256例胎儿脐带缠绕脐动脉S/D值联合无应激试验与预后关系的分析

Analysis the relationship between umbilical arterial S/D value,taixin monitoring and fetal outcomes on 256 cases of umbilical cord around

目的探讨脐带缠绕时胎儿脐动脉S/D联合胎心监护无应激试验(NST)对评估胎儿预后的临床价值。方法回顾性分析256例脐带缠绕时胎儿的脐动脉S/D值及联合胎心监护,按有反应型S/D≤3.0+NST与S/D>3.0+NST进行比较;无反应型S/D≤3.0+NST与S/D>3.0+NST进行比较,观察脐动脉S/D值联合NST与胎儿预后的关系。结果当NST为无反应型时,随着脐动脉S/D值的升高羊水胎粪污染及新生儿窒息的发生率、剖宫产率也会随之上升,差异有统计学意义(P<0.05)。结论测定脐动脉S/D值联合NST,比单纯测定脐动脉S/D值或NST判断胎儿窘迫更准确,可降低围产儿病死率。

Objective To explore the clinical value of umbilical arterial S/D value and taixinmMonitoring on fetal outcome in the situation of umbilical cord around. Methods The fetus umbilical cord winding umbilical arterial S/D ratio and taixin Monitoring of 256 cases were retrospectively analyzed. Compare S/D≤3.0＋NST with S/D〉3.0＋NST if there is reaction, and compare S/D≤ 3.0 ＋ NST and S/D〉3.0＋ NST if without, and then observe the relationship between the umbilical arterial S/D value, taixin monitoring and fetal outcome. Results As S/D value rising and NST resulted non reaction type, amniotic fluid tire fouling and neonatal asphyxia incidence rise subsequently too, cesarean section rate also rises subsequently, there was a significant difference（P〈0. 05）. Conclusion Measuring the umbilical arterial S/D value and TaiXin guardianship to detect the fetal distress is more accurate than only measuring one of the two items, it can judge fetal hypoxia, improve fatal outcome and decrease the prenatal mortality rate.
