title: [Analysis on effectiveness of platelet transfusion in 1786 patients].
abstract: This study was aimed to observe and analyze the effectiveness of platelet transfusion. The platelet count of 1786 patients before transfusion and on 20-24 hours after transfusion was determined by using Auto-Hematology Analyzer, the percent platelet recovery (PPR) was calculated, the platelet transfusion efficiency (PTE) was evaluated by PPR and hemorrhage presentation after platelet transfusion, and the PTE was statistically analyzed according to disease cause, transfusion frequency, platelet type and once transfusion amount. The results showed that the total PTE of 1786 patients was 52.5%. The comparison of PTE among groups of disease cause showed that PTE in leukemia and aplastic anemia (AA) was lowest, as compared with that of other diseases (P < 0.05), while PTE in operation group was highest. The comparison of PTE among groups of transfusion frequency revealed also statistical difference (P < 0.01), meanwhile PTE decreased with increasing of transfusion frequency. The comparison of PTE among groups of platelet type (platelet phoresis or platelet concentrate) showed statistical difference (P < 0.01). The comparison of PTE among groups of platelet concentrate of once transfusion amount showed no statistical difference (P > 0.05). It is concluded that the PTE closely relates with disease cause of patients, moreover transfusion frequency also associates with PTE, the more frequency of transfusion, the higher possibility of transfusion refractoriness. The PTE of platelet pheresis is obviously superior to that of platelet concentrate, while PTE of platelet concentrate not significantly relates with once adequate or not.
