Heme Catabolism and Bilirubin Production in Readmitted Jaundiced Newborns.
The Journal of pediatrics
We measured end-tidal CO levels in 50 jaundiced newborns readmitted for phototherapy at age 54-244 hours. The median end-tidal CO level was 1.55 ppm, suggesting that hemolysis is not the primary contributor to the hyperbilirubinemia in many readmitted newborns.
