Patient's question:
The child was born with jaundice symptoms on the third day. A bilirubin test showed 16.3, and blue light treatment was started. The next day, the bilirubin level was measured at 16.4. Should the treatment continue? How should it be treated?Follow-up question: (2008-3-11 1:55:05) The child is now the eighth day. Yesterday, liver function tests were conducted with the following results: Total bilirubin 308.3 umol/L, direct bilirubin 12.9 umol/L, indirect bilirubin 295.4 umol/L, alanine aminotransferase 3.0 IU/L, and gamma-glutamyl transferase 75.0 IU/L. The yellowness on the face has been gradually fading. Diet, bowel movements, and sleep are normal.
Doctor's answer:
Newborn jaundice is generally divided into two major categories: physiological jaundice and pathological jaundice. Physiological jaundice is a normal physiological phenomenon. Due to the metabolic characteristics of bilirubin in newborns, approximately 60% of full-term infants and over 80% of preterm infants may develop jaundice 3-5 days after birth, but they are generally in good condition. In full-term infants, jaundice usually resolves within 14 days, while in preterm infants, it may persist for up to 3-4 weeks. Pathological jaundice, on the other hand, is abnormal and is generally associated with the following factors: ① Bacterial infections and neonatal sepsis, as well as viral infections such as hepatitis A virus, hepatitis B virus, and cytomegalovirus; ② Neonatal hemolytic disease; ③ Congenital biliary atresia and biliary cysts; ④ Breast milk jaundice, which typically appears 4-7 days after birth, peaks within 2-3 weeks, and bilirubin levels decline within 1-3 days after stopping breastfeeding. If there is no significant decline after 3 days, breast milk jaundice can be ruled out; ⑤ Other factors such as genetic diseases and drug-induced jaundice. When a newborn exhibits any of the following conditions, pathological jaundice should be considered: jaundice appearing early (within 24 hours after birth); severe jaundice or rapid progression; prolonged duration of jaundice (more than 2 weeks in full-term infants, more than 4 weeks in preterm infants); or jaundice that reappears after resolution. Pathological jaundice caused by any reason should be treated by identifying the underlying cause. This is particularly crucial for premature infants within the first week and those with severe hypoxia, acidosis, intracranial lesions, or severe infections, as early and active treatment is necessary to prevent adverse outcomes.Diagnosis
1. A history of difficult delivery, maternal infection and medication use before delivery, blood transfusion history, or a family history of jaundice, among other causative factors.
2. Jaundice appearing within 24 hours after birth or not appearing until after 1 week, rapidly worsening or persisting for a long time, or reappearing after resolution, accompanied by symptoms such as poor appetite, vomiting, lethargy, irritability, hepatosplenomegaly, etc.
3. Laboratory tests: In full-term newborns, serum bilirubin > 205.2 μmol/L; in preterm infants, direct bilirubin > 256.5 μmol/L, with elevated levels of both conjugated and unconjugated bilirubin, indicating pathological jaundice. Physiological jaundice should resolve within 7-10 days after birth. If bilirubin levels remain above 34.2 μmol/L, it is considered pathological jaundice.
Differential Diagnosis
- Physiological Jaundice: Appears 2-3 days after birth, persists for about 1 week, primarily characterized by elevated unconjugated bilirubin, with no clinical symptoms.
- Neonatal Hemolytic Disease: Appears within 24 hours or the second day after birth, persists for one month or longer, primarily characterized by elevated unconjugated bilirubin, hemolytic anemia, hepatosplenomegaly, and incompatibility between mother and infant blood types. Severe cases may lead to bilirubin encephalopathy.
- Breast Milk Jaundice: Appears 4-7 days after birth, persists for about 2 months, primarily characterized by elevated unconjugated bilirubin, with no clinical symptoms.
- Neonatal Sepsis: Appears 3-4 days or later after birth, persists for 1-2 weeks or longer. Early stages show primarily elevated unconjugated bilirubin, while later stages show primarily elevated conjugated bilirubin, hemolytic in nature, and may progress to hepatocellular in the later stages, accompanied by signs of infection and toxicity.
- G-6-PD Deficiency: Appears 2-4 days after birth, persists for 12 weeks or longer, primarily characterized by elevated unconjugated bilirubin, hemolytic anemia, and often triggered by certain factors.
- Neonatal Hepatitis: Appears several days to weeks after birth, persists for 4 weeks or longer, primarily characterized by elevated conjugated bilirubin, obstructive and hepatocellular in nature. Jaundice and stool color change dynamically, with elevated GPT levels. Hormones may help resolve jaundice.
Treatment
1. Western Medicine Treatment
(1) Phototherapy: The newborn lies naked in a phototherapy box, with eyes and testicles covered by black paper. Single light (8 20W blue fluorescent tubes arranged in an arc, with a distance of 2.5 cm between tubes, at a distance of 35-50 cm from the infant) or double light (6 tubes above and below, with a distance of 25-35 cm from the infant) can be used. Treatment lasts for 24-48 hours, and it can be stopped once bilirubin levels drop below 120 μmol/L.
(2) Enzyme inducers: Phenobarbital (Rumina) is commonly used. Administered in the first week after birth at a dose of 4-8 mg/kg/day for 4 consecutive days, with effects appearing within 3-7 days. Alternatively, a high initial dose (8 mg/kg/day) can be given, followed by a maintenance dose (4 mg/kg/day). Adding nicotinamide (Koramine) at 100 mg/kg/day can enhance efficacy.

Prevention
1. Maintain good prenatal care, treat abnormalities promptly, and avoid fetal hypoxia, asphyxia, or infection in the womb.
2. Care for newborns carefully. Ensure proper warmth (room temperature should be maintained at 24-27°C), fresh and well-ventilated air (ventilate for 30 minutes in the morning and afternoon). Keep the newborn's body temperature between 36.5-37.5°C.
3. Practice good hygiene: Infants have delicate skin and poor resistance to infection. Bathe them frequently, keep them clean, and pay special attention to skin folds. Clean the umbilical fossa daily with alcohol swabs. Ensure that underwear and diapers are clean, soft, and regularly disinfected to prevent cross-infection. After each bowel movement, wipe with a warm, damp towel and apply diaper cream or tannic acid ointment.
4. If pathological jaundice is suspected, seek medical attention promptly.
