彩色多谱勒在不同程度妊高征胎儿脐血流检测中的应用

Application of color doppler to detect fetus' umbilical flow in women with pregnancy-induced hypertension syndrome

目的:探讨彩色多谱勒在不同程度妊高征胎儿脐血流检测中的应用价值。方法:对71例不同程度妊高征患者胎儿脐动脉血流进行测定分析。结果:随着妊高征的程度不同,胎儿脐动脉的各项血流参数具有明显的统计学差异。其收缩期峰值流速(Vs)、弹性指数(PI)与妊高征的程度成负相关;阻力指数(R I)、收缩期峰值流速(Vs)与舒张期流速(Vd)的比值(S/D)与妊高征的程度成正相关。结论:彩色多谱勒超声对于胎儿脐血流的测定可辅助于不同程度妊高征的分型,对于预测胎儿宫内缺氧情况、提示预后、帮助产科医生制定治疗方案、决定分娩的时机和方式,从而提高人口素质具有一定的实用价值。

Objective： To evaluate the value of color doppler in detecting fetus＇umbilical flow in pregnant women with different degree pregnancy-induced hypertension syndrome. Methods： The fetus＇umbilical artery flow in 71 cases with different degree pregnancy -induced hypertension syndrome were detected by color doppler. The result showed that in different degree cases there were significant differences in their artery flow indexes. Results： The Vs and PI of the fetus＇ umbilical artery flow were negatively correlated with the degree of pregnancy - induced hypertension syndrome, while the RI and S/D （ the ratio of Vs and Vd） were positively correlated with the degree of pregnancy - induced hypertension syndrome. Conclusion： The detection of color doppler in fetus＇umbilical artery flow can avail of the classification of different degree pregnancy- induced hypertension syndrome, and was valuable in predicting fetus＇anoxia, foretelling the prognosis, providing information for obstetrician to formulate treatment plan and choose puerperal time and quomodo, thereby can enhance population＇s quality.
