Abstract
Objective The objective of this study was to determine whether packed red blood cell (pRBC)
transfusions in extremely low birth weight (ELBW) infants were associated with acute
respiratory decompensation (ARD).
Study Design Retrospective chart review of ELBW infant pRBC transfusions analyzed for meeting
ARD criteria during the 6 hours post-pRBC transfusion was compared with the pretransfusion
baseline period. A control period subdivided into similar pre- and postintervals was
also assessed for each infant. ARD was defined as ≥ 1 of the following: (1) ≥ 10%
increase in fraction of inspired oxygen from highest baseline, (2) ≥ 2 cm H2O increase from highest baseline in mean airway pressure, or (3) escalation in mode
of respiratory support.
Results A total of 238 pRBC transfusions occurred in 36 ELBW infants during 2012. Complete
data for both the transfusion and control time periods existed for 110 pRBC transfusions
(25 infants) and were included for analysis. The frequency of ARD was 15.5 and 18.2%
(odds ratio, 1.25; p = 0.70) in the control and transfusion time periods, respectively.
Conclusion pRBC transfusions in ELBW neonates are not associated with statistically significant
rates of ARD compared with nontransfusion control time periods.
