Vaginal birth after caesarean section is the delivery of a baby through the vagina after a previous cesarean delivery. For this to be conducted safely and responsibly emergency obstetric care must be available. To study the different modes of delivery in Dhulikhel Hospital (DH), evaluate the frequency of attempted and successful vaginal birth after caesarean section and, in the VBAC group, to identify those factors that may influence outcome and safety. The study was a retrospective study of all women who were delivered via different routes and the subgroup who underwent attempted vaginal birth after caesarean section in DH from January 2007 to December 2009. In this study factors associated with the successful VBAC were also analyzed. During the study period a total of 4215 deliveries conducted in DH and a total of 890 lower segment caesarean sections (21.1% of all deliveries) were performed. Of the 890 caesareans performed, 743 were primary and 147 were repeat (69 were repeat elective and 78 were repeat emergency). In this period an additional 33 women with previous lower segment caesarean sections had a successful vaginal delivery. Hence 18.3% (33/180) vaginal birth after caesarean sections was conducted successfully among women with previous caesarean). The results of this study indicate that vaginal birth after caesarean section is a clear feature of obstetric practice in DH. This is possible because of the vigilance in managing these women and the availability in this hospital setting of resources for immediate cesarean section.
剖宫产术后经阴道分娩是指在先前剖宫产术后通过阴道分娩婴儿。要安全、负责地进行这种分娩,必须具备紧急产科护理。为了研究杜利凯尔医院(DH)的不同分娩方式,评估剖宫产术后试产和成功经阴道分娩的频率,并在剖宫产术后经阴道分娩组中确定可能影响结局和安全性的因素。该研究是一项对2007年1月至2009年12月在DH通过不同途径分娩的所有女性以及剖宫产术后试产亚组进行的回顾性研究。在这项研究中,还分析了与剖宫产术后经阴道分娩成功相关的因素。研究期间,DH共进行了4215例分娩,共进行了890例下段剖宫产(占所有分娩的21.1%)。在890例剖宫产中,743例为初次剖宫产,147例为再次剖宫产(69例为再次选择性剖宫产,78例为再次急诊剖宫产)。在此期间,另外33例有下段剖宫产史的女性成功经阴道分娩。因此,有剖宫产史的女性中,18.3%(33/180)的剖宫产术后经阴道分娩成功。本研究结果表明,剖宫产术后经阴道分娩是DH产科实践的一个明显特征。这之所以成为可能,是因为对这些女性的管理保持警惕,以及该医院具备立即进行剖宫产的资源。
