Outcome of infants receiving in-utero transfusions for haemolytic disease

Abstract

Aims. To review the outcome of infants who received inutero transfusion (IUT) at National Women's Hospital (NWH). Specifically to determine postnatal exchange and top-up transfusion requirements, to examine perinatal factors useful for predicting this and review neurodevelopmental status of recipients. Methods. A review was undertaken of infants delivered at NWH between 1991 and 2000, who had received one or more IUT for haemolytic disease. The mean gestational age at birth was 34 weeks and birth weight 2298 g. The median number of IUT was four (range 1-9). The mean gestational age at the first IUT was 25 weeks and at last IUT was 31 weeks. Results. All 37 infants survived to discharge. Postnatal exchange transfusion was required in ten and top up transfusion in 27 infants. Late transfusion (>3 weeks) was required in 271 infants. Follow-up information on 36 infants revealed one born prematurely following death of a co-twin had cerebral palsy and developmental delay. No other infant had audiology or neurodevelopmental abnormality. Conclusions. This review helps to confirm the good outcome following IUT although some infants continue to require transfusions for up to four months after birth.
