title: Treatment requirements of infants with rhesus isoimmunisation within a geographically defined area.
abstract: OBJECTIVE
  To provide population based data on the treatment requirements of infants with rhesus isoimmunisation.
  
  
  METHODS
  Twenty nine hospitals in South Thames in which 81 119 deliveries occurred between February 1999 and January 2000.
  
  
  METHODS
  Every month, a clinician identified in each of the hospitals sent back a postcard indicating whether or not an infant with RhD had required treatment in their institution. Antenatal and postnatal information was then requested from all those who gave positive responses.
  
  
  METHODS
  Requirement for postnatal treatment for rhesus isoimmunisation.
  
  
  RESULTS
  During the one year study period, only 26 infants required treatment for rhesus isoimmunisation. The median duration of phototherapy of the 26 infants was five days (range 1-12). Seven infants required at least one exchange transfusion (two required two exchange transfusions), and seven infants received one "top up" transfusion. None received erythropoietin and no infant died.
  
  
  CONCLUSIONS
  The results suggest that few infants require treatment for rhesus isoimmunisation.
