title: Does intensive phototherapy produce hemolysis in newborns of 35 or more weeks gestation?
abstract: OBJECTIVE
  Because there is some in vivo and in vitro evidence that standard phototherapy might produce hemolysis, we wished to know whether intensive phototherapy produces hemolysis.
  
  
  METHODS
  We measured end-tidal carbon monoxide (CO) concentration corrected for ambient CO (ETCOc) in 27 newborn infants > or =35 weeks gestation receiving intensive phototherapy (average irradiance 43 microW/cm2/nm).
  
  
  RESULTS
  There was a steady decrease in the mean ETCOc over the course of the phototherapy.
  
  
  CONCLUSIONS
  Intensive phototherapy did not produce hemolysis in infants > or =35 weeks gestation.
