目的：探讨临床应用单采血小板输注治疗的效果。方法选取308例单采血小板输注治疗患者，分析低频、中频、高频输注患者的有效率、不同病变患者输注情况以及输注频率与血小板输注有效率。结果输注次数增加时临床输注有效率下降，肿瘤、外科手术、其他病变患者进行血小板输注具有较高有效率，输注后lh、24h中PLT、CCI、PPR对比，三组差异均有统计学意义(<0.05)。结论对于血小板减少患者需要把握好输注最佳时间，严格把握输注指征，从而提高血小板输注治疗的效果。“,”Objective To investigate the clinical application of the treatment of single platelet transfusion.Methods 308 patients with single blood platelet transfusion were selected,the efficiency of the low frequency,intermediate frequency,high frequency infusion,the patients with different diseases,and the efficiency of platelet transfusion were analyzed.Results The number of clinical infusion decreased,and the tumor,surgical operation, other patients were treated with high efficiency,PLT,CCI,PPR,24h,LH,and the difference was statistically significant( <0.05).Conclusion It is effective to grasp the best time for the patients with thrombocytopenia,so as to improve the treatment effect of platelet transfusion.
