概括
剖腹产后的阴道分娩 (VBAC) 是可行的,但与正常的阴道分娩 (NVB) 相比,其子宫破裂和产后出血的风险更高. 谨慎的患者选择和监测对于安全的VBAC结果至关重要.
科学领域:
- 产科和妇科 产科和妇科
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 生殖健康 生殖健康
背景情况:
- 剖腹产后的阴道分娩 (VBAC) 是重复剖腹产的替代方案.
- 了解VBAC和正常阴道分娩 (NVB) 的比较结果对于临床决策至关重要.

- 为了评估VBAC在外周止痛下成功率.
- 为了确定与VBAC相关的风险因素.
主要方法:
- 对1024名通过阴道分娩的女性进行了回顾性队列研究 (2019年1月 - 2020年12月).
- 对VBAC (n=512) 和NVB (n=512) 组进行比较,所有这些组都接受了外周止痛.
- 统计分析包括描述性统计,奇平方测试和后勤回归 (SPSS v25.0).
主要成果:
- VBAC的成功率为87.5%,而NVB的成功率为100%.
- VBAC与子宫破裂增加 (0.8%对0%),产后出血 (6.6%对3.5%) 和需要输血 (2.7%对0.8%) 相关.
- 在VBAC组中观察到较高的低5分钟Apgar分数和NICU入院率.
结论:

01:30Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

01:28Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
