以Low-Shear 3.0流变测定仪,据Huang的方程,用改良法测定20例青紫型先天性心脏病(CCHD)和30例非青紫型先天性心脏病(ACHD)患儿及相应健康对照组的全血触变参数,并进行比较。结果:ACHD组仅τ_0、η_、(η_s-μ)增高;CCHD组红细胞压积、τ_0、μ、A、η_s、(η_s-μ)明显增高,较健康对照组分别增加1.76、6.99、3.63、2.75、6.68及4.66倍,较ACHD组分别增加1.76、5.13、3.40、2.75、5.25及3.99倍。提示先天性心脏病(CHD)患儿全血触变参数可作为判断患儿病情及预后,为早期防治并发症提供理论依据。
Using Low-Shear 3.0 rheometer, according to Huang’s equation, 20 cases of cyanotic congenital heart disease (CCHD) and 30 cases of non-purple type of congenital heart disease (ACHD) were detected by modified method and the corresponding healthy control group Of whole blood thixotropic parameters, and compared. Results: In the ACHD group, only the values of τ_0, η_, (η_s-μ) increased; the hematocrit, τ_0, μ, A, η_s and η_s-μ of the CCHD group were significantly higher than those of the healthy control group by 1.76,6.99,3.63, 2.75, 6.68 and 4.66 times respectively, which were 1.76, 5.13, 3.40, 2.75, 5.25 and 3.99 times respectively higher than ACHD group. It is suggested that the parameters of whole blood thrombosis in children with congenital heart disease (CHD) can be used as a basis for judging the condition and prognosis of children and providing a theoretical basis for early prevention and treatment of complications.
