phototherapy
Light therapy treatment for neonatal jaundice using specific wavelengths to break down excess bilirubin.
Full Definition
Phototherapy is the primary treatment for neonatal hyperbilirubinemia, utilizing blue light (wavelength 420-470 nm) to convert unconjugated bilirubin into water-soluble photoisomers that can be eliminated without liver conjugation. Treatment delivery methods include conventional phototherapy units, LED systems, and fiber-optic blankets. Effective phototherapy requires maximum skin exposure, appropriate light intensity, and continuous monitoring for side effects including temperature instability, increased fluid losses, and potential retinal damage. Treatment duration depends on bilirubin levels, infant risk factors, and response to therapy. Proper eye protection and temperature monitoring are essential safety considerations during treatment.
Usage
Usage note: Distinguish from other forms of light therapy; specify type (conventional, LED, fiber-optic) when relevant.
