Can newborn jaundice rebound after blue light therapy, and can it be treated again?

Patient's question:

My baby was admitted to the hospital for blue light treatment due to high jaundice when he was three days old. After three days, his condition stabilized, and he was discharged. However, I noticed that he turned yellow again the next day. Is it a rebound? Can he still receive blue light treatment?

Doctor's answer:

In China, the most commonly used method for treating jaundice is blue light therapy. Newborns lie in a phototherapy box. Their eyes are protected with black eye patches to prevent retinal damage. The perineum and anus are covered with diapers, while the rest of the body is exposed. Continuous or intermittent irradiation for 2 to 48 hours (usually not exceeding 4 days), either unilateral or bilateral, until the bilirubin level drops below 7 mg/ml, the treatment can be stopped. If jaundice recurs, the treatment can be continued.
