Pediatric jaundice, mostly seen in newborns/early childhood, manifests as yellowing of the skin of the facial trunk, mucosa sclera and other tissues. The clinical manifestations of jaundice are as follows: 1. Scleral yellow staining. Whether it is physiological jaundice, or pathological jaundice, the most likely to appear is scleral yellowing, which is the most sensitive part of the body yellowing, but also the most easily detected parts, this part contains a large amount of elastic hard protein, more easily combined with the bilirubin inside the blood, so to appear earlier than other parts of the body yellowing. 2. Yellow staining of the skin all over the body. This can be seen in the oral mucosa, face, trunk and extremities of the body. Physiological jaundice, the degree of jaundice is generally not deep, the skin color is light yellow, jaundice is often limited to the face and upper body; while pathological jaundice, the degree of jaundice is too heavy, often spread throughout the body and the heart of the hands and feet, and the skin mucous membrane is obviously yellow, some children’s skin can become dark yellow. 3, high transcutaneous jaundice value. For children, a transcutaneous jaundice value of 5 mg/dl or less is normal, and when the transcutaneous jaundice value is greater than 5 mg/dl, it suggests the presence of jaundice. When the transdermal jaundice value is greater than 12.9 mg/dl or higher than the daily bilirubin increase value, it is necessary to actively seek medical treatment. 4. High blood bilirubin values. Jaundice visible to the naked eye can occur when the total blood bilirubin value of a child is greater than 85umol/L. Neonatal jaundice, need to pay attention to, do not lose the baby because of small, causing a variety of secondary damage to the baby.
