How much can blue light reduce jaundice in one day

If your baby has pathological jaundice, you must receive timely and effective treatment, because the symptoms of jaundice are quite harmful to the child. There are many treatment methods, and light therapy is relatively common. It mainly refers to irradiation under ultraviolet light. It has a good therapeutic effect and can gradually reduce the child's jaundice level. It can promote the body's excess hemoglobin to be excreted through urine. Let's learn about this aspect below.

Place the newborn naked under ultraviolet light. You can choose to have light irradiated on one side or on both sides at the same time. During treatment, the eyes need to be shielded to avoid damage to the retina, and the genitals and anus need to be covered with diapers. Under the action of ultraviolet rays, excess bilirubin in the body will be converted into certain water-soluble substances and excreted in urine. This method can reduce the bilirubin level in newborns to 7 mg/L. Alternatively, the same effect can be achieved by wrapping the newborn in a blanket-shaped jaundice treatment device for light therapy.

Differentiation between physiological jaundice and pathological jaundice

Parents should learn to distinguish between physiological jaundice and pathological jaundice. There are several differences between the two:

1. Time: It will appear 2-3 days after the birth of the newborn, and is most serious at 4-6 days. It will disappear on its own about one week to 10 days after it occurs (it may continue to the 3rd week in premature babies).

2. Jaundice color: usually lighter in color, mostly distributed on the face and body, and less common on the limbs, hands and feet.

3. Blood jaundice content: ≤12 mg/dL (full-term infants), ≤15 mg/dL (premature infants).

4. Other symptoms: The baby has good appetite and sleep, and gains weight. There are basically no other adverse symptoms.

1. Time: Jaundice occurs within 1 day (full-term infants) or 2 days (premature infants) after birth. The condition worsens rapidly and lasts for a long time (may last 2-3 weeks), and jaundice may even recur.

2. Jaundice color: It will become much darker in a very short time.

3. Blood jaundice content: serum bilirubin seriously exceeds the normal value, or the daily increase is ≥5 mg/dL.

4. Other symptoms: often accompanied by other symptoms. Some patients have seriously excessive serum conjugated bilirubin, which can reach 1.5 mg/L.
