新生儿黄疸是临床常见的生理和病理现象,因血中胆红素升高导致。当足月儿总胆红素大于220.5μmol/L(12.9 mg/dl),早产儿大于256.6μmol/L(15 mg/dl)称为病理性黄疸。胆红素既有潜在的神经毒性,又有重要的抗自由基的生理作用。近年来逐渐认识到核黄疸是引起新生儿严重脑损伤及发 Neonatal jaundice is a common clinical physiology and pathology, due to elevated blood bilirubin. When full-term children with total bilirubin greater than 220.5μmol / L (12.9 mg / dl), preterm children more than 256.6μmol / L (15 mg / dl) is called pathological jaundice. Bilirubin both potential neurotoxicity, but also an important anti-free radical physiological role. In recent years, the gradual realization of nuclear jaundice is caused by severe neonatal brain injury and hair
