健康新生儿脐血血液流变学观察及分析

ABSTRACT OF ORIGINAL ARTICLE OBSERVATION AND ANALYSIS OF HEMORRHEOLOGY IN HEALTHY NEONATAL UMBILICAL BLOOD

本文报道了天津市健康新生儿脐血八项血液流变学指标的正常参考值。并将此值与健康成人正常值做比较，发现新生儿血液粘度高于成人。新生儿血液粘度增高的主要原因是由于血球压积较高，红细胞变形性较低而聚集性较高。了解新生儿血液流变学特点对指导临床有重要意义。

The article reports the normal values of eight targets of hemorrheology in healthy neonatal umbilical blood in Tianjin. As the eight targets normal values have been campared with hemorrheological normal values of adult. We discover that neonatal viscosity of blood is higher than the viscosity oF blood of adult. The main reasons of the increase in neonatal viscosity of blood are that hematocrit is higher,deformation of RBC is lower and aggregation of RBC is higher in newborn. It is significative for guiding clinic to understand neonatal hemorrheological characteristics
