OBJECTIVE: To study the effect of a restrictive guideline for exchange transfusion (ET) on the number of top-up transfusions in neonates with Rh hemolytic disease. STUDY DESIGN: Retrospective study of all (near)-term neonates with Rh hemolytic disease admitted to our center between 2000 and 2008. In December 2005, policy changed from using liberal ET criteria to more restrictive ET criteria. We recorded the number of ETs and the number of top-up transfusions in the group of neonates before (group I, n = 156) and after (group II, n = 27) the guideline change. RESULTS: The percentage of neonates requiring an ET decreased from 66% (103/156) in group I to 26% (7/27) in group II (P < 0.01). The percentage of neonates receiving a top-up transfusion increased from 68% (105/154) in group I to 81% (22/27) in group II (P = 0.25). The median number of top-up transfusions increased from 1 (interquartile range 0-2) in group I to 2 (interquartile range 1-3) in group II (P = 0.01). CONCLUSION: In this study, restrictive ET criteria in neonates with Rh hemolytic disease lead to a reduction of the rate of ET but an increase in the number of top-up transfusions for neonatal anemia.
