correct answer
d Faster time to achieve balanced resuscitation
The study by McLoughlin et al. (2024) found that whole blood (WB) significantly improved the time to balanced resuscitation in critically injured preadolescent children compared to component therapy (CT). In trauma situations, "balanced resuscitation" refers to replacing blood lost from hemorrhage with equivalent blood components (red blood cells, plasma, and platelets).
Traditionally, CT has been used to achieve this balance, requiring separate transfusions of each blood component. However, this process often takes longer to administer, which can delay stabilization efforts in time-sensitive situations. In this study, WB achieved balanced resuscitation in a median time of 28 minutes, compared to 87 minutes with CT, highlighting WB’s efficiency in delivering all necessary components in one transfusion.
WB was also associated with fewer transfusion exposures, which is important for minimizing risks associated with multiple donor exposures, such as infections and alloimmunization. Additionally, WB yielded a lower total volume of transfusion (50 mL/kg compared to 85 mL/kg in CT), which may reduce the risk of transfusion-related complications in children, whose smaller circulatory volumes make them more vulnerable to fluid overload. While the study found no statistically significant difference in overall hospital mortality between the WB and CT groups, the reduction in resuscitation time, transfusion exposures, and blood volume requirements suggests that WB offers key logistical and clinical benefits, supporting its use as a valuable option in pediatric trauma resuscitation.
