不同孕期维、汉孕妇超声监测子宫动脉差异性分析

Analysis of differences of uterine artery blood flow indexes of Uighur and Han pregnant women at different gestational weeks by ultrasound monitoring

目的:通过监测孕妇子宫动脉早、中孕期指标,研究不同孕期孕妇子宫动脉血流动力学的差异及维、汉民族间孕妇不良妊娠发生与其子宫动脉血流指标相关性的差异。方法:通过对202例维、汉两民族孕妇在早、中孕期进行超声检查,监测其子宫动脉指标:收缩及舒张期峰值、阻力指数(RI)、波动指数(PI)及收缩期峰值/舒张期峰值(S/D),分析孕妇早、中孕期两期指标。同时分析不良妊娠结局发生的维、汉两民族孕妇,在早、中孕期子宫动脉血流参数的差异性。结果:孕妇子宫动脉在早孕及中孕期各项指标存在差异。不良妊娠结局发生的维、汉两民族孕妇,在早、中孕期子宫动脉血流参数的差异性无统计学意义(P>0.05)。结论:孕妇在孕期应分别在妊娠早期和中期测量其子宫动脉指标,贯续监测子宫动脉血流动力指标,对预测不良妊娠结局发生及母婴状况预测相对更准确、完善。在监测孕妇子宫动脉指标预测不良妊娠结局发生时,维汉两民族无明显差异。

Objective： By monitoring the indexes of uterine artery of pregnant women in the early and middle pregnancy,to study the differences of the uterine artery hemodynamic of Uighur and Han pregnant women at different gestational weeks and the differences of correlations of adverse pregnancy incidence and the uterine artery blood flow indexes. Methods： The uterine artery blood flow indexes of 202 Uighur and Han pregnant women in the early and middle pregnancy were monitored and analyzed by ultrasound,including systolic and diastolic peak,resistance index（ RI）,pulsatility index（ PI）,peak systolic/diastolic peak（ S/D）. Moreover,the incidence of adverse pregnancy and the differences of the uterine artery blood flow indexes of Uighur and Han pregnant women in the early and middle pregnancy were analyzed. Results： There were differences in the uterine artery blood flow indexes of the pregnant women in the early and middle pregnancy. There were no statistical differences in the incidence of adverse pregnancy and the uterine artery blood flow indexes between Uighur and Han pregnant women in the early and middle pregnancy. Conclusions： It should measure the indexes of the uterine artery in the early and middle pregnancy. It is more accurate and perfect to continuously monitor the hemodynamic indicators of the uterine artery to forecast the adverse pregnancy outcomes and the state of maternal and infants. There is no difference in the two nationalities when monitoring the uterine artery index to predict adverse pregnancy outcomes.
