What therapeutic intervention is commonly used in the management of mild jaundice in infants?

Phototherapy is the standard therapeutic intervention used in the management of mild jaundice in infants, particularly those diagnosed with physiological jaundice or mild hyperbilirubinemia. This treatment involves exposing the infant to specific wavelengths of light, which helps to convert bilirubin into a water-soluble form that can be excreted more easily through urine and stool.

The effectiveness of phototherapy lies in its ability to break down bilirubin, reducing its levels in the bloodstream and thus alleviating the yellowing of the skin and eyes associated with jaundice. It is a non-invasive and widely accepted method for managing this common condition among newborns, particularly because bilirubin can be toxic at elevated levels.

Other interventions such as exchange transfusion, while effective in severe cases of jaundice, are not indicated for mild jaundice due to the potential risks associated with more invasive procedures. Intravenous immunoglobulin is primarily used in cases of hemolytic disease of the newborn rather than mild jaundice, and medicated creams are not a recognized treatment for jaundice in infants. Therefore, phototherapy remains the most appropriate and commonly used intervention for managing mild jaundice in this patient population.
