The effectiveness of a new device for phototherapy in the treatment of nonhemolytic hyperbilirubinemia (Wallaby Phototherapy System) was evaluated. 46 healthy term infants, appropriate for gestational age and with serum bilirubin > 12 mg/dl in the first 3 days of life or > 15 mg/dl after 3rd day were randomly assigned to a treatment group (24 hours of light exposure with Wallaby Phototherapy System) and to a control group (any treatment for hyperbilirubinemia). Body temperature, weight, feeding and hydration were recorded during the study period. Serum bilirubin and haematocrit were done every 12 hours in all babies. In the treated group we found a decrease of 5.1% and of 7.8% at 12 and 24 hours, while an increase of 3.37% and of 2.9% at 12 and 24 hours was found in the control group. After 24 hours the serum bilirubin level was significantly lower in the treated group than in the control group (p < 0.05). No newborn of the treated group needed conventional phototherapy versus 4 control infants (17.4%). The conclusion of our study is that the Wallaby System is useful in the treatment of neonatal nonhemolytic hyperbilirubinemia even if its effectiveness for higher bilirubin levels has still to be tested.
