胎儿脐动脉血流测定与脐血血气分析预测新生儿预后120例

Forecasting the Prognosis of 120 Newborns by Determination of the Blood Flow of Umbilical Artery and Blood Gas Analysis

应用超声多普勒，对１２０例孕妇妊娠２６～２８周及妊娠３６～３８周各进行脐动脉血流测定１次，观察胎儿静脉血气分析，新生儿出生１ｍｉｎＡｐｇａｒ评分及羊水性状。结果：正常妊娠时，脐动脉血流速度比值（Ｓ／Ｄ）随孕周增加而减少。Ｓ／Ｄ≥３组的新生儿窒息、羊水混浊及酸中毒发生率明显率高于Ｓ／Ｄ＜３组。提示当脐动脉Ｓ／Ｄ≥３。

A draught of determination for blood flow of umbilical artery of 120 pregnant women with pregnancy of 26～28 weeks and 36～38 weeks to observe blood gas analysis of fetal veins,postnatal lminute Apgar grading marks and the condition of amniotic fluid.Results:The ratio of velocity of blood flow of umbilical artery(S/D)in normal pregnancy was decreased along with the increase of pregnancyweeks.The incidence rate of neonatal asphyxia,cloudiness of amniotic fluid and acidosis in S/D≥3 group was markedly higher than that in S/D<3 group,suggesting that the outcome of pregnancy would alter.
