[Association of ABO Blood Group with Plasma Transfusion Volume and the Related Clinical Influencing Factors].

OBJECTIVE

To investigate the differences in plasma transfusion volume among patients with different ABO blood types, and to evaluate the predictive value of relevant clinical indicators such as platelet count (PLT) and other laboratory indicators for the plasma transfusion requirements.

METHODS

A single-center retrospective cohort study was conducted including 154 hospitalized patients who received plasma transfusions between January 2022 to December 2023. Patients were grouped by ABO blood group, plasma transfusion volumes and laboratory parameters were compared, and multivariate linear regression was used to identify independent predictors.

RESULTS

There was no statistically significant difference in the plasma transfusion volume among patients with different ABO blood types (P>0.05). PLT was significantly negatively correlated with the plasma transfusion volume (r=-0.963, P<0.001), and it was the only statistically significant independent factor in the multiple linear regression analysis.(β=-0.961, P<0.001).

CONCLUSION

There is no significant correlation between ABO blood group and plasma transfusion volume. Platelet count is an independent indicator for predicting plasma transfusion volume, providing a new perspective and practical value for precise blood transfusion management.
