Dedicated donor unit transfusions reduces donor exposure in pediatric surgery patients

Many strategies have been explored to reduce multiple donor exposures in neonates such as use of restrictive transfusion protocols, limiting iatrogenic blood loss, use of recombinant erythropoietin and single donor programs.

In our study we assessed the feasibility of dedicating single donor units with reserving all the components from the same donor for the specified neonates/infants undergoing surgery and estimating reduction of donor exposure. Fifty neonates undergoing surgery were included in the prospective study group and the transfusion details were compared with 50 retrospective cases with same inclusion criteria.

An intra-operative blood loss of >13 ml/Kg was significantly associated with transfusion (P <0.05) which was most frequently administered in the intra-operative period. Donor exposure rate of overall transfusion was 1.15 in the study group as compared to 4.03 in the retrospective control group. In study group Donor Exposure Rate (DER): Transfusion Rate (TR) ratio was 1:1.5 and Transfusion per Donor Unit (TPDU) of 1.5, means that one donor unit contributed to 1.5 transfusions in each patient and contributed to 50% reduction in donor exposure in each patient as compared to retrospective control group.

Our study showed that by practicing dedicated donor unit transfusion policy, for neonates undergoing surgery we could significantly reduce the donor exposure.
