为了解血液流变学指标对预测妊高征的作用，对１２４例健康孕妇血液流变学指标从孕２０周开始进行连续动态观察。结果表明：１２４例预测对象中，发展为妊高征者２５例（２０．１６％），寒冷季节组发病率显著高于湿热季节组发病率（Ｐ＜０．０５）；寒冷季节组血粘度和红细胞压积值显著高于湿热季节组（Ｐ＜０．０５）；孕末期妊高征组血液流变学指标多项值高于正常妊娠组；孕中期血液浓缩者，后期发生妊高征的可能性较大。说明妊娠期血液浓缩在妊高征发病中有重要作用，寒冷季节可加重孕妇血液浓缩，应引起重视。
In order to understand the role of hemorrheology in predicting PIH, 124 hematological indexes of healthy pregnant women were continuously observed dynamically from the 20th week of pregnancy. The results showed that among 124 predictors, 25 cases (20.16%) developed PIH, the incidence in cold season group was significantly higher than that in warm and humid season group (P <0.05), while in cold season group, the blood viscosity And hematocrit values were significantly higher than those in the wet-heat season group (P <0.05). The multiple values of hemorrheological indexes in the end-stage pregnancy-induced hypertension group were higher than those in the normal pregnancy group. In the second trimester, The possibility of greater. Description of blood concentration in pregnancy in the pathogenesis of pregnancy-induced hypertension have an important role in the cold season can aggravate the blood concentration of pregnant women, should pay attention.
