Blood transfusion in newborn.

ABSTRACT

Premature infants are among the most frequently transfused groups of patients, usually receiving red cells. The immaturity of the immune system, its lesser ability to cope with a metabolic load and the presence of maternal antibodies, all complicate the picture. Conservation of blood to minimize losses and the need for replacement transfusion is an important strategy that has already been successful in reducing the need for transfusion on neonatal units. The advent of erythropoietin provides another strategy for reducing the need for transfusion. It is unfortunate that the sickest patients who require the most transfusion poorly respond to erythropoietin. Main concern is the long-term consequences of transfusion. Presently the aim is to minimize transfusion risks and give transfusions only when they are indicated.
