Amnioinfusion is commonly used for the intrapartum treatment of women with pregnancy complicated by thick meconium or oligohydramnios with deep variable fetal heart rate decelerations. Its benefit in women with previous cesarean deliveries is less known. Theoretically, rapid increases in intrauterine volume would lead to a higher risk of uterine rupture.
Searches of the Cochrane Library from inception to the third quarter of 2001 and MEDLINE, 1966 to November 2001, were performed by using keywords "cesarean" and "amnioinfusion." Search terms were expanded to maximize results. All languages were included. Review articles, editorials, and data previously published in other sites were not analyzed.
Four studies were retrieved having unduplicated data describing amnioinfusion in women who were attempting a trial of labor after previous cesarean section. As the studies were of disparate types, meta-analysis was not possible.
The use of amnioinfusion in women with previous cesarean delivery who are undergoing a trial of labor may be a safe procedure, but confirmatory large, controlled prospective studies are needed before definitive recommendations can be made.
羊膜腔灌注常用于分娩期治疗合并胎粪黏稠或羊水过少且伴有重度变异型胎儿心率减速的孕妇。其对有剖宫产史孕妇的益处尚鲜为人知。理论上，子宫内容积的快速增加会导致子宫破裂风险升高。
检索考克兰图书馆建库至2001年第三季度以及MEDLINE数据库1966年至2001年11月期间的数据，使用关键词“剖宫产”和“羊膜腔灌注”进行检索。对检索词进行扩展以最大化检索结果。纳入所有语言的文献。未分析此前在其他网站发表的综述文章、社论及数据。
检索到四项研究，其数据未重复，描述了有剖宫产史且尝试经阴试产的孕妇接受羊膜腔灌注的情况。由于这些研究类型各异，无法进行荟萃分析。
有剖宫产史且正在经阴试产的孕妇使用羊膜腔灌注可能是一种安全的操作，但在做出明确推荐之前，需要开展大规模、对照性的前瞻性研究加以证实。
