摘要
目的探讨胎心监护联合胎儿脐动脉、大脑中动脉及静脉导管分流率预测胎儿宫内窘迫的价值。方法选取105例临床怀疑胎儿宫内窘迫孕妇，所有胎儿行胎心监护（NST）；彩色多普勒超声检测各胎儿脐动脉（uA）和大脑中动脉（MCA）的阻力指数、搏动指数、S／D值；测量胎儿脐静脉、静脉导管（DV）血流量，计算静脉导管分流率，结果进行对比分析。结果NST、MCA、UA及DV分流率单独预测宫内窘迫敏感性分别为65．32％、68．23％、67．26％、61．20％；NST-4-MCA＋UA＋DV分流率联合预测的敏感性明显高于其他方法（P〈0．01）。结论NST＋MCA＋UA＋DV分流率联合应用预测胎儿宫内窘迫具有较高的敏感性和特异性。
Objective To investigate the value of the fetal heart monitoring, umbilical artery （UA）, middle cerebral artery （MCA） and ductus venosus shunting ratio as well as combing the four markers on predicting fetal distress in pregnancy. Methods One hundred and five cases of late pregnant women who were suspected with fetal distress were selected. Fetal monitoring was examined in 105 preg- nant women. Resistance index（ RI）, pulsatility index（PI） and the peak systolic velocity（S） and end di- astolic velocity（D） ratio（S/D） of fetal middle cerebral artery and umbilical artery were detected. The blood flow volume of fetal ductus venosus and umbilical vein were measured, the blood flow volume ratio of ductus venosus was calculated. The results were analyzed. Results The sensitivity of NST, MCA, UA and ductus venosus shunting ratio in predicting fetal hypoxia alone was 65.32% , 68.23% , 67.26% , 61.20%. The sensitivity of combing NST ＋ MCA ＋ UA ＋ Ductus venosus shunting ratio was higer（P 〈 0. O1 ）. Conclusions The method of combining NST ＋ MCA ＋ UA ＋ Ductus Venosus Shunting Ratio has higher sensitivity and specificity in predicting fetal distress.
