Analysis on the Factors affecting platelet transfusion efficacy / 国际检验医学杂志

ABSTRACT

Objective To investigate the factors affecting platelet transfusion efficiency.Methods A total of 102 cases of leuke-mia patients were recruited in the study,whose platelet count were measured before platelet transfusion and 1,24 h after platelet transfusion,then corrected count increment(CCI)values were calculated.By using CCI combined with clinical manifestations,the ef-ficacy of platelet transfusion were evaluated.The platelet antibody were detected before platelet transfusion.Depending on whether there were platelet antibodies,complications,the number of times of platelet transfusion,the types of platelet,patients were grouped and their platelet transfusion efficiency and CCI values were compared.Results The total effective rate of platelet transfusions were 71.6%(73/102 ).Invalid transfusion group had higher platelet antibody positive rate (17.2%)than effective transfusion group (2.7%),the difference were statistically significant(P <0.05).Among the groups of different transfusion times,the tansfusion effi-ciency was statistically different(P <0.05).With the increase of the number of times of platelet transfusion,the platelet transfusion efficiency decreased.Comparison between different types of platelets showed different platelet transfusion efficiency,which was sta-tistically significant(P <0.05).1 h and 24 h CCI value,platelet antibodies and whether patients with complications were related(P<0.05).1 h and 24 h CCI values were both associated with platelet antibodies and complications(P <0.05).Conclusion Platelet antibodies,complications,times of platelet transfusion and types of platelet transfusion are affecting factors of the transfusion effica-cy in patients with leukemia.
