Introduction
Phototherapy is the simplest and most effective method for reducing serum unconjugated bilirubin levels. If a child has a relatively high degree of jaundice, treatment may require about 10 days; if the jaundice is mild, it may gradually resolve after 3 to 5 days of phototherapy. During treatment, once bilirubin levels have decreased to a safe range, blue light therapy can be discontinued.
The duration of blue light phototherapy for infant jaundice should be determined based on the severity of the condition.
Once elevated jaundice is detected in infants, prompt intervention is generally required to prevent complications such as kernicterus. Blue light phototherapy is the simplest and most effective method for reducing serum unconjugated bilirubin levels. In clinical practice, there is no strict time limit for blue light treatment. If the infant has severe jaundice, the treatment duration may need to be extended, typically up to around 10 days. For milder cases, 3 to 5 days of phototherapy may be sufficient for gradual recovery. During treatment, bilirubin levels should be monitored dynamically; once they fall within a safe range, phototherapy can be discontinued.
During blue light exposure, maximum skin surface area should be exposed to the light, while the eyes and genital area must be covered with opaque cloth to prevent potential adverse effects.
