Jaundice occurs in the first few days of life

"Neonatal jaundice" refers to a condition in which bilirubin accumulates in the body during the neonatal period, resulting in an increase in the level of bilirubin in the blood, which is characterized by yellow staining of the skin, mucous membranes, and sclera of the eyeball. The following is an article about jaundice in the days after the baby is born, welcome to read!

The baby has jaundice for a few days after birth

At 12 weeks' gestational age, bilirubin is already present in the amniotic fluid. At this time, the fetus relies on the placenta to supply blood and oxygen, and the unconjugated bilirubin produced by the destruction of fetal red blood cells is mainly removed through the placenta to the maternal circulation, so the newborn is born without jaundice.

After birth, the newborn begins to breathe oxygen with its own lungs and must dispose of the metabolite of hemoglobin - unconjugated bilirubin on its own. However, at this time, the liver function of the newborn is imperfect, the enzyme system is not mature, and the excessive bilirubin cannot be excreted from the body after treatment, and can only accumulate in the blood. This bilirubin is like a yellow dye, and with the flow of blood, the skin and sclera of newborns are dyed yellow, and "neonatal jaundice" appears.

According to statistics, 50% of newborns are full-term babies, 80% ofprematureJaundice can occur, so "neonatal jaundice" is a common phenomenon. Most of the "neonatal jaundice" is physiological jaundice, which can resolve spontaneously and does not require special treatment, but if it is pathological jaundice, it should be paid enough attention. So, what are the characteristics of pathological jaundice?

Premature: For example, jaundice on the first day of a new student is definitely not normal.

Severe: Severe jaundice is certainly not normal. If bilirubin is greater than 12 mg/dl in term infants,prematureMore than 15 mg/dl, this is abnormal, and the clinical diagnosis is called "neonatal hyperbilirubinemia".

Jaundice progresses too quickly: it rises by more than 5mg/dl per day, which is abnormal.

Delayed regression: normal jaundice, which usually resolves after two weeks in full-term infants and one month in premature babies. If the jaundice does not go away, the possibility of abnormality should be considered.

Regression and recurrence: Even if the jaundice has receded, and the result is yellow again, this part of the children must also be abnormal.

Increased direct bilirubin: Normally, direct bilirubin accounts for a small proportion of bilirubin, and if it is high, the child will be black and yellow, which is abnormal. There are also children with biliary tract problems, and the direct bilirubin will be elevated.

Hazards of pathological jaundice: mainly it can cause damage to the brain of newborns. This is because the newborn's brain is immature and the "blood-brain barrier" is not perfect, and jaundice can enter the brain through blood circulation, and once it enters the brain, the damage caused is often irreversible. The newborn's "blood-brain barrier" is usually fully developed between 10 and 15 days after birth, at which time bilirubin is less likely to enter the brain and is less likely to cause damage to the child's brain. That's why we're focusing on jaundice, with a focus on newborns within two weeks of age.

Pediatric jaundice prevention "neonatal jaundice"

First of all, let the child suck more, eat more milk, ensure the intake, stimulate the child to defecate and urinate more, so that bilirubin can be excreted from the body, which can effectively reduce the rise rate of jaundice; Especially in the first three days of the child's birth, the black stool discharged is meconium, and there is a lot of bilirubin in the meconium, so let the child eat more in the first three days to stimulate bowel movements, and try to expel the meconium within three days, and the jaundice will not be too heavy.There is also an auxiliary method, which is to bask in the sun, because the sun's rays also have a certain effect on reducing jaundice.

However, how to judge and prevent "neonatal jaundice", it is best to go to the hospital and let the doctor assess the degree of jaundice of the child and propose a prevention and treatment plan, especially for children within 14 days after birth, so as not to delay the child's treatment and cause lifelong brain damage to the child.
