Abstract: Objective To analyze the effect of RBC transfusion of different ABO types,and the practicability of “Recommended Program of Emergent Blood Transfusion”.Methods A retrospective study of RBC transfusions of different blood typesinpatients was performed and compared with the patients with the same blood type RBC transfusions.Results The samples included 32 cases of autoimmune hemolytic anemia(AHA) with 52 transfusions and 7 cases of leukemia with 12 transfusions. No significant difference was noted among the patients with AHA who received same type suspended or washedRBCs,or O type washed RBCs.Conclusion The same type suspended RBCs may be used at emergency for patients with autoimmune hemolytic anemia whereas O type washed RBCs are recommended primarily for those with leukemia. For the patients whose blood type has been identified,suspended RBCs of the same type blood may be used for transfusion.“Recommended Program of Emergent Blood Transfusion” is instructive although it remains to be improved.
