【摘要】：目的分析晚孕期臍動(dòng)脈舒張期血流信號(hào)消失時(shí)胎兒生長(zhǎng)發(fā)育和出生時(shí)情況。方法采用彩色超聲診斷儀檢測(cè)臍動(dòng)脈血流信號(hào),對(duì)比分析臍動(dòng)脈血流正常與臍動(dòng)脈舒張期血流消失時(shí)胎兒的生長(zhǎng)發(fā)育指標(biāo)和出生時(shí)Apgar評(píng)分。結(jié)果臍動(dòng)脈舒張期血流消失的胎兒生長(zhǎng)發(fā)育小于孕齡的發(fā)生率明顯高于正常組,出生時(shí)宮內(nèi)窘迫的發(fā)生率也明顯高于正常組。結(jié)論晚孕期臍動(dòng)脈舒張期血流消失提示胎兒宮內(nèi)缺氧,胎兒生長(zhǎng)發(fā)育相對(duì)緩慢。
[Abstract]:Objective to analyze the fetal growth and development in late pregnancy when the diastolic flow signal of umbilical artery disappeared. Methods the umbilical artery blood flow signal was detected by color ultrasound. The fetal growth and development indexes and the Apgar score at birth were compared between normal umbilical artery blood flow and umbilical artery diastolic blood flow disappearance. Results the fetal growth and development of umbilical artery diastolic blood flow disappeared was less than that of gestational age. The rate was significantly higher than that in the normal group. Conclusion the disappearance of umbilical artery diastolic blood flow in late pregnancy indicates that fetal intrauterine hypoxia and fetal growth and development are relatively slow.

【正文快照】： 臍動(dòng)脈是連接胎盤與胎兒的紐帶,是胎兒與母體氣體和物質(zhì)交換的通道。在某些病理情況下,臍動(dòng)脈的阻力增加,在彩色多普勒超聲中表現(xiàn)為S/D值增高,當(dāng)阻力進(jìn)一步增高時(shí),表現(xiàn)為舒張期血流信號(hào)消失(absent end-diastolic flow,AEDF)甚至反流(reversed end-diastolic flow,REDF)。有研
