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.

What to do with neonatal jaundice?

Neonatal jaundice is the most common disease in newborns, mainly characterized by yellowing of the skin. Generally, normal babies also exhibit jaundice, but this is a type of physiological jaundice. If the baby's jaundice appears early, such as within twenty-four hours, or if the jaundice progresses rapidly with significantly rising jaundice levels, or if it is particularly severe, or if the jaundice lasts for a long duration, or if the jaundice recurs after fading, these are considered pathological jaundice. It is generally advised for pathological jaundice to consult a neonatal specialist for a detailed examination of the baby to determine whether treatment intervention is necessary. If the jaundice is severe and parents are worried, it is recommended to go to the hospital in a timely manner, as hospitalization for treatment may be needed. If the jaundice level is too high and there are some pathological factors, and parents are unable to observe the baby well and the baby's condition is not good, and the jaundice continues to rise, it could potentially progress to the brain, leading to bilirubin encephalopathy, which is a serious complication. Therefore, high jaundice levels still require timely intervention. If the jaundice is at its peak, it is recommended to test for jaundice daily, as timely intervention when jaundice levels are high can prevent serious complications.

How to test for neonatal jaundice?

Neonatal jaundice is relatively common during the newborn period, with about 80% of full-term babies showing visible yellowing of the skin. Typically, jaundice is measured using a jaundice meter, such devices are available in common community hospitals as well as in major hospitals like People's Hospital or maternity and children's health facilities, or other comprehensive hospitals. This is generally done through transcutaneous bilirubin measurement. If the transcutaneous bilirubin levels are high, it is necessary to determine the specific degree of jaundice, at which point a blood test to check liver function is required to assess the bilirubin levels more precisely.

Newborn jaundice can be divided into several types.

Neonatal jaundice is one of the common symptoms during the neonatal period, especially in early newborns. It can be a symptom of the normal developmental process of newborns, or it can be a manifestation of certain diseases. Neonatal jaundice is relatively common in newborns, with about 80% of full-term infants visibly showing jaundice. Jaundice is classified into physiological jaundice and pathological jaundice. If it is pathological jaundice, there are different classifications. Based on different characteristics of bilirubin elevation, it is divided into high direct bilirubinemia and high indirect bilirubinemia. Physiological jaundice does not require intervention. However, if it is pathological jaundice, it is necessary to clarify its classification and determine which type it belongs to. Generally, if it is pathological jaundice, timely intervention and treatment are needed. If untreated, and if the jaundice level significantly increases, it may lead to serious complications.

Will newborn jaundice cause the ears to turn yellow?

Neonatal jaundice is one of the common symptoms in neonates, especially in early newborns. It can be a symptom of normal development in newborns, or it can be a manifestation of certain diseases. Jaundice is generally divided into physiological jaundice and pathological jaundice, with the main symptom being the yellowing of the skin and mucous membranes. Typically, jaundice starts from the face and then spreads to the trunk and limbs. If the degree of jaundice is relatively severe, yellowing will appear on the entire body, including the ears. Generally, if the baby is visibly yellow, it is advisable to monitor the jaundice. If the jaundice value is significantly high and confirmed to be high in the blood, it is considered pathological jaundice, and it is recommended to seek timely intervention and treatment.
