目的:探讨胎儿脐动脉血流S/D异常与围产儿预后的关系。方法:应用多普勒超声血流分析仪检测胎儿脐动脉血流速度,S/D值≥3且≥90th%(同孕周正常值第九十百分位)者112例为异常组,并按S/D值异常程度分为3组。随机选择同期S/D<3的158例为正常对照组,比较各组围产儿预后。结果:S/D值异常组妊娠合并症和并发症发生率为46.4%显著高于正常对照组,位于并发症首位的是重度妊娠期高血压疾病。S/D>3组围产儿不良预后与S/D<3组比较有统计学差异(P<0.01),S/D>3的3组组间比较有统计学差异(P<0.01),表明随着S/D值增高,围产儿不良预后递增。新生儿体重与S/D值呈显著负相关。结论:脐血流S/D值增高提示胎儿宫内处于不良状态,指导临床积极处理,有利于改善不良围产儿预后。
Objective: To investigate the relationship between fetal umbilical arterial blood flow S / D abnormality and perinatal outcome. Methods: Doppler ultrasound flow analyzer was used to detect the umbilical artery blood flow velocity in the fetus, with S / D ≥3 and ≥90th% (same as the 90th week of gestation) According to the abnormality of S / D value is divided into 3 groups. 158 cases of S / D <3 were randomly selected as the normal control group, and the prognosis of each group was compared. Results: The incidence of complications of pregnancy and complication in the abnormal S / D group was 46.4%, which was significantly higher than that of the normal control group. The first complication was severe hypertensive disorder. The poor prognosis of S / D> 3 groups was statistically different from that of S / D <3 groups (P <0.01), and there was a significant difference between S / D> 3 groups (P <0.01) With the S / D value increased, poor prognosis of perinatal children increased. Neonatal weight and S / D values were significantly negatively correlated. Conclusion: The increased S / D value of umbilical cord blood flow indicates that the fetus is in a bad state, guiding the clinical active treatment and improving the prognosis of poor perinatal.
