新生儿全血粘度与红细胞数量关系的分析

ANALYSIS OF THE RELATION BETWEEN THE WHOLE BLOOD VISCOSITY AND ERYTHROCYTE QUANTITY IN NEWBORNS

本文通过100例正常冬季出生的新生儿血流变测定,分析了红细胞压积与全血高切、低切粘度之间的关系,血红蛋白与红细胞压积之间的关系。资料表明它们呈直线相关。计算了红细胞压积与全血高切、低切粘度的相关系数、血红蛋白与红细胞压积之间相关系数并制定了相应的直线回归方程式。

In this article, hemorheological index have been determined for 100 normal newborns who werq born in the winter. The average value and standard deviations of the sample were showed respectivly in the follo- wing: Hb 17±2.5; hematocrit 54±4.35; whole blood high shear viscosity 6.94±1.25; whole blood low shear viscosity 11±2.92. The ralation bet- weep hematocrit and either whole blood high or low shear viscosity were respectively analysed by the determinate data, so was analysed the ralation between Hb and hematocrit. Through the right angled coordinate chart drawn, its clear that their relation is presented the linear corrala- tion. The correlation coefficient between newborn's hewatocrit and either whole blood high or low shear viscosity were r=0.77 (P<0.001) ; r=0.67 (P<0.001) respectively and r=0.62(P<0.001) between Hb and hematocrit. The linear regression equations of whole blood high or low shear visco- sity calculated by hematocrit were (?)=-9.26+0.3 x (P<0.001) ; (?)=-26.26+0.69x (P<0.001) respetively, and the one hematocrit calcula ted by Hb was (?)=35.1+1.112x (P<0.001).
