RESUMEN
AIM: To describe neonatal outcomes following intrauterine transfusion (IUT) for severe Rhesus isoimmunisation from 1993 to 2004. RESULTS: 116 neonates who had undergone 457 IUTs (median 4, range 1-9) were identified. Three neonates died, all before 1995 (two because of hypoxic ischaemic multiorgan failure and one because of overwhelming Escherichia coli sepsis). 13 neonates (11%) were delivered by emergency Caesarean section following either IUT complication or spontaneous onset of preterm labour. They were more likely to require intubation (p<0.0001), on-going respiratory support (p=0.0007) and an exchange transfusion (p=0.007). 23 (20%) required an exchange transfusion and 63 (54%) at least one top-up transfusion. CONCLUSIONS: Management of severe Rhesus disease is associated with encouraging neonatal outcomes and most infants can be managed with phototherapy and a few top-up transfusions. IUT complications are rare but significantly increase neonatal mortality and morbidity. Antenatal counselling should address the likely postnatal course for these infants.
