ABSTRACT BL is considered more efficient than WL in bilirubin PD because of the greater energy output at the λ of maximal absorption for bilirubin. However, bilirubin PD using BL and WL with
similar irradiance (I) has not been studied. Since PD is dose related to I in vivo, it was hypothesized that BL and WL with similar I should have the same effect on bilirubin PD. Olympic
bili-lites were used with 8-20W duro-test vita-lite for WL and 8-20W F20T12/BB for BL. Sealed heparinized microhematocrit tubes with pre-exchange plasma samples were placed under light with
I varying from 0.9-10.2 μw/cm2/nm for 4 hrs. I was measured in the range of 425-475 nm using the Olympic bilimeter. The pH, albumin, and temp. of the samples under both light sources were
similar. The % PD of bilirubin is shown below. The mean I in comparison groups was the same. This study indicates that WL with similar I as BL is more effective at lower I in bilirubin PD.
These findings suggest that wavelengths other than those found in BL also contribute to bilirubin PD. ARTICLE PDF AUTHOR INFORMATION AUTHORS AND AFFILIATIONS * Cook County Hosp., Univ. of
