To determine whether platelet infusion time affects platelet counts in thrombocytopenic newborns.STUDY DESIGN:
This was a prospective randomized control study of 43 platelet transfusions given to newborns. Transfusions were randomized to run over either 30 min or 2 h. Platelet counts taken 30 min and 6 h after transfusion were compared using parametric, nonparametric, Pearson's correlation and logistic regression.RESULT:
Changes in platelet counts 30 min and 6 h after transfusion were not different between the groups. Weak but significant negative correlations existed between postmenstrual age and change in platelet count at 30min (r = −0.33, P = 0.04) and 6h (r = − 0.37, P = 0.018) after transfusion. There were no differences between the mean blood pressures before and after transfusion in either group.CONCLUSION:
Transfusion duration does not affect post-transfusion platelet counts in newborns. Babies of lower postmenstrual age (PMA) may have better responses to platelet transfusions. Finally, platelet transfusions over both durations are well tolerated in neonates.
