脐动脉舒张期血流消失时胎儿生长发育及出生情况分析

目的：分析晚孕期脐动脉舒张期血流信号消失时胎儿生长发育和出生时情况。方法采用彩色超声诊断仪检测脐动脉血流信号，对比分析脐动脉血流正常与脐动脉舒张期血流消失时胎儿的生长发育指标和出生时Apgar评分。结果脐动脉舒张期血流消失的胎儿生长发育小于孕龄的发生率明显高于正常组，出生时宫内窘迫的发生率也明显高于正常组。结论晚孕期脐动脉舒张期血流消失提示胎儿宫内缺氧，胎儿生长发育相对缓慢。

Analysis of fetus growth and development in absent end-diastolic flow

Objective To analyze the fetal growth ,development and birth situation in umbilical artery absent end‐diastolic flow(AEDF) in late pregnancy .Methods The umbilical artery blood flow signals were detected by color ultrasonic diagnostic in‐strument .The fetal growth indexes and Apgar score at birth were compared between the normal umbilical artery group and the AEDF group .Results The occurrence rate of fetal growth and development less than the gestational age was significantly higher than that in the normal group ,moreover the occurrence rate of intrauterine stress was also obviously higher than that of the normal group .Conclusion Umbilical arterial AEDF in late pregnancy prompts the fetal intrauterine hypoxia and relatively slowly fetal grow th .
