Analysis of Factors Influencing the Effect of Red Blood Cell Suspension Infusion in Children

Objective: The related factors of no improvement of hypoxia and ineffective infusion were analyzed to provide new ideas, clinical observation and evaluation pathway for RBC transfusion in clinical children. Methods: Retrospective analysis from January 2020 to December 2020, Guangzhou women and children’s medical center hospital in the emergency observation room of 249 children under 1 month to 18 years of blood cell suspension infusion, analyze the clinical effect of red blood cell infusion and children gender, age, fever after transfusion, disease type, delay transfusion. The possible influencing factors were analyzed by logistic regression. Results: Invalid transfusion was associated with the type of transfusion product (P = 0.032), logistic regression analysis showed that patients infused with washed RBC suspension were 3.231 times more likely to not achieve the expected effect than those infused with RBC suspension (P = 0.025). Failure transfusion was associated with the type of transfusion products. In ineffective transfusion was closely related to post-transfusion fever (P < 0.001). Logistic regression analysis showed that post transfusion fever was a risk factor for ineffective red blood cell transfusion (OR = 9.026, P < 0.001). The improvement of hypoxia after transfusion in children was related to fever, age, sex and transfusion time. Compared with male children, female children are more likely to have no improvement in hypoxia after blood transfusion (P = 0.031). Logistic regression analysis showed that fever after transfusion was a risk factor for no improvement of hypoxia (OR = 5.809, P = 0.001), and the improvement of hypoxia in adolescent children was 10.744 times higher than that of infants (0 - 3 years old). Late transfusion hypoxia improvement was 4.212 times more likely to achieve no effect than timely transfusion. If ineffective infusion of red blood cells is considered and hypoxia after transfusion is not improved, univariate suggests a close correlation with fever after transfusion (P = 0.002), logistic regression analysis showed that fever after transfusion was an independent risk factor (OR = 7.258, P = 0.002). Conclusion: There was no correlation between the ineffective transfusion of red blood cells and the type of disease affected in the child. Infusion of red cell suspension has an advantage over the wash red cell infusion. Ineffective RBC transfusion and no improvement in hypoxia after transfusion were closely related to post-transfusion fever, with no difference between children in all age groups. Red blood cell infusion in pediatric clinical treatment activities should pay attention to adolescent children, especially female children to give more attention, and give timely red blood cell infusion as much as possible.
