Several common neonatal pathological jaundices

Pathologic jaundice, breast milk

This is a special type of pathological jaundice, which is characterized by the continuous deepening of bilirubin after the peak of physiological jaundice, and the bilirubin reaches 10~30mg/dl. If breastfeeding is stopped in time, jaundice will weaken in about 2~4 days and disappear within 6~10 days.

Pathological jaundice is infectious

It is mostly intrauterine infection, which is mainly caused by impaired liver cell function due to viral infection or bacterial infection.Viral infections are most common with cytomegalovirus and hepatitis B virus, and bacterial infections are most common with sepsis. It is characterized by jaundice that persists or resolves and then persists.

Pathologic jaundice obstructive

Obstructive jaundice is mostly caused by congenital biliary malformations, with congenital biliary atresia being the most common, which is characterized by the appearance of 1~2 weeks or 3~4 weeks after birth, and the degree gradually deepens, and the color of the stool gradually changes from normal color to light yellow, or even white clay color.

Pathological jaundice hemolytic

The most common cause of hemolytic jaundice is ABO hemolysis, but not all newborns with ABO incompatibility develop hemolysis. It is characterised by jaundice that develops within the first 24 hours of birth and progressively worsens.

The difference between physiological and pathological conditions of jaundice in children

Physiological jaundice

On the face and upper body, the baby is in good physical condition, has a normal body temperature, normal appetite, normal bowel and bowel movements, and normal growth and development.

It usually appears 2~3 days after birth, and gradually worsens, reaches a peak on the 4th ~ 6th day, and the jaundice gradually decreases in the second week, and the serum bilirubin is more than the normal 2mg/dl, but less than 12mg/dl.

In full-term newborns, jaundice usually resolves after 2 weeks of birth.prematureIt usually resolves 3 weeks after birth.

Pathologic jaundice

Jaundice caused by the disease, because its external manifestations are similar to physiological jaundice, often make it difficult for new parents to distinguish:

Jaundice appears too early: within 24 hours of birth in full-term babies,prematureWithin 48 hours.

The degree of jaundice is severe: it often affects the whole body, and the skin and mucous membranes are obviously yellow. When serum bilirubin is checked, bilirubin exceeds 12 mg/dl, rises more than 5 mg/dl per day, or is accompanied by other clinical symptoms.

Late resolution of jaundice: It lasts too long beyond the resolution time of physiologic jaundice, or it has already resolved and reappears, or it has regressed at its peak.

When the baby is found to have jaundice, parents should pay attention to observation, distinguish the difference between physiological jaundice and pathological jaundice, and send it to the hospital in time to avoid delaying the condition.
