Birthing backwards: unravelling trauma to move forward

Abstract

To determine the indication, efficacy and adverse events related to exchange transfusion (ET) with reconstituted blood (RB) in neonatal hyperbilirubinemia (NNH).Blood bank records of neonates who underwent double volume ET for NNH from January 2013 to July 2018 were retrospectively reviewed. Demographic details, cause of NNH, details of ET and ET related adverse events were recorded.A total of 23 ET (average: 1.64/neonate) were performed in 14 neonates (9 males; 5 females) with a mean age of 9.8 ± 7.6 days. Ten (71.4%) neonates underwent 1 session of ET, while 4 (28.6%) underwent repeated sessions (average: 3.25/neonate). A total of 5912 ml of RB was transfused (average: 422 ml/neonate). A statistically significant reduction was noted in total serum bilirubin (TSB) level post-ET (p < 0.001) with overall TSB reduction/procedure being 46%.Of the 14 neonates with NNH, 11 (78.6%) had Rh haemolytic disease of foetus and new-born (HDFN), 2 (14.3%) had ABO HDFN and 1 (7.1%) had hyperbilirubinemia due to prematurity. Of the 11 neonates with Rh HDFN, only 5 underwent intrauterine transfusion (average: 1.8/neonate).Post-ET, top-up transfusions were noted in 8 (57.1%) neonates with packed red blood cell and/or platelet concentrate. ET related adverse were noted in 5 (21.7%) procedures only.Rh HDFN was the most common cause of NNH in our study population.Exchange transfusion is a safe treatment modality for treating NNH, as it results in the rapid elimination of serum bilirubin, thus, lowering the risk of kernicterus in these patients.
