What are the reasons?Many newborn babies will have problems jaundice, neonatal jaundice reason that you know what are you?The following night on the net to tell you exactly what the cause of neonatal jaundice。
Neonatal jaundice reasons (a) physiological characteristics of neonatal jaundice and bilirubin metabolism related, including bilirubin generate relatively large; insufficient liver cell uptake of bilirubin; the ability to join serum albumin bilirubin difference ; bilirubin excretion defects; increased enterohepatic circulation。Thus 60% and 80% of full-term children preterm children jaundice visible in the first week after birth。(B) jaundice 1.Bilirubin due to overproduction and excessive increase in enterohepatic circulation destruction of red blood cells, serum unconjugated bilirubin。
Common cause: polycythemia, extravascular hemolysis, autoimmune hemolytic same family, infection, increased enterohepatic circulation, erythrocyte enzyme defects, abnormal red blood cell morphology, hemoglobin disease, E deficiency, and hyperlipidemia and other low zinc。
Neonatal jaundice Cause 2.Hepatic bilirubin metabolism disorders due to low liver uptake and cell binding function of bilirubin, unconjugated serum bilirubin。Common causes are: infection and hypoxia, Crigler – Najjar syndrome (congenital uridine diphosphate glucuronic acid transferase deficiency), Gilbert syndrome (congenital non-hemolytic unconjugated bilirubin Synptom), Lucey- Driscoll syndrome (familial transient neonatal jaundice), a drug (e.g. sulfonamides, salicylates, indomethacin, lanatoside C class), congenital hypothyroidism, hypopituitarism, trisomy 21 and other。
