羊水过多占妊娠的1.1%~3.5%,其中胎儿和母体因素占30%~40%,60%~70%为特发性,而对后者的情况了解却贫乏。曾有人提出巨大儿和羊水过多也可发生在非糖尿病的母亲,但只限于推测。 1989年至1991年三年间,用B超连续观察99例非糖尿病孕妇伴特发性羊水过多(研究组),其胎儿无畸形,出生时也正常。与产前(n=99)、产后(n=279)对照组之间比较了预测胎儿体重(胎重)和实际出生体重。孕龄在孕早期由B超或产前检查中由末次月经确定。羊水过多以四个象限的羊水指
Excessive amniotic fluid accounts for 1.1% ~ 3.5% of pregnancy, of which 30% ~ 40% of fetuses and maternal factors, 60% ~ 70% of idiopathic, but the latter’s understanding of the situation is poor. It has been suggested that large children and polyhydramnios may also occur in non-diabetic mothers, but only speculated. Between 1989 and 1991, 99 consecutive non-diabetic pregnant women with idiopathic polyhydramnios (study group) were continuously observed with B-mode ultrasound. Their fetuses were normal and normal at birth. Predict fetal body weight (fetal weight) and actual birth weight were compared between prenatal (n = 99) and postnatal (n = 279) controls. Gestational age in the early pregnancy by the B-or prenatal examination by the last menstrual determined. Amniotic fluid with too much ammunition in four quadrants
