Abstract

OBJECTIVE

This study was undertaken to determine whether there is a correlation between neonatal birth weight and an estimated or dye-determined amniotic fluid volume.

STUDY DESIGN

A prospective observational study of women undergoing an amniocentesis and subsequent delivery within 72 hours. Amniotic fluid volume was estimated using the amniotic fluid index (AFI) and single deepest pocket technique and calculated by the dye-dilution technique.

RESULTS

One hundred seventy-five women participated in the study. Linear regression modelling showed no significant relationship between birth weight and amniotic fluid volume adjusted for gestational age (P=.062). Similarly, there was no evidence of an association between birth weight and a dye determined amniotic fluid volume (P=.180), fixed cutoffs for the AFI (P=.224), percentiles for the AFI (P=.112), or fixed cutoffs for the single deepest pockets (P=.867).

CONCLUSION

Neonatal birth weight is not correlated with a dye-determined or ultrasound estimated amniotic fluid volume.

摘要

目的

本研究旨在确定新生儿出生体重与估计或染料测定的羊水量之间是否存在相关性。

研究设计

一项对在72小时内接受羊膜穿刺术及随后分娩的女性进行的前瞻性观察性研究。使用羊水指数（AFI）和单一最深羊水池技术估计羊水量，并通过染料稀释技术计算羊水量。

结果

175名女性参与了该研究。线性回归模型显示，经孕周调整后，出生体重与羊水量之间无显著关系（P = 0.062）。同样，也没有证据表明出生体重与染料测定的羊水量（P = 0.180）、AFI的固定临界值（P = 0.224）、AFI的百分位数（P = 0.112）或单一最深羊水池的固定临界值（P = 0.867）之间存在关联。
