彩色多普勒及无应激试验联合应用测定围生儿预后

Colour Dopplor Ultrasonography and NST in Estimating Perinatal Fetal Status

目的：探讨彩色多普勒、无应激试验（NST）联合应用预测围生儿结局的临床价值。方法：选取2011年1月-2012年12月在笔者所在医院分娩的158例无应激试验监护异常的孕妇作为研究对象，应用彩色多普勒超声诊断仪，进行UAM（胎儿脐动脉阻力指标）监测。结果：UMA异常产妇的围生儿预后不良发生率显著高于UMA正常者，比较差异有统计学意义（P〈0.05）；在末次检测距妊娠结束时间≤2 d时的围生儿预后不良发生率显著低于距分娩3~7 d时检测的围生儿预后不良发生率，比较差异有统计学意义（P〈0.05）。结论：对于UMA正常、无应激试验异常的孕妇，不需要进行早期妊娠干预，动态观察即可，NST异常且脐动脉阻力指标异常者，宜尽早终止妊娠。

Objective：To explore clinical value of color Doppler, non-stress test（NST） jointly predict the outcome of perinatal child.Method： 158 cases of pregnant women with abnormal NST detected as the research object, who were used color Doppler detection fetal UAM（umbilical artery resistance index）.Result： UMA abnormal maternal perinatal children of poor prognosis were significantly higher than UMA normal, and the difference was statistically significant（P〈0.05）. The poor incidence prognosis in perinatal at last detected at the end of pregnancy time ≤2 d were significantly lower than at birth 3-7 d detected, and the difference were statistically significant（P＆lt;0.05）.Conclusion： UAM normal and no NST mothers can without intervention early pregnancy, just dynamic observation is ok. NST abnormalities and abnormal umbilical artery resistance index should be an early termination of pregnancy.
