The yellow coloring of the skin and sclera of the eyes caused by an increase in bilirubin in the body is called “jaundice. Bilirubin is a product of aging and death of red blood cells in the body. If too much bilirubin exceeds the processing capacity of the liver, the processing capacity of the liver cells for bilirubin decreases, and bilirubin cannot be excreted from the body, jaundice is caused. Neonatal jaundice is a disease characterized by yellowing of the skin, eyes and urine around the baby after birth, and is called fetal yellow in Chinese medicine. Neonatal hemolysis is the most common jaundice disorder, which is caused by hemolysis of fetal red blood cells due to the incompatibility between the blood type of the newborn and the mother, resulting in anemia, edema, hepatosplenomegaly, and hyperbilirubinemia. If a large amount of bilirubin in the body infiltrates the nucleus of the central nerve cells, the jaundice that occurs is more serious and is medically called nuclear jaundice, which has a higher mortality rate and is prone to sequelae. For physiological jaundice, mothers do not need to worry too much, because babies with physiological jaundice can recover on their own in about a week after the onset of jaundice. However, if your baby develops pathological jaundice, you must be highly alert and seek medical attention in a timely manner. If the condition continues to worsen, it may lead to convulsions, respiratory failure, nuclear jaundice and other conditions. Respiratory failure and nuclear jaundice can seriously endanger the baby’s life, and even if the baby survives after resuscitation, the baby is not in good condition because neurological damage has been caused, leaving sequelae such as cerebral palsy, hearing damage, and abnormal brainstem auditory evoked potentials.
