一、溶血性贫血的概念红细胞生存期短于100～120天而溶解破坏者称之为溶血。溶血程度超出骨髓代偿功能,血红蛋白不能达到11～12g/dl者称为溶血性贫血。二、溶血综合征红细胞破坏增加出现溶血时必有如下三个方面的改变:(一)有血红蛋白代谢过盛有关的症侯:1.血浆中胆红素含量增高,且以非结合型胆红素为主,超过2mg/dl时可出现黄疸,慢性者可合并胆石症。2.血浆结合珠蛋白(a_2球蛋白)明显减少(正常为70～150mg/dl),血浆中 First, the concept of hemolytic anemia Erythrocyte survival is shorter than 100 to 120 days and dissolve the destruction of those who call it hemolysis. Hemolysis beyond the compensatory function of bone marrow, hemoglobin can not reach 11 ~ 12g / dl known as hemolytic anemia. Second, the hemolytic syndrome Red blood cell damage increased hemolytic must have the following three aspects of change: (a) hemoglobin metabolism over the relevant symptoms: 1. Plasma bilirubin levels increased, and to non-conjugated bile red Su-based, more than 2mg / dl jaundice can occur, chronic cholelithiasis can be combined. 2. Plasma haptoglobin (a 2 globulin) was significantly reduced (normal 70 ~ 150mg / dl), plasma
