摘要： 本文研究超声检测脐血流收缩期最大血流峰值/舒张期最小血流峰值(S/D)、胎儿主动脉峡部血流指数(IFI)、脑胎盘率(CPR)预测胎儿宫内生长受限(IUGR)的效能及意义。选取接受产检的498例孕妇作为研究对象,根据是否发生IUGR分为IUGR组(n=33)和无IUGR组(n=465),比较两组基线资料、S/D、IFI、CPR、胎儿体重估测(EFW),并对数据进行统计分析。结果显示,IUGR组S/D(2.90±0.52)显著高于无IUGR组(P<0.05),IFI(0.75±0.44)、CPR(1.18±0.38)、EFW[(2169.33±483.05)g]显著低于无IUGR组(P<0.05);S/D与EFW呈负相关,IFI、CPR与EFW呈正相关(P<0.05);将妊娠高血压、EFW控制后,S/D、IFI、CPR仍与IUGR发生有关(P<0.05)。故应用超声联合检测S/D、IFI、CPR、EFW可作为评估IUGR的一个有效方案,为临床诊疗提供参考依据。

Abstract: In this paper, the ultrasound detection of cord blood flow during systolic maximum blood flow peak/diastolic minimum blood flow peak (S/D), fetal aortic isthmus blood flow index (IFI), brain placental rate (CPR) to predict fetal intrauterine growth restriction (IUGR) efficacy and significance were studied. A total of 498 pregnant women who underwent prenatal check-ups were selected as the research objects. According to whether IUGR occurred, they were divided into IUGR group (n=33) and no IUGR group (n=465). The baseline data of the two groups were compared. S/D, IFI, CPR, estimation fetal weight (EFW), and statistical analysis of the data. The results showed that the S/D (2.90±0.52) of the IUGR group was higher than that of the no IUGR group (P<0.05), and the IFI (0.75±0.44), CPR (1.18±0.38), and EFW [(2169.33±483.05)g] were lower than those without IUGR (P<0.05) in the IUGR group; S/D was negatively correlated with EFW, and IFI, CPR and EFW were positively correlated (P<0.05). After the control of hypertension and EFW during pregnancy, S/D, IFI and CPR were still related to the occurrence of IUGR (P<0.05). Therefore, the combined detection of S/D, IFI, CPR, and EFW by ultrasound can be used as an effective program to evaluate IUGR, and provide a reference for clinical diagnosis and treatment.
