PURPOSE
This study aimed to determine the clinical significance of echogenic amniotic fluid.
METHODS
We prospectively studied 19 twin pregnancies in which the amniotic fluid in 1 sac was anechoic and that in the other sac was echogenic. Morphologic characteristics of amniotic fluid were assessed from samples taken at amniocentesis or upon delivery within 48 hours after sonographic examination.
RESULTS
In twins with echogenic amniotic fluid, assessment revealed clear fluid in 6 cases (32%), vernix caseosa in 12 (63%), and meconium in 1 (5%). In co-twins with anechoic amniotic fluid, assessment revealed clear fluid in 9 cases (47%), vernix caseosa in 6 (32%), and meconium in 4 (21%).
CONCLUSIONS
Echogenic amniotic fluid on prenatal sonography is not predictive of meconium.
目的
本研究旨在确定羊水呈强回声的临床意义。
方法
我们前瞻性地研究了19例双胎妊娠，其中一个羊膜囊内的羊水无回声，另一个羊膜囊内的羊水呈强回声。在超声检查后48小时内，通过羊膜腔穿刺取样或分娩时获取的样本评估羊水的形态学特征。
结果
在羊水呈强回声的双胎中，评估显示6例（32%）为清亮液体，12例（63%）为胎脂，1例（5%）为胎粪。在羊水无回声的双胎中，评估显示9例（47%）为清亮液体，6例（32%）为胎脂，4例（21%）为胎粪。
结论
产前超声检查时羊水呈强回声并不能预测胎粪情况。
