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 study the correlation between S / D value of pregnant umbilical artery in late pregnant women and pregnancy complications, complications, fetal prognosis and cesarean section rate, and to apply it in clinical diagnosis and treatment. Methods From January to December in 2013, 3 610 cases delivered from Xiamen Hospital of Traditional Chinese Medicine Affiliated to Fujian University of Traditional Chinese Medicine were measured color Doppler flow imaging (CDFI) from the third trimester to the first trimester of pregnancy. (S / D value). According to the data of S / D <2.5, 2.5≤S / D <3.0 and S / D≥3.0, the differences of S / D and late pregnancy complications, complications, Fetal prognosis, the relationship between cesarean section, the application of χ2 test. Results A total of 841 cases (24.37%) of pregnancy complications and complications, 465 cases (13.47%) of fetal distress, 86 cases (2.49%) of neonatal asphyxia, severe asphyxia 19 (0.55%), 10 cases of perinatal death (0.29%) and 1 073 cases of cesarean section (31.09%). In the group of 2.5≤S / D <3.0, there were 68 cases of pregnancy complications and complications (55.28% ), 32 cases of fetal distress (26.02%), mild neonatal asphyxia in 11 cases (8.94%), severe asphyxia in 3 cases (2.44%), perinatal death in 3 cases (2.44%) and cesarean section in 57 cases 46.34%). In S / D≥3.0 group, 34 cases (94.44%) had complications and complications of pregnancy, 15 cases (41.67%) had fetal distress, 7 cases (19.44%) had neonatal asphyxia, Severe asphyxia in 3 cases (8.33%), perinatal death in 2 cases (5.56%), cesarean section in 24 cases (66.67%). The differences among groups were statistically significant (P <0.05). Conclusion The determination of S / D of umbilical artery should be emphasized in prenatal pregnancy, especially in high-risk pregnancy. It has important clinical significance in improving fetal prognosis and reducing perinatal mortality after labor.
