妊高征（ＰＩＨ）是产科的严重并发症。ＰＩＨ的基本病理是全身小血管的痉挛，其血液动力学的表现为外周血管阻力增加，脏器灌流量下降。我们利用彩色多普勒血流显像技术观察了脐动脉（ＵｍＡ）血流参数的改变，结合红细胞压积测定及球结膜微循环的改变，探讨其相互之间的...
PIH is a serious obstetric complication. The basic pathology of PIH is systemic spasm of small blood vessels, whose hemodynamic manifestations include increased peripheral vascular resistance and decreased organ perfusion. We observed the change of umbilical artery (UmA) blood flow parameters by color Doppler flow imaging, combined with the hematocrit determination and the change of the conjunctival microcirculation, to explore their mutual ...
