There were four fetal and two neonatal deaths. Procedure‐related fetal loss rate was 1.2% (95% confidence interval 0.04–2.4) per procedure and 3.8% (95% confidence interval 0.1–7.5) per pregnancy. Of the four procedure‐related losses, three were due to technically difficult intrauterine transfusions causing infection and preterm birth. Of the live born infants, 19% (95% confidence interval 11.3–26.7) were born before 32 weeks' gestation. The incidence of severe neonatal morbidity (respiratory distress syndrome, severe cerebral injury, sepsis) was 22.2% (95% confidence interval 13.4–30.2). Poor outcome (death, severe neonatal morbidity) was negatively associated with gestational age at first transfusion (<italic>p </italic>=<italic> </italic>0.001) and at birth (<italic>p </italic>=<italic> </italic>0.00006). Follow‐up of the infants was too incomplete to assess the neurodevelopmental outcome.</p> </sec> <sec id="aogs12590-sec-0008" sec-type="section"> <title>Conclusions</title> <p>Although overall survival is comparable with previous studies, our concern is procedure‐related infections and preterm births.
