摘要 目的 运用彩色多普勒超声序贯监测妊娠早、中和晚期子宫动脉血流特征并制定各个孕期相应的参考值。方法 2005-04—2006-04随机对南京医科大学第一附属医院妇产科160例妊娠妇女通过彩色多普勒超声在孕10—14用、20~24用、30—34用以及50例非妊娠期妇女序贯监测子宫动脉血流动力学3项参数[S/D(收缩期峰值流速/舒张末期流速)、PI(搏动指数)和RI(阻力指数)]。结果 (1)妊娠期血流动力学3项参数与非妊娠期相比显著性降低(P〈0.01),并随孕周增加逐渐降低,不同孕期之间差异均有显著性(P〈0.01)。(2)不同孕周的3项参数均为正态分布。其参考值范围(双侧95%的界限值)分别为:早孕期:RI(0.73±0.16)、PI(1.66±0、86)、S/D(4、12±2.69);中孕期RI(0.56±0、16)、PI(0.94±0、47)、S/D(2.36±1.06);晚孕期RI(0.51±0.18)、PI(0.82±0.45)、S/D(2.13±1.02)。结论 随着妊娠进展,子宫动脉血流动力学3项参数逐渐降低。深入讨论这些参数的参考值范围有助于准确、全面地评估妊娠状态和预测妊娠结局。
