Neonatal jaundice is the most common phenomenon in the neonatal period, especially in early neonates, which refers to newborns within the first week of life. About 80% of full-term infants can visually exhibit signs of jaundice. Jaundice can be categorized into physiological jaundice and pathological jaundice. Typically, physiological jaundice appears about two to three days after birth. If it is pathological jaundice, it may appear earlier, possibly within the first twenty-four hours after birth. Generally, if the jaundice appears early, progresses quickly, and is severe, it is necessary to intervene and treat promptly.

When does neonatal jaundice go away?

Neonatal jaundice is a common phenomenon in the newborn period, with 80% of full-term infants visibly exhibiting jaundice. Jaundice is divided into physiological jaundice and pathological jaundice. In full-term infants, physiological jaundice generally lasts about two weeks and ordinarily subsides within that time. For preterm infants, it typically does not last more than four weeks. However, if the jaundice progresses quickly, appears early, and is severe, reaching pathological levels, intervention and treatment are necessary. The duration of jaundice can vary depending on the baby’s condition. Without intervention, the duration of jaundice may be prolonged. Therefore, it is advisable to regularly monitor jaundice and actively intervene with treatment if abnormalities are present.

How to deal with neonatal jaundice hemolysis?

Neonatal hemolytic disease refers to alloimmune hemolysis caused by maternal-fetal blood type incompatibility, commonly seen in life with A, B, O blood type mismatches, and Rh blood type mismatch is less common. Once neonatal hemolytic disease is diagnosed, aggressive treatment must be pursued. Initially, phototherapy treatment is recommended, commonly referred to as blue light therapy. Additionally, medication therapy for the child is necessary, frequently involving albumin and intravenous immunoglobulin, along with the use of sodium bicarbonate to correct acidosis. If the aforementioned treatments do not yield satisfactory results, blood exchange treatment should be considered for the child. This mainly involves removing free antibodies and sensitized red blood cells from the blood, thereby alleviating hemolysis and ultimately achieving therapeutic goals. (Please use medication under the guidance of a doctor.)

Does neonatal jaundice require medication?

Neonatal jaundice is divided into physiological jaundice and pathological jaundice. Physiological jaundice appears two to three days after birth, peaks around the fifth or sixth day, and then gradually subsides, so there is no need for medication in this case. If it is neonatal pathological jaundice, merely taking medication does not solve the problem; this requires treatment with blue light therapy. At the same time, it is important to identify the cause of the jaundice and treat it accordingly. In such cases, medication is actually not necessary. Therefore, it is crucial to first determine whether neonatal jaundice is physiological or pathological. Physiological jaundice requires no intervention, while pathological jaundice necessitates hospital treatment. Regarding the increasingly common breastfeeding jaundice, medication is generally not needed; monitoring of the jaundice in the child is essential, however. If the jaundice level continues to rise and exceeds 15 mg/dl, blue light therapy is also required. If the condition is not severe, exposing the child to more sunlight and waiting for the jaundice to subside naturally is sufficient.

When does neonatal jaundice completely disappear?

Neonatal jaundice is one of the most common conditions in newborns. Due to the metabolic characteristics of bilirubin in newborns, about 50%-60% of full-term infants and 80% of preterm infants experience jaundice. Jaundice is categorized into physiological jaundice and pathological jaundice. If it is physiological jaundice, the duration typically does not exceed two weeks in full-term infants, and in preterm infants, it can extend up to three to four weeks, generally not exceeding four weeks. If the jaundice progresses quickly and is severe, and if its resolution is delayed, there might be an underlying pathological jaundice. Pathological jaundice may involve certain pathological factors, necessitating a hospital visit. Based on the baby’s specific conditions, targeted examinations should be conducted, and treatment should focus on the underlying cause to actively manage the jaundice. The length of time jaundice takes to resolve may vary depending on the cause or the condition of the baby. How the jaundice subsides depends on the condition. If pathological jaundice is not promptly managed, the severity of the jaundice may increase, and there may be a risk of severe complications. Therefore, if the jaundice level is high and parents are unsure, it is advised to have it checked at a hospital. If pathological jaundice is confirmed, timely intervention and treatment are necessary.

What does a newborn jaundice blood test check for?

Neonatal jaundice is one of the common symptoms during the neonatal period. It may indicate both normal developmental processes and certain diseases. If it is normal physiological jaundice, there is no need for blood tests. However, if pathological jaundice is suspected, blood tests are generally required. The most common test is a liver function test to determine the level of bilirubin in the blood. Additional tests might be conducted, especially if there is an incompatibility in the blood type between the mother and child. In such cases, tests for the baby's blood type and hemolysis are necessary, along with tests for common infection markers. If the mother had other abnormalities before pregnancy, further blood tests might be warranted based on potential conditions that the baby might exhibit.
