摘　　要：胎儿宫内安危是关系到围产儿病残率及死亡率的重要因素，产前预测妊高征的发生及其对围产儿的影响，是围产医学急待解决的重要课题。本研究运用彩色多普勒计测轻、中、重度妊高征胎儿脐动脉血流Ｓ／Ｄ、ＰＩ、ＲＩ值和平均血流速度（Ｖｍ）的平均值，对比三组妊高征孕妇血液流变学：红细胞压积（ＨＣＴ）、全血比粘度高切（ＢＨＶ）、全血比粘变低切（ＢＶＬ）、血浆粘度（ＰＶ）等与脐动脉Ｖｍ的相关性。结果表明妊高征孕妇血液流变学各值与脐动脉Ｖｍ呈负相关性。孕妇血液流变学各值越增高，Ｖｍ越降低，围产儿结局不良的发生率增高，胎儿脐动脉Ｖｍ≤２８ｃｍ／ｓ时提示胎儿－胎盘循环障碍，胎儿窘迫发生，预测妊高征的严重程度和胎儿宫内安危状况，对提高围产医学质量、保障母婴健康、优生有良好作用。Whether or not the fetus is safe in the uterus is the important factor which is relative to the death rate and the crippled rate.It is urged to solve for the perinatology that we predict the occurence of pregnance induced hypertension(PIH)and its affect to the perinatal fetus.This research applys color Doppler ultrasonography to monitor the umbilical arterial blood flwo S/D,PI,RI and the mean velocity(Vm) of the fetus of the low,middle and high PIH.Comparing the hemoheologys(HCT,BVH,BVL,PV)of the three kinds of PIH pregnant women with the umbilical arterial Vm can conclude the negative relativity between hemoheology of pregnant wowen with PIH and umbilical arterial Vm.The higher the reference of hemoheology of pregnant women is the lower the umbilical arterial Vm of the fetus,and the more often the bad result occurs.When the umbilical arterial Vm≤28cm/s,it shows that the placenta circulation blocking and the fetal distress occur.It can increase the quality of perinatology,protect the pregnant women and fetal health and be good for the well born by predicting the severity of the PIH.
