体外溶血试验配血救治急性溶血性贫血危象产妇的临床应用

本研究旨在建立体外溶血试验配血方法,指导急性溶血性贫血产妇输血的救治治疗.在体外将患者血浆中所有抗体全部致敏供者红细胞并加入补体,经6.5 h38℃孵育,观察是否出现溶血现象,不溶血的供血者的血液可以安全输注给受者.结果表明：患急性溶血病产妇配血困难时采用体外溶血试验方法筛查到相容供者,给予安全输注去白细胞的红细胞悬液6个单位,无不良反应,输血后患者血红蛋白、总胆红素、间接胆红质、网织红细胞、D-二聚体等指标迅速改善,临床输血治疗获得良好效果.结论：常规交叉配血无法准确判断配血结果是否相容时,采用体外溶血试验能筛查到凝集-不溶血红细胞,输血效果好,血红蛋白提升快,无不良反应.

Clinical Application of Blood Matching with Hemolgtic Test in Vitro for Transfusion Treatment of Crisis Puerpera with Acute Hemolytic Anemia

This study was aimed to establish the matching method of hemolytic test in vitro, and to guide the transfusion treatment for puerpera with acute hemolytic disease. The donor＇s erythrocytes were sensibilized by all the antibodies in plasma of patient in vitro and were added with complement, after incubation for 6.5 hours at 38 ∽（2, the hemolysis or no hemalysis were observed. It is safe to transfuse if the hemolysis did not occur. The results showed that when the matching difficulty happened to puerpera with acute hemolytic disease, the compatible donor could be screened by hemolytic test in vitro. There were no untoward effects after transfusion of 6 U leukocyte-depleted erythrocyte suspension. The all hemoglobin, total bilirubins, indirect bilirubin, reticulocyte, D-dimex and so on were rapidly improved in patient after transfusion , showing obvious clinical effecacy of treatment. It is concluded that when the matching results can not judge accuratly compatible or incompatible through the routine method of cross matching, the agglutinated and no-hemolytic erythrocytes can be screened by hemolytic test in vitro and can be transfused with good efficacy; the hemoglobin level can be promoted rapidly, and no untoward effects occur .
