Transcript

  • 1. Neonatal Jaundice Manaen
  • 2. Framework • The definition of Neonatal Jaundice • Billirubin Metabolism • Special characteristic in neonates • Dangerous of the Hyperbillirubinemia • The diseases in relation with Neonatal Jaundice
  • 3. What is the Neonatal Jaundice? • Neonatal Jaundice(also called Newborn jaundice) is a condition marked by high levels of bilirubin in the blood. The increased bilirubin cause the infant's skin and whites of the eyes (sclera) to look yellow.
  • 4. Billirubin Metabolism
  • 5. Special characteristic in neonates • 1.More billirubin produced • Much more Hemolysis • The life-length of hemolysis(70~80)
  • 6. Special characteristic in neonates • 2.The low capability of albumin on unconjugated billirubin transportation • acid intoxication • Less albumin in neonates
  • 7. Special characteristic in neonates • 3.The low capability of heptatocyte • Less Y protein and Z protein • The primary development of Hepato- enzyme system • Easy-broken hepato-enzyme system • After-born, the blood glucose level is very low.
  • 8. Special characteristic in neonates • 4.High workload of the hepato-enteric circulation • Less bacterial • Low enzymatic activity in intestine • High level of billirubin in meconium
  • 9. A little exam Increased rbc’s Shortened rbc lifespan Immature hepatic uptake & conjugation Increased enterohepatic Circulation
  • 10. The general symptom of neonatal jaundice • Yellow skin • Yellow eyes(sclera) • Sleepiness • Poor feeding in infants • Brown urine • Fever • High-pitch cry • Vomiting
  • 11. Brown urine
  • 12. Grading of extent of jaundice 1 Area of body Billirubin levels mg/dl (*17=umol) Face 4-8 Upper trunk 5-12 Lower trunk & thighs 8-16 Arms and lower legs 11-18 Palms & soles > 15
  • 13. Grading of extent of jaundice 2
  • 14. Hemolytic disease of newborn This condition occurs when there is an incompatibility between the blood types of the mother and baby.
  • 15. Are they use the same circulation system?
  • 16. Placental barrier • ..
  • 17. The blood types(A, B, O, AB) • Although it is not as common (especially in a first pregnancy), a similar problem of incompatibility may happen between the blood types (A, B, O, AB) of the mother and baby in the following situations:
  • 18. The blood types(A, B, O, AB)
  • 19. The blood types (Rh)
  • 20. Kernicterus • Kernicterus is damage to the brain centers of infants caused by increased levels of unconjugated-indirect bilirubin which is free (not bound to albumin).
  • 21. Blood-brain barrier
  • 22. The symptoms • Eye movement obstacles • Hearing disorder
