maternity hospital that cares for many high-risk pregnancies.
在德国,剖宫产率持续上升。人们提出了许多不同的原因来解释这一趋势。本研究的目的是基于各种母体和新生儿参数,考察德国最大的妇产医院之一、一级围产期中心罗斯托克大学妇科诊所的剖宫产率是如何变化的。研究目的还包括确定剖宫产的潜在风险因素。
从罗斯托克大学妇科诊所的出生队列(2008年至2014年;n = 20091)中获取各种产科参数。这些数据用于计算特定参数的剖宫产率。通过回归分析确定剖宫产的潜在风险因素。
剖宫产率从26.24%降至23.57%。再次剖宫产率也有所下降。孕妇的平均年龄增加。然而,35岁以上孕妇的剖宫产频率下降。孕前超重或肥胖的发生率增加。剖宫产率随着孕前BMI值的增加而上升。对于臀位胎儿和双胞胎,尝试经阴道分娩有明显的趋势。经阴道分娩和剖宫产后新生儿抑郁的发生率降低。剖宫产后和经阴道分娩后轻度和重度酸中毒的发生率均增加。既往剖宫产、产妇年龄较大、孕前超重和肥胖、臀位及多胎妊娠均增加了剖宫产的风险。
本研究表明,即使在一家照顾许多高危妊娠的大型妇产医院,也能够在不降低新生儿结局的情况下降低剖宫产率。
