The World Health Organization considers Cesarean section rates of 5-15% to be the optimal range for targeted provision of this life saving intervention. However, access to safe Cesarean section in resource-limited settings is much lower, estimated at 1-2% reported in sub-Saharan Africa. This study reports Cesarean sections rates and indications in Democratic Republic of Congo, Burundi, and Sierra Leone, and describe the main parameters associated with maternal and early neonatal mortality.
Women undergoing Cesarean section from August 1 2010 to January 31 2011 were included in this prospective study. Logistic regression was used to model determinants of maternal and early neonatal mortality.
1276 women underwent a Cesarean section, giving a frequency of 6.2% (range 4.1-16.8%). The most common indications were obstructed labor (399, 31%), poor presentation (233, 18%), previous Cesarean section (184, 14%), and fetal distress (128, 10%), uterine rupture (117, 9%) and antepartum hemorrhage (101, 8%). Parity >6 (adjusted odds ratio [aOR] = 8.6, P = 0.015), uterine rupture (aOR = 20.5; P = .010), antepartum hemorrhage (aOR = 13.1; P = .045), and pre-eclampsia/eclampsia (aOR = 42.9; P = .017) were associated with maternal death. Uterine rupture (aOR = 6.6, P<0.001), anterpartum hemorrhage (aOR = 3.6, P<0.001), and cord prolapse (aOR = 2.7, P = 0.017) were associated with early neonatal death.
This study demonstrates that target Cesarean section rates can be achieved in sub-Saharan Africa. Identifying the common indications for Cesarean section and associations with mortality can target improvements in antenatal services and emergency obstetric care.
世界卫生组织认为,5-15%的剖宫产率是提供这种救命干预的最佳范围。然而,在资源有限的环境中,获得安全的剖宫产机会要低得多,据估计,撒哈拉以南非洲地区的报告比例为 1-2%。本研究报告了刚果民主共和国、布隆迪和塞拉利昂的剖宫产率和指征,并描述了与产妇和新生儿早期死亡相关的主要参数。
本前瞻性研究纳入了 2010 年 8 月 1 日至 2011 年 1 月 31 日期间行剖宫产术的妇女。使用逻辑回归模型分析产妇和新生儿早期死亡的决定因素。
共有 1276 名妇女接受了剖宫产术,剖宫产率为 6.2%(范围为 4.1-16.8%)。最常见的指征是梗阻性分娩(399 例,31%)、胎位不正(233 例,18%)、既往剖宫产(184 例,14%)和胎儿窘迫(128 例,10%)、子宫破裂(117 例,9%)和产前出血(101 例,8%)。产次>6(调整优势比[aOR] = 8.6,P = 0.015)、子宫破裂(aOR = 20.5;P =.010)、产前出血(aOR = 13.1;P =.045)和子痫前期/子痫(aOR = 42.9;P =.017)与产妇死亡相关。子宫破裂(aOR = 6.6,P<0.001)、产前出血(aOR = 3.6,P<0.001)和脐带脱垂(aOR = 2.7,P = 0.017)与新生儿早期死亡相关。
本研究表明,在撒哈拉以南非洲地区可以实现目标剖宫产率。确定剖宫产的常见指征及其与死亡率的关系,可以针对产前服务和紧急产科护理的改善进行有针对性的努力。
