Pediatric outcome in Rhesus hemolytic disease treated with and without intrauterine transfusion.

Objective: To study the short-term morbidity in Rhesus hemolytic disease of infants treated either with or without intrauterine transfusions (IUT).

Study Design: All term and near term infants (gestational age > or = 36 weeks) with neonatal Rhesus hemolytic disease admitted to our center between January 2000-March 2005 were retrospectively included in the study. We recorded the duration of phototherapy, the need of exchange transfusions, and the need of top-up red blood cell transfusions until 6 months of age.

Results: A total of 89 infants were included, of whom 52 received at least one IUT. Duration of phototherapy in the IUT and no-IUT group was 3.8 and 5.1 days, respectively (P = .01). The percentage of infants requiring an exchange transfusion in the IUT group was 71% compared to 65% in the no-IUT group (P = .64). The percentage of infants requiring a top-up transfusion in the IUT and no-IUT group was 77% and 26.5%, respectively (P < .01).

Conclusion: Infants with Rhesus hemolytic disease treated with IUT required less days of phototherapy and more top-up red blood cell transfusions than neonates without IUT. However, the need for exchange transfusion was similar in both groups.
