| 摘 要： | 超声测量168例孕20~26周正常胎儿脐带胎盘插入点、距脐孔50 mm 范围内游离段、腹内段3处的脐静脉血流量(QPI、QFL、 QIA)以及左门静脉血流量( QLPV),计算QLPV/ QIA,拟合 QPI 及 QIA 随孕周增长的回归方程,比较QPI 和 QIA、QFL 和 QIA。 QLPV/ QIA 在恒定范围内,95%参考值范围：0．42~0．58；QPI 及 QIA 与孕周的增长呈直线关系,回归方程：(QPI：^Y =21．25X -385．92,R2=0．970；QIA：^Y=17．26X -314．75,R2=0．954)；QPI 和 QIA 比较差异有统计学意义(P <0．05),QFL 和 QIA 比较差异无统计学意义。

| Abstract: | 168 fetuses were measured from uncomplicated singleton pregnancies at 20 ~ 26 weeks of gestation. The umbilical vein blood flow obtained at placental insertion, free loop and intra - abdominal portion ( QPI, QFL, QIA) and right portal vein blood flow(QLPV) were measured respectively by doppler ultrasound. QLPV/ QIA was calculated. QLPV/ QIA was in constant range:0. 42 ~ 0. 58. There was a linear relationship between QPI and QIA and growth of gestational age. The regression equation was:(QPI:^Y = 21. 25X - 385. 92, R2 = 0. 970; QIA:^Y =17. 26X - 314. 75, R2 = 0. 954). QPI and QIA were statistically significant (P < 0. 05). QFL and QIA were simi-lar. |
