目的观察特殊情况紧急抢救输ABO血型不合的血小板效果,分析供受者ABO血型不合时血小板输注的可行性。方法 ABO血型不合血小板输注156例,计算输注后24 h的血小板计数增加指数(CCI),并与同期ABO相合的血小板输注235例的结果比较,统计分析CCI与ABO配型的关系。结果特殊情况紧急抢救输ABO血型不合的血小板未见临床不良反应,但疗效低于ABO同型输注。结论一般输血小板要求ABO同型,但特殊情况为了抢救患者生命,可以输注ABO异型血小板。
Objective To observe the special circumstances of emergency rescue ABO incompatible platelet transfusion efficacy, analysis of donor ABO incompatible platelet transfusion feasibility. Methods 156 patients with ABO incompatible platelet transfusion were enrolled in this study. The index of increase of platelet count (CCI) at 24 h after transfusion was calculated and compared with the result of platelet transfusion combined with ABO at the same period. The relationship between CCI and ABO typing was statistically analyzed. Results Special cases of emergency rescue lose ABO incompatible blood platelets no clinical adverse reactions, but the efficacy is lower than ABO same type of infusion. Conclusion General platelet transfusion requires ABO isotype, but special circumstances in order to save the lives of patients, can be infused ABO atypical platelets.
