Patient's question:
Baby was found to have jaundice on the second day of birth, and blood tests showed a level of 340. After three days of hospital treatment, the jaundice level decreased. However, in the past two days, the jaundice index has been fluctuating. It dropped to 220 the day before yesterday, then rose to 250 yesterday morning. After treatment, it decreased to 202 yesterday, but today morning it rose to over 260. Is it normal for the baby's condition to fluctuate like this? How low does the jaundice index need to be to be considered cured? How many more days should be observed after treatment before discharge? Will it still fluctuate after discharge?Doctor's answer:
How to Identify Neonatal Jaundice? Carefully observing the changes in the baby's jaundice is very important for distinguishing between physiological jaundice and pathological jaundice for treatment. Parents can identify it based on the following characteristics:Physiological jaundice in newborns is generally not severe, with the following features:
① Jaundice usually appears 2-3 days after birth.
② Jaundice gradually deepens, reaching its peak between days 4-6, then gradually subsides.
③ Full-term newborns typically show jaundice that disappears within 2 weeks after birth, while premature infants usually take about 3 weeks.
④ The degree of jaundice is usually mild, with the skin appearing pale yellow. Jaundice often affects only the face and upper body. The baby is generally well, with normal temperature, appetite, bowel and urine color, and normal growth and development.
⑤ Serum bilirubin levels exceed normal by 2 mg/dL but are less than 12 mg/dL. If the baby's jaundice falls into this category, parents need not worry.
Pathological jaundice has the following characteristics:
① Jaundice appears too early, within 24 hours after birth.
② Jaundice persists for too long, lasting beyond the normal duration, or returns after initially subsiding, or worsens progressively after reaching its peak.
③ The degree of jaundice is severe, often affecting the entire body, with yellowing of the skin and mucous membranes.
④ Serum bilirubin levels exceed 12 mg/dL or rise too quickly, with an increase of more than 5 mg/dL per day.
⑤ In addition to jaundice, other abnormal conditions are present, such as fatigue, reduced crying or movement, decreased appetite, or unstable body temperature.
Severe pathological jaundice can lead to bilirubin encephalopathy, commonly known as "kernicterus," which causes neurological damage, resulting in severe long-term consequences like intellectual disability or even death. Therefore, if any of the above five conditions are present when a baby develops jaundice, parents should pay close attention to ensure early detection of pathological jaundice for timely treatment.
Caring for a Jaundiced Baby
When a newborn shows signs of jaundice, parents should:
(1) Assess the severity of jaundice. Under natural light, observe the extent of yellowing on the baby's skin. Mild jaundice is characterized by yellowing only on the face; moderate jaundice involves the torso; severe jaundice affects the limbs and palms/soles.
(2) Monitor stool color. If the stool appears clay-colored, pathological jaundice should be considered, often caused by congenital biliary malformations. If jaundice is severe, accompanied by symptoms, or stool color is abnormal, seek medical attention promptly to avoid delayed treatment.
(3) Ensure the meconium is passed as soon as possible. Meconium contains a high amount of bilirubin, and if it is not fully eliminated, bilirubin can be reabsorbed into the bloodstream through the newborn's unique hepatointestinal circulation, worsening jaundice.
(4) Provide the newborn with adequate fluids, as insufficient urination hinders bilirubin excretion.
Medical Advice:
Most newborns may develop skin yellowing within the first week of life, a condition known as neonatal jaundice in medical terms. This occurs due to bilirubin deposition on the skin surface. Newborns produce excess bilirubin because their red blood cells are too numerous and have a short lifespan, making them prone to destruction. Additionally, immature liver function in newborns limits bilirubin metabolism, contributing to jaundice.
Neonatal jaundice can be either physiological or pathological. Physiological jaundice resolves on its own without special treatment. Pathological jaundice, caused by disease, disrupts bilirubin metabolism and occurs during a specific period in newborns, often worsening physiological jaundice and making it difficult to distinguish. Pathological jaundice is classified into infectious and non-infectious types. Infectious jaundice is caused by bacterial or other pathogen infections, such as viruses, syphilis, or toxoplasmosis. Non-infectious jaundice includes hemolytic jaundice, biliary atresia, and genetic diseases.
In addition to physiological and pathological jaundice, there is also a type called breast milk jaundice. Its characteristics include:
- Jaundice levels higher than physiological jaundice.
- Prolonged duration, sometimes lasting up to three months.
- Generally, the baby remains well with no other identifiable causes of jaundice.
- After stopping breastfeeding for three days, jaundice levels drop significantly.
Breast milk jaundice is related to the reabsorption of bilirubin in the intestines. It usually does not lead to bilirubin encephalopathy. However, it is important to note:
To diagnose breast milk jaundice, pathological jaundice must first be ruled out.
