The purpose of this review is to examine the evidence that defines normal and abnormal amniotic fluid volumes (AFVs) and current recommendations on the management of abnormalities of AFV. The studies establishing normal actual AFVs and the ultrasound estimates used to identify normal and abnormal AFVs were evaluated. Recommendations from national and international organizations were reviewed for guidance on the definitions and management of abnormal AFVs. A timeline of the development of the thresholds that define abnormal AFVs was created. Recommendations from 13 national and international guidelines were identified, but the definitions and management recommendations for abnormal AFVs varied considerably between groups. An algorithm for the management of oligohydramnios and polyhydramnios was developed. Knowledge gaps and the structure of future studies were examined. Assessment of AFV is performed multiple times per day in antenatal clinics and hospitals. Current recommendations on defining and managing abnormal AFVs differ between national and international organizations. We have proposed algorithms to assist in the management of abnormal AFVs until further studies can be undertaken.
本综述的目的是审视界定羊水体积（AFV）正常与异常的证据，以及当前关于羊水体积异常管理的建议。对确定实际羊水体积正常的研究以及用于识别羊水体积正常与异常的超声估计方法进行了评估。审查了国家和国际组织的建议，以获取关于羊水体积异常定义和管理的指导。创建了界定羊水体积异常阈值的发展时间表。确定了13项国家和国际指南的建议，但不同组之间羊水体积异常的定义和管理建议差异很大。制定了羊水过少和羊水过多的管理算法。研究了知识空白和未来研究的架构。在产前诊所和医院中，每天会多次对羊水体积进行评估。国家和国际组织之间关于羊水体积异常定义和管理的当前建议存在差异。我们已提出算法，以协助羊水体积异常的管理，直至能够开展进一步研究。
