    Study Notes

    Visual Inspection and Bilirubin Level

    • Visual inspection is not a reliable measure of bilirubin level, as it can be influenced by skin tone and other factors.

    Jaundice in Newborns

    • Jaundice before age 24 hours is considered a medical emergency due to the potential for severe underlying conditions.

    Predicting Phototherapy and Follow-up

    • The bilirubin level predicts the need for phototherapy and guides the timing of follow-up after discharge.

    Peak bilirubin Levels in Newborns

    • A peak bilirubin level occurs in 6.1% of well-term newborns at a total bilirubin (TB) level of 18 mg/dL.

    Factors Affecting Bilirubin Levels

    • Changes in total bilirubin (TB) levels in newborns are influenced by factors such as hemolysis, inadequate milk intake, and livermaturity.
