目的：监测妊高征孕妇血液流变学各值，对比与胎儿升主动脉平均血流速度（Ｖｍ）的相关性及对围产儿结局的影响。方法：用粘度仪测妊高征孕妇血液流变学各值，包括：全血比粘度高切（ＢＶＨ）、全血比粘度低切（ＢＶＬ）、全血还原比粘度、血浆粘度（ＰＶ），用离心机测红细胞压积（ＨＣＴ）、纤维蛋白原（Ｆｉｂ）；用彩色多普勒计测胎儿升主动脉平均血流速度（Ｖｍ）。结果：妊高征孕妇血液流变学各值与胎儿升主动脉血流Ｖｍ呈正相关性（Ｐ＜０．０１、Ｐ＜０．００１）、当血液流变学：ＨＣＴ≥０．３６、ＢＶＨ≥４．６、ＢＶＬ≥６．２３、ＰＶ≥１．６３、胎儿升主动脉Ｖｍ≥３４ｃｍ／ｓ时，提示妊高征的发生和胎儿宫内缺氧，此值可作为临界值，预测胎儿窘迫；当血液流变学各值：ＨＣＴ≥０．４１、ＢＶＨ≥５．２７、ＢＶＬ≥７．４、ＰＶ≥１．７５、胎儿升主动脉Ｖｍ≥５４．７８ｃｍ／ｓ时，提示妊高征病情严重，胎儿缺氧酸中毒，围产儿预后不良，此值可作为危险值，指导临床处理。结论：监测妊高征血液流变学各值和胎儿升主动脉血流Ｖｍ，综合分析，可提高预测妊高征发生、发展及严重程度和对围产儿预后的影响，可及时发现异常，及时处理，降低围产儿病残率和死亡率，对保障母儿健康、优生?
Objective: To monitor the value of hemorheology in pregnant women with PIH and to compare with the correlation between the mean blood flow velocity (Vm) of fetal ascending aorta and the effect on perinatal outcome. Methods: The blood rheology values of pregnant women with PIH were measured by viscometer, including BVH, BVL, whole blood reduction specific viscosity, plasma viscosity (PV) (HCT) and fibrinogen (Fib) were detected by centrifuge. The average blood flow velocity (Vm) of fetal ascending aorta was measured by color Doppler. Results: There was a positive correlation between hemorrheology and Vm of ascending aorta (P <0.01, P <0.001). When hemorheology: HCT≥0.36, BVH ≥ 4.6, BVL ≥ 6.23, PV ≥ 1.63, fetal ascending aorta Vm ≥ 34cm / s, suggesting the occurrence of pregnancy-induced hypertension and intrauterine hypoxia, this value can be used as a critical value to predict fetal Distress; when the values of hemorheology: HCT≥0.41, BVH≥5.27, BVL≥7.4, PV≥1.75, fetus ascending aorta Vm≥54.78cm / s, Sign of a serious condition, fetal hypoxic acidosis, perinatal poor prognosis, this value can be used as a dangerous value, to guide clinical treatment. CONCLUSIONS: To monitor the values of hemorheology of pregnancy induced hypertension and Vm of fetal ascending aorta, we can predict the occurrence, development and severity of PIH and prognosis of perinatal children by comprehensive analysis. We can detect abnormalities and timely Treatment, reduce perinatal morbidity and mortality, to protect the health of mothers, eugenics?
