胎儿宫内生长迟缓孕妇的血液流变性及其意义

本文分析了117例并发IUGR孕妇和54例正常孕妇的血液流变性,研究孕妇血液流变性与胎儿生长发育及母婴预后的关系。结果显示:并发IUGR孕妇血液流变性减退,表现为全血比粘度高切、低切,血浆比粘度和红细胞压积增高;与单纯并发IUGR孕妇相比,IUGR与妊高征和/或肝损同时存在时,血液汽变性减退更加显著。血粘度增高而扩容治疗无效(即血液流变性持续减退)的Ⅰ.UGR孕妇肝损和早产的发病率显著增高。这些母亲所生新生儿并发症增多,出生体重减轻。我们还发现,新生儿出生体重与母亲血液流变性有显著关系,出生体重与孕妇全血比粘度高切、红细胞压积呈负相关,而与孕周呈正相关。我们认为,孕妇血液流变性与胎儿生长发育有密切关系,显著影响着妊高征、IUGR和肝损的发生发展。扩容治疗可改善血液流变性,减少母婴并发症,降低围产期发病率和死亡率。

Significance of Hemorheology in Women with IUGR

Hemorheology of 117 women with IUGR and 54 subjects in normal pregnancy was analyzed in current study. It was found that blood was concentrated, viscosity was increased in women with IUGR. This was even more significant when accorapaaied with pregnancy induced hypertention and liver diseases. Women with IUGR had higher rate ot premature labour and liver disease if their blood viscosity remained abnormal. The weight of newborn was related negatively to blood viscosity and hematocrit, but positively to gestational age significantly. It was indicated that maternal hemorheology had effect on the development of IUGR and outcome of pregnancy.
