血液流变学指标预测妊高征的研究

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。

A Study of Hemorheological Indexes Predicting Pregnancy Induced Hypertension

? To investigate whether hemorheological indexes predicting pregnancy induced hypertension(PIH). 124 cases of healthy primigravidae were studied continuously. The results showed that there were 25 cases of pregnancy subsequent developing PIH(20.16%). The incidence of PIH and the values of the whole blood viscosity and the hematocrit were higher in the cold weather group(from Nov to Mar) than in the hot weather group(from May to Sep, P<0.05). The values of the most hemorheological indexes were higher in subsequent developing PIH than in normotensive pregnancy. The hemorheological indexes in pregnancy of mid trimester had negative predictive values and sensitivities. It indicated that hemoconcentration played important role in the pathogenisis of PIH. 
