ABSTRACT

Introduction: Different types of phototherapy for hyperbilirubinemia used; white and blue fluorescent tubes, halogen light, fiber optic, and light emitting by diode (LED), all meet the recommendations of the American Academy of Pediatrics (30 μW/cm²/nm irradiation and wavelength of 460 to 490 nm). Use innovated a light panel high brightness blue LED to use as phototherapy, which was able to be effective as existing phototherapy devices.
Material and methods: Phototherapy was used in three groups; phototherapy with blue fluorescent light (G-I), fiber optic (G-II) and the LED panel with blue light (G-III). 15 infants was included in each group with phototherapy criteria, was measured bilirubin levels at baseline, 24, 48 and 72 hours of treatment. We compare the results of bilirubin decline in each group.
Results: The G-I, G-II and G-III had an average 20.40 mg/dL, 13.69 mg/dL and 15.45 mg/dL (p = 0.004) at baseline. The average at 24 hours G-I 16.91 mg/dL, G-II 10.77 mg/dL and G-III 11.09 mg/dL (p = 0.003). After 48 hours, the average was G-I 13.43 mg/dL, G-II 8.69 mg/dL and G-III 9.62 mg/dL, (p = 0.004). At 72 hours the average was G-I 9.75 mg/dL, G-II 7.45 mg/dL and G-III of 9.93 mg/dL (p = 0.42).
Discussion: The three types of phototherapy were able to decrease the levels of bilirubin. The LED panel was better than the fluorescent blue light and equal than the fiber optic. With the above managed to get a blue LED phototherapy lamp effective in reducing bilirubin levels at low cost.
