彩色多普勒监测妊高征孕妇子宫胎盘血流变化

应用彩色多普勒血流显像技术监测了３１例妊高征孕妇及７４例正常孕妇子宫胎盘血流，同时测定血中雌三醇、胎盘泌乳素、血栓素代谢产物、前列环素代谢产物及ＴＸＢ２／６ＫＰ比值。结果表明：正常孕妇子宫动脉及胎儿脐动脉的时间平均血流速度及血流量明显高于妊高征孕妇。

Uteroplacental bolld flow monitoring by color Doppler flow imaging in pregnancy induced hypertension

he uteroplacental blood flow was monitored using color Doppler flow imaging(CDFI)in 31 cases of pregnancy induced hypertension(PIH)and 71 cases of normal pregnancy. At the same time the values of serum estriol(E_3),human placental lactogen (hPL), thromboxane(TXB_2),6-KP and TXB_2/6-KP ratio were measured. The results showed that time average velocity(TAV)and voiume of blood flow(Q)of uterine and umbilical arteries in PIH cases were much lower than those in normal pregnant women and fetuses(P< 0. 05 ).After treatment with magnesium sulfate and qingxintong there was a marked improvement in placental blood flow. TAV and Q of uterine and umbilical arteries was also in-creased(P<0. 05).In PIH cases the E_3 and hPL levels were much lower,while the ratio ofTXB_2/6-KP was significantly higher than that in normal pregnancy,Using CDFI to observe the velocity and vol-ume of uteroplacental blood flow can monitor the blood supply of uterus and placenta. It is a valuable predictive index of fetal and placental function.
