JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 476 OP 478 DO 10.1136/adc.51.6.476 VO 51 IS 6 A1 F Ebbsen A1 J Moller YR 1976 UL http://adc.bmj.com/content/51/6/476.abstract AB In newborn infants with rhesus haemolytic disease the effect of phototherapy with blue light (28 cases) on both sides of the infant was compared with the effect of traditional white light phototherapy on one side of the infant (42 cases). The number of exchange transfusions performed after the first 12 hours of life was significantly lower in the blue double light group. It is concluded that the application of blue double light may be a superior means of applying phototherapy in rhesus haemolytic disease.
