[Analysis on the effectiveness in 727 times of platelet transfusion]

This study was purposed to analyze the efficiency of platelet transfusion and to explore factors influencing platelet transfusion efficiency. 727 times of platelets transfusion in 254 patients in The Third Xiangya Hospital from September 2010 to May 2011 were analyzed retrospectively. Moreover, according to symptoms, times of platelet transfusion, blood types and splenomegaly, the corrected count of increment (CCI) and percentage of platelet recovery (PPR) were calculated for evaluation of platelet transfusion efficiency. The results showed that there were 456 effective transfusions out of 727 transfusions (62.72). Among them, the therapeutic effect of platelet transfusion for patients with acute blood loss anemia and chronic systemic diseases was relatively obvious, specially for chronic renal disease, the effective efficiency of them was 94.12. The patients with splenomegaly showed a significant impact on platelet transfusion efficiency (41.07). Analysis found that the frequency of platelet transfusion negatively correlated with transfusion efficiency. It is concluded that the transfusion frequency and splenomegaly are factors influencing the transfusion efficiency.
