离子交换血是现代输血法中的新技术,它不需要防凝剂的参与就可制备不凝血,因之离子交换血的临床应用,便可免除枸橼酸钠对白细胞、红细胞及血小板形态和生理机能上的损害,可以免除因输枸橼酸血而引起的凝血机构紊乱。离子交换血是通过离子交换剂的作用,将部分钙离子脱除而获得,这样制备出来的血液,既可不凝又保存了血液的有形成分(白细胞、红细胞、血小板)生理功能的完整性。同时血内的激素及其他成分也很少遭到破坏。据苏联研究资料指出,离子交换血输入人体一个月之后,尚有50—57%的红细胞保存了完整的生活能力,这和直接输血所得到的结果完全一致,因而可以将这种血液用来代替操作困难的直接输血。
Ion exchange of blood is a new technology in modern blood transfusion, it does not require the participation of anticoagulants can be prepared without coagulation, the clinical application of ion exchange of blood, will be free of sodium citrate on white blood cells, red blood cells and platelet morphology and Physiological damage, can be removed due to lose citrate blood caused by coagulation disorders. Ion exchange of blood through the role of ion exchangers, the removal of part of the calcium obtained, so prepared blood, both non-condensable and preserved the physical components of the blood (white blood cells, red blood cells, platelets) the physiological function of the integrity. At the same time the blood hormone and other components are also rarely destroyed. According to the Soviet research data pointed out that ion exchange of blood into the human body a month later, there are still 50-57% of the red blood cells to save the full ability of life, and direct blood transfusion obtained exactly the same result, which can be used to replace this blood Difficult to operate direct transfusion.
