胎儿脐动脉血流速度与新生儿结局的关系(附166例分析)

The relationship between fetal umbilical arterial blood flow velocity and the outcome of neonate(analysis of 166 cases)

目的 :探讨胎儿脐动脉血流速度与新生儿结局的关系。方法 :对 166名孕妇的脐动脉收缩期峰值 (S)与舒张末期峰值 (D)比值 (S/D比值 )测定结果、新生儿结局进行回顾性分析。结果 :S/D比值异常者 17例 ,其中小于胎龄儿 12例 (70 % ) ,新生儿死亡 3例 (18% ) ;正常 149名中小于胎龄儿7例 (5 % ) ,无新生儿死亡。两组比较有显著性差异。结论 :胎儿脐动脉 S/D比值可作为评估新生儿结局的一个重要指标。

Objective:To study the relationship between the fetal umbilical arterial blood flow velocity and the outcome of neonate Method:The fetal umbilical arterial systolic peak value/end-diastolic peak value(S/D) radios were determined in 166 pregnant women. A retrospective analysis was performed to analyse their relationships to the outcome of neonates Results:12 cases of 17 cases with abnormal S/D ratios came out to be small-for gestational age fetus (SGA fetus,70%)and 3 cases led to neonatal death(18%) There was significant difference compared to the group with normal S/D ratio (7/149 being SGA,5%,no neonatal death) Conclusion:The fetal arterial S/D ratio may be an important index to evaluate the outcome of neonate
