RESUMO
Objective:To explore the influencing factors and prevention and control measures of blood transfusion adverse reactions in patients with hematologic diseases.Methods:The clinical data of 988 patients with hematologic diseases requiring blood transfusion from January 2019 to December 2021 in Yongchuan Hospital Affiliated to Chongqing Medical University were retrospectively analyzed. The occurrence of blood transfusion adverse reactions in patients transfused with different blood preparations and different types of hematologic diseases was counted. Binary logistic regression was used for multivariate analysis to analyze the effects of gender, age, history of blood transfusion, history of allergy, primary blood disease, and type of blood transfusion on blood transfusion adverse reactions.Results:The 988 patients were transfused 4 712 times, and there were 62 times of blood transfusion adverse reactions, of which the incidence of allergic reactions was 53.2% (33/62), and that of non-hemolytic febrile transfusion reactions was 45.2% (28/62). A patient who presented with chest tightness and shortness of breath did not have a clear diagnosis of blood transfusion adverse reactions. Univariate analysis showed that blood transfusion history ( χ2 = 4.64, P = 0.031), allergic history ( χ2 = 700.07, P < 0.01) and type of blood transfusion ( χ2 = 19.88, P < 0.01) were all associated with blood transfusion adverse reactions. Multivariate logistic regression analysis showed that allergy history ( OR = 0.013, 95% CI 0.007-0.024, P < 0.001) and type of blood transfusion ( OR = 0.192, 95% CI 0.077-0.479, P < 0.001) were independent factors influencing the occurrence of blood transfusion adverse reactions. Conclusions:For patients with hematologic diseases requiring blood transfusion, strictly controlling transfusion indications, being alert to high-risk groups with a history of allergies requiring plasma and platelet transfusions, and taking countermeasures in advance can help reduce the occurrence of blood transfusion adverse reactions and improve transfusion safety.
