目的探讨无应激试验(NST)联合脐动脉血流S/D监测高危妊娠的临床应用价值。方法对112例妊娠晚期高危妊娠孕妇采用胎心监护无应激试验(NST)及脐动脉血流S/D联合监测对胎儿宫内状况作出评价并对新生儿羊水情况、阿氏评分、出生体重进行比较。结果 112例高危妊娠中S/D<3者89例(79.46%),其中反应型54例(60.67%),可疑型17例(19.10%),无反应型18例(20.23%);S/D≥3者23例(20.54%),其中反应型4例(17.39%),可疑型6例(26.09%),无反应型13例(56.52%),两组差异有统计学意义(P<0.05)。NST并S/D正常者82例,其中羊水污染3例(3.66%),阿氏评分≤7分2例(2.44%),低体重儿3例(3.66%);NST并S/D异常者5例,其中羊水污染2例(40%),阿氏评分≤7分者2例(40%),低体重儿1例(20%),两组比较差异有统计学意义(P<0.05)。结论 NST联合S/D监测高危妊娠可预测胎儿宫内安危状况,正确诊断胎儿窘迫,适时终止妊娠,在提高围产医学质量和优生起着重要的意义。
Objective To investigate the clinical value of non-stress test (NST) combined with umbilical arterial blood flow S / D in monitoring high-risk pregnancy. Methods One hundred and twelve pregnant women with high risk of third trimester of pregnancy were evaluated with fetal heart rate monitoring (NST) and umbilical arterial blood flow S / D, and the neonatal status of amniotic fluid, Asperger’s score, birth weight Compare. Results There were 89 cases (79.46%) with S / D <3 in 112 high risk pregnancies, of which 54 cases were reactive type (60.67%), 17 cases were suspicious (19.10%) and 18 cases (20.23% There were 23 cases (20.54%) with D≥3, of which 4 cases were reactive type (17.39%), 6 cases (26.09%) were suspicious and 13 cases (56.52%) were nonresponsive, with significant difference between the two groups (P < 0.05). NST and S / D were normal in 82 cases, of which amniotic fluid contamination in 3 cases (3.66%), Ashleigh score ≤ 7 points in 2 cases (2.44%), low birth weight children in 3 cases (3.66%); NST and S / D abnormalities Among them, 2 cases (40%) were amniotic fluid contamination, 2 cases (40%) with Ah score≤7 points and 1 case (20%) with low birth weight. There was significant difference between the two groups (P <0.05) . Conclusion NST combined with S / D monitoring of high-risk pregnancies can predict the status of fetal endometriosis, correct diagnosis of fetal distress, timely termination of pregnancy, in improving the quality of perinatal medicine and eugenics plays an important role.
