摘要: 本文探讨母胎动态心电图心电监测(Holter)辅助彩色多普勒超声(CDFI)、Tei指数预测胎儿宫内窘迫的价值。选取进行产前登记、分娩的孕妇作为研究对象,其中53例出现胎儿窘迫症状的孕妇作为窘迫组,同期未出现胎儿窘迫症状的100例孕妇作为对照组。两组均进行动态心电图监测,采用CDFI检测胎儿脐动脉、大脑中动脉的阻力指数(RI)、搏动指数(PI)、收缩期与舒张期峰值血流比值(S/D)、Tei指数。结果显示,窘迫组的PELV测定值高于对照组(P<0.05);窘迫组的脐动脉、大脑中动脉的PI、RI、S/D测定值均高于对照组孕妇(P<0.05);窘迫组的Tei指数测定值高于对照组(P<0.05);PELV测定值预测胎儿窘迫的最佳临界值为18.68%,曲线下面积为0.655;PELV+脐动脉S/D值+大脑中动脉S/D值+Tei指数联合预测胎儿窘迫的灵敏度为90.57%、特异度为87.00%。临床上,单独用Holter预测胎儿宫内窘迫敏感性较差,作为辅助手段联合CDFI、Tei指数预测胎儿宫内窘迫具有更好的效果。

Abstract: This paper discussed the value of the maternal dynamic ECG monitoring (Holter) assisted color Doppler ultrasound (CDFI) and Tei index in predicting fetal intrauterine distress. The pregnant women who registered and gave birth were selected as the research object. Among them, 53 pregnant women with fetal distress symptoms were selected as the distress group, and 100 pregnant women without fetal distress symptoms during the same period were selected as the control group. The two groups were monitored by Holter, and CDFI was used to detect fetal umbilical artery and middle cerebral artery resistance index (RI), pulsatility index (PI), systolic to diastolic peak blood flow ratio (S/D), and Tei index. The PELV values in the distress group were higher than those in the control group (P<0.05). The measured values of PI, RI, and S/D of the umbilical artery and middle 367 cerebral artery in the distress group were higher than those in the control group (P<0.05). The Tei index value of the distress group was higher than that of the control group (P<0.05). The best cut-off value of PELV value for predicting fetal distress was 18.68%, and the area under the curve was 0.655. The sensitivity of PELV + umbilical artery S/D value + brain arterial S/D value + Tei index to predict fetal distress was 90.57%, and specificity was 87.00%. Clinically, the sensitivity of Holter alone to predict fetal distress is poor. As an auxiliary method, combined with CDFI and Tei index to predict fetal distress has a better effect.
