Abstract:
【Objective】 To compare the efficacy and safety of transfusion of suspended RBCs and washed RBCs in patients with positive direct Coombs testing results. 【Methods】 A retrospective analysis was conducted on 98 patients with positive direct Coombs testing results as 2+ or less in the First Affiliated Hospital of Chongqing Medical University from January 2015 to December 2020. Among them, 31 patients, from January 2015 to December 2016, were transfused with washed RBCs and set as the control group; the other 67 patients, from January 2017 to December 2020, transfused with suspended RBCs, were enrolled as the experimental group. The changes of main laboratory indexes and the incidence of transfusion adverse reactions before and after transfusion of 2 U and 4 U RBCs were compared between the two groups to evaluate the efficacy and safety of transfusion. 【Results】 After 2 U and 4 U transfusion, Hb increased by 12±4.967 (g/L) and 23.78±12.736 (g/L) in the control group, while 12.85±7.109 (g/L) and 22.68±9.832 (g/L) in the experimental group, All transfusions of the two groups were effective, and no significant differences in Hb, TBIL, IBIL and LDH were noticed by groups (P>0.05). No significant difference in the incidence of adverse reactions to blood transfusion between the 2 groups was observed (P>0.05). 【Conclusion】 The transfusion of suspended RBCs is safe and effective in patients with positive direct Coombs testing results as 2+ or less, and the transfusion of washed RBCs was unnecessary.
