探讨尿Ｅ／Ｃ比值与胎儿预后的关系及分娩方式对低Ｅ／Ｃ比值胎儿预后的影响，并对其临床意义进行客观评价。结果显示：在正常妊娠中有２０．３０％～２４．４３％尿Ｅ／Ｃ比值为低值，在高危妊娠中，重度妊高征和过期妊娠低Ｅ／Ｃ比值率最高，分别为４４．９５％和３２．５１％；尿Ｅ／Ｃ比值低者胎儿窘迫、低Ａｐｇａｒ评分和围产儿死亡率明显增高（Ｐ＜０．０１），连续测定表明Ｅ／Ｃ比值下降者低Ａｐｇａｒ评分和围产儿死亡率明显高于上升型和水平型（Ｐ＜０．０１），在尿Ｅ／Ｃ比值低值、羊水≤２ｃｍ和ＮＳＴ阳性的孕妇中，低Ａｐｇａｒ评分和围产儿死亡率较高，分别为６３．４２％和１４．６３％；当低Ｅ／Ｃ比值时，产程延长和急诊剖宫产者胎儿预后不良的发生率明显增高（Ｐ＜０．０１）。检测孕妇尿Ｅ／Ｃ比值对监护高危妊娠、筛选胎盘功能不全、预测胎儿预后方面具有重要的临床意义。连续测定或多指标联合测定，可提高判定胎儿预后的准确性。
To investigate the relationship between urinary E / C ratio and fetal prognosis and the effect of mode of delivery on the prognosis of fetus with low E / C ratio, and evaluate its clinical significance objectively. The results showed that in normal pregnancy, there was a low E / C ratio of 20.30% to 24.43%. In high-risk pregnancies, the low E / C ratio of severe PIH and late pregnancy was the highest (44%, respectively). 95%, and 32.51%, respectively. The low urinary E / C ratio in fetal distress, low Apgar score and perinatal mortality were significantly higher (P <0.01). The continuous determination of low Apgar score and circumference The neonatal mortality rate was significantly higher than that of the ascending and the horizontal type (P <0.01). In low urinary E / C ratio, amniotic fluid ≤2cm and NST positive pregnant women, the low Apgar score and perinatal mortality were higher Were 63.42% and 14.63%, respectively. When the ratio of E / C was low, the incidence of prolonged labor and fetal malformation in emergency cesarean section was significantly higher (P <0.01). Detection of urinary E / C ratio of pregnant women monitoring of high-risk pregnancy, screening placental insufficiency, prognosis of fetal prognosis has important clinical significance. Continuous measurement or multiple indicators combined determination can improve the accuracy of the determination of fetal prognosis.
