摘　　要：目的研究孕妇晚期妊娠脐动脉S/D测定值与妊娠并发症、合并症、胎儿预后、剖宫产诸率的关联性,并运用于临床诊疗。方法选择2013年1-12月在福建中医药大学附属厦门市中医院分娩的3 610例于妊娠晚期至临产前使用彩色多普勒血流显像(CDFI)测定脐动脉血流收缩末期峰值与舒张末期峰值(S/D值)的临床资料,按S/D<2.5、2.5≤S/D<3.0、S/D≥3.0分组,分析不同S/D值与妊娠晚期并发症、合并症、胎儿预后、剖宫产的关系,应用χ2检验。结果在S/D<2.5组中,妊娠并发症与合并症共841例(24.37%)、胎儿宫内窘迫465例(13.47%)、新生儿轻度窒息86例(2.49%)、重度窒息19例(0.55%)、围产儿死亡10例(0.29%)、剖宫产1 073例(31.09%);在2.5≤S/D<3.0组中,妊娠并发症与合并症共68例(55.28%)、胎儿宫内窘迫32例(26.02%)、新生儿轻度窒息11例(8.94%)、重度窒息3例(2.44%)、围产儿死亡3例(2.44%)、剖宫产57例(46.34%);在S/D≥3.0组中,妊娠并发症与合并症共34例(94.44%)、胎儿宫内窘迫15例(41.67%)、新生儿轻度窒息7例(19.44%)、重度窒息3例(8.33%)、围产儿死亡2例(5.56%)、剖宫产24例(66.67%)。各组间比较,差异均有统计学意义(P<0.05)。结论晚期妊娠临产前特别是高危妊娠应重视脐动脉S/D值的测定,对分娩时改善胎儿预后、降低围产儿死亡率有重要临床指导意义。[ Objective ] To analyze the relationship between umbilical artery blood flow S/D and the pregnancy complications and outcoms,including fetal prognosis, uterine-incision delivery, then to use to guide clinical practice. [ Methods ] A retrospective study design was used with 3610 cases of pregnant women who received color doppler flow imaging and umbilical blood flow in late trimester of pregnancy before abortion from January 2013 to December 2013 in our hospital.All the selected subjects were classified three groups by S/D〈2.5,2.5 ≤ S/D〈3.0,S/D ≥ 3.We analyzed the relationship between umbilical blood flow S/D and the pregnancy complications and outcoms,including fetal prognosis, uterine-incision delivery.Statistical analysis used was the chi-squared test. [ Results ] In the Group of S/D〈2.5,841 cases of pregnancy complications（24.37%）,465 cases of fetal distress（13.47%）,86 cases of neonatal mild asphyxia（2.49%）,19 cases of severe asphyxia（0.55%）,10 cases of perinatal death（0.29%）,1073 cases of esarean section（31.09%）; In the group 2.5≤S/D〈3.0,68 cases of pregnancy complications（55.28%）,32 cases of fetal distress（26.02%）,11 cases of neonatal mild asphyxia（8.94%）,3 cases of severe asphyxia（2.44%）,3 cases of perinatal death（2.44%）,57 cases of cesarean section（46.34%）;In the group of S/D ≥ 3,0,34 cases of pregnancy complications（94.44%）,15 cases of fetal distress （41.67%）,7 cases of neonatal mild asphyxia（19.44%）,3 eases of severe asphyxia （8.33%）, 2 eases of perinatal death（5.56%）,24 cases of cesarean section（66.67%）.By comparison,the differences between groups were statistically significant（P〈0.005）. [ Conclusion ] We should pay attention to measured umbilical artery S/D before labor in late pregnancy,especially for high risk pregnancy.It has important clinical significance for the fetus during labor to improve prognosis and reduce perinatal mortality.
