Clinical Study of Combined Platelet Transfusion

Combined platelet transfusion is a single-arm, open, prospective, non-inferiority study initiated by researchers. Patients with hematological diseases who were admitted to the research unit and applied for platelet transfusion within two years were included in the study after informed consent. When the subjects applied for platelet transfusion during the study period, ABO homotype platelet transfusion was preferred. When there was no ABO homotype platelet in the inventory, ABO primary and secondary side compatible combined platelet transfusion was given. The study period was 2 years, including 15 months of enrollment, 6 months of treatment, and 3 months of follow-up after the end of the treatment period
