血小板膜糖蛋白的表达变化是反映血小板激活程度分子水平的敏感而特异的指标[1],血小板灭活是婴幼儿先天性心脏病体外循环心肺转流(CPB)手术中和手术后出血的重要因素[2]。在CPB中循环血小板有功能和结构改变[3],血小板被激活,血小板膜糖蛋白Ib的表达减少。小儿CPB时循环血量相
Changes in platelet membrane glycoprotein is a sensitive and specific indicator of the level of platelet activation [1], platelet inactivation of infants with congenital heart disease in cardiopulmonary bypass cardiopulmonary bypass (CPB) surgery and postoperative bleeding is important Factors [2]. Circulating platelets in CPB function and structural changes [3], platelets are activated, the expression of platelet membrane glycoprotein Ib decreased. Circulating blood volume in children with CPB
