目的：对妊娠晚期胎静脉导管(DV)进行血流动力学变化分析,寻找诊断胎儿窘迫并判断预后的方法。方法回顾性分析产后Apgar评分1 min<7分的146例胎儿(胎儿窘迫组)产前0~3 d内超声检查情况,分析其脐静脉导管血流动力学变化,与Apgar评分正常胎儿(正常组,150例)进行比较。结果胎儿窘迫组静脉导管心室收缩期峰值(S)、心室舒张期峰值(D)、心房收缩期峰值(A)流速均减低,阻力指数(S/A)比值增高；胎儿窘迫A组S/A比值高于胎儿窘迫B组, S、D、A流速均低于胎儿窘迫B组；差异均具有统计学意义(P<0.01)。结论进行静脉导管血流频谱检测对诊断胎儿窘迫判断预后情况有重要意义。

Objective To analyze the hemodynamic change of ductus venosus (DV) in late pregnancy, and to find method for diagnosis and prognosis judgment of fetal distress. Methods A retrospective analysis was carried out on the ultrasound examinations in prenatal 0-3 d of 146 patients with Apgar scores<7 points at postpartum 1 min (fetal distress group). The hemodynamic changes of DV were analyzed and compared to those fetuses with normal Apgar scores (normal group, n=150). Results The fetal distress group had decreased flow rates of ductus venosus ventricular systole pick (S), ventricular diastole pick (D), and atrial systole pick (A), and increased resistance index (S/A). The fetal distress group A had higher S/A value than the fetal distress group B, while its flow rates of S, D, and A were all lower than the fetal distress group B. The difference had statistical significance (P<0.01). Conclusion Application of ductus venosus blood flow spectrum detection has important significance for prognosis judgment of fetal distress.
