How high is jaundice to invade the brain?

There is a very common condition in newborn babies, and that is jaundice. Regarding jaundice, many parents who have had children should know that jaundice is basically a disease that occurs in every baby, but because of the different constitutions of babies, the time of jaundice is also different. Basically, jaundice has no effect on the baby's body, but some parents will worry that their baby's jaundice value is higher than average and affects the baby's brain, so will it?

How much jaundice is worth can hurt the brain

The effect on the brain cannot be judged by the number of jaundice values alone, but if the jaundice value exceeds 20mg/dl, it must be taken seriously.The impact of jaundice value is to be judged together with the baby's birth time and jaundice index, if the baby is born within 24 hours of jaundice, waist timely diagnosis and treatment. Generally, the jaundice value of newborns reaches its peak at 4-6 days of birth, and if the baby's jaundice has not subsided after a week, it is also considered to be pathological jaundice, which may cause brain damage.

How to determine the type of neonatal jaundice by index

1. Physiological jaundice appears two to three days after birth and peaks in four to six days. In this condition, the normal value of neonatal jaundice is between 2 mg/dl and 12 mg/dl.

2. Above the highest value of neonatal jaundice index, that is, when it exceeds 12mg/dl, or when the neonatal jaundice index rises too fast, rising more than 5mh/dl per day, the newborn may have rational jaundice.

Causes of high neonatal jaundice index

1. Newborns have too many red blood cells in the body, and too much bilirubin is produced after the red blood cells are destroyed, and bilirubin is the direct cause of jaundice, so newborns will have high jaundice.

2. The metabolism of bilirubin requires the participation of liver enzymes in the liver, and the liver function of newborns is not very perfect, so it leads to insufficient secretion of liver enzymes, which makes bilirubin excreted untimely, resulting in high jaundice.

3. The discharge of bilirubin requires the participation of the biliary tract, and the biliary function of newborns is not perfect, so the accumulation of bilirubin in the body cannot be discharged in time, resulting in high bilirubin and high jaundice.

4. Bilirubin can also be excreted from the stool, but the neonatal meconium is relatively viscous, resulting in the discharge of bilirubin is not very smooth, which makes the bilirubin in the newborn too high, resulting in high jaundice.

5. In addition, the incompatibility of mother and child blood group will also lead to the accumulation of bilirubin in the body of the newborn and cannot be discharged, and the pathological jaundice may be caused by neonatal diseases, such as neonatal asphyxia, premature birth, infection and other factors, which can lead to high neonatal jaundice.

6. Breastfeeding can also lead to the accumulation of bilirubin in the newborn's body, resulting in high jaundice in the newborn.

4. How to treat high jaundice index in newborns

1. Illumination:

When light is applied to the skin, the bilirubin flowing through the skin microvessels can cause a chemical reaction, thereby reducing the content of bilirubin in the blood and making jaundice recede. For general jaundice, only light is required.The advantage of illumination is that it is safe, inexpensive, and every hospital or doctor will do it; The disadvantage is that jaundice decreases slowly, and if the jaundice index rushes too high, it will not be relieved.

2. Exchange transfusion:

A more straightforward way is to replace all the blood containing high bilirubin in the newborn's body and transfuse fresh blood with normal bilirubin. If the jaundice index rises too quickly or too high, and there is a concern that brain cells will be damaged, it is necessary to use exchange transfusion to make jaundice come down in a short period of time. However, this method of exchange transfusion is not completely without side effects, and if the replacement blood is not suitable, jaundice will still persist; If blood is drawn too quickly, it can cause shock in the newborn; If aseptic measures are not done adequately during exchange transfusion, bacteria may invade the bloodstream and form neonatal sepsis.
