Causes of high jaundice in babies

Newborns have too many red blood cells in their bodies, and after the red blood cells are destroyed, they produce too much bilirubin, which is the direct cause of jaundice, so newborns will have high jaundice.

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.

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

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

Maternal and child blood group incompatibility leads to the accumulation of bilirubin in the neonatal body and cannot be excreted, and pathological jaundice may be caused by neonatal diseases, such as neonatal asphyxia, premature birth, infection and other factors, bacteria can cause neonatal jaundice to be too high.

Breastfeeding can cause bilirubin to build up in newborns, causing high levels of jaundice in newborns.

Pediatric jaundice: The dangers of high neonatal jaundice

Physiological jaundice in newborns can resolve on its own, but pathological jaundice is a group of diseases composed of many causes that must be detected and treated as early as possible. Newborns with severe jaundice should be alert to the occurrence of kernicterus, especially immature infants, the younger the age of the month, the higher the incidence, generally within 12-48 hours after the occurrence of severe jaundice, lethargy, weakness in sucking, hypotonia, vomiting, lack of milk and other symptoms, at this time, if treated in time, can be fully recovered.

Pediatric jaundice: Physiological jaundice in newborns

In the past, it was believed that treatment was not necessary, and in view of the current promotion of eugenics and fertility and the improvement of the quality of the population, special attention should be paid to the following points:

Start breastfeeding early to speed up the passage of meconium.

Physiologic jaundice can be exacerbated by starvation, hypoxia, constipation, dehydration, acidosis, and brain hematoma and should be treated.

Hyperintercholisemia: the harm is mainly to produce kernicterus, the study of kernicterus, in the past, it was believed that indirect bilirubin is fat-soluble and lipophilic, which is a free state, and has an affinity with brain cells rich in cerebral phospholipids, and is easy to damage the nerve nucleus through the blood-brain barrier and cause kernicterus.

Pathological jaundice, regardless of the cause, can cause "kernicterus" in severe cases, and its prognosis is poor, in addition to causing nervous system damage, severe can cause death.Therefore, the prevention of pathological jaundice in newborns should be emphasized, such as preventing infection of toxoplasma gondii and rubella virus during pregnancy, especially in the first trimester; prevent the onset of sepsis after birth; Newborns are vaccinated against hepatitis B at birth, etc.
