Many newborn babies have too high jaundice, and doctors will ask the incubator to turn on blue light. What is the principle of removing jaundice according to blue light?

Jaundice is a necessary disease process for every newborn, which usually appears for about a week. Blue light irradiation is an effective method to treat neonatal jaundice. What is the principle of blue light irradiation for neonatal jaundice? Let Bian Xiao go with you to find the answer!

Blue light irradiation is a simple, effective and rapid method to treat neonatal jaundice. Jaundice refers to the high bilirubin content in the baby's body, and bilirubin can absorb light. Under the action of light and oxygen, fat-soluble bilirubin is oxidized into water-soluble products, which can be excreted from bile or urine, thus reducing the concentration of serum unconjugated bilirubin. The absorption band of bilirubin is between 400 and 500 nm, especially the wavelength is between 420 and 440 nm, and the wavelength of blue light is just between 425 and 475 nm. The principle of blue light therapy is to convert bilirubin in the body into other substances through illumination, so that bilirubin accumulated in the body can find another outlet and jaundice symptoms can be improved.

Parents should also pay attention that blue light can decompose riboflavin in the body, that is, vitamin B2, so when the light exceeds 24 hours, it is necessary to supplement vitamin B2 to newborns to prevent vitamin B2 deficiency. Because children receive blue light irradiation treatment, water in the body is easily lost. Therefore, before treatment, they should be fed milk and some water, which can not only avoid electrolyte disorder, but also prevent children from sweating a lot after radiation treatment, causing dehydration, fever, acidosis and so on.

In the treatment of neonatal jaundice, if you want to know the situation of neonatal jaundice at any time, you need to use a jaundice measuring instrument. There is no need to draw blood to measure neonatal jaundice now. Simply press the probe gently on the baby's forehead, and the bilirubin concentration in the baby's skin tissue can be directly measured instantly. No need to draw blood, convenient for children, painless.

The above is Bian Xiao's answer to the principle of blue light irradiation for neonatal jaundice. I hope my answer is helpful to you!
