For what reason might a doctor's choice of product for transfusion differ in neonates as compared to adults?

The reasoning behind the choice of blood products for transfusion in neonates compared to adults centers around unique physiological considerations. Neonates, particularly premature infants or those with low birth weight, have smaller blood volumes and are at a much higher risk of volume overload. This risk necessitates a cautious approach to transfusions, meaning that products must be modified to ensure that they meet the specific needs of this vulnerable population.

For example, red blood cell transfusions for neonates are often leukoreduced (white blood cells are removed) to decrease the risk of transfusion-related complications, including febrile reactions and potential infection. Moreover, the blood volume in neonates is significantly less than in adults, and transfusions must be carefully dosed to avoid exceeding their limited volume capacity.

This adaptation in practice is not as prominent in adults, who can receive standard blood products without the need for such modifications to address volume or size concerns. Therefore, the focus on specific modifications for neonates directly addresses the risks associated with their smaller size and unique physiological responses, making it essential to tailor transfusion practices accordingly.
