摘要 目的了解并比较机器单采浓缩血小板(简称单采血小板)和手工分离浓缩血小板(简称手工血小板)对免疫性血小板减少症(immune thrombocytopenia,ITP)的治疗效果。方法 2005年1月至2012年12月在四川大学华西第二医院儿科住院符合ITP诊断并输注血小板制品的338例ITP患儿为研究对象。其中输注机器单采血小板患儿251例次为单采制剂组(简称为单采组),输注手工分离血小板制剂患儿87例次为手工制剂组(简称为手采组)。分别在输注后24 h计算血小板计数增加校正指数(CCI)、血小板回升率(PPR)、输注无效率、输注后患儿血小板数值达到≥30×109/L,60×109/L,100×109/L的时间等指标。结果输注24 h后,单采组CCI为23.4,PPR为51%,手采组CCI为24.5,PPR为48.3%,差异无统计学意义。单采组输注无效率为12.7%,明显低于手采组输注无效率22.9%。单采组输注后,患儿血小板数值达到≥30×109/L,60×109/L的中位时间分别为23 h和44.5 h,手采组分别为20 h和48.7 h时,两组差异无统计学意义(P>0.1)。单采组患儿血小板≥100×109/L的中位时间为54 h,手采组为62 h,单采组明显低于手采组(P<0.05)。结论输注单采血小板及手采血小板均能有效提高ITP患儿外周血血小板数值,但输注单采血小板制剂的效果更好。
