25. On Discharge
• Serum bilirubin level was several squares
below photo therapy level.
• Very mild jaundice was present.
• Baby was active and feeding well

26. Neonatal Jaundice
Yellowish discoloration of skin and sclera
Clinically jaundiced when bilirubin level
reach about 80µmol/ l

27. • Usually over 50% of all new born infants become visibly
jaundiced because of,
 High [Hb] at birth RBC breakdown
 RBC life span of infants are short(70 days)
 Less efficient bilirubin metabolism
Early neonatal jaundice is important :
# as it may be a sign of another disorder;
Eg: Haemolytic anaemia
Infection
Metabolic disease
Liver disease
# Unconjugated bilirubin deposition in basal ganglia may
cause Kernicterus

28.  In the neonate, defect in any of the above steps can give rise
to problems
Bilirubin
metabolism

29. Types of Jaundice
A. Physiological Jaundice
• Jaundice can be seen in 60% of Term infants & 80% of
Preterm infants.
• It is mostly physiological
Features of physiological jaundice: (ALL of the following)
 Jaundice that first appears between 24-72 hours of age
 Maximum intensity is seen on 4-5th day in term and 7th day
in preterm neonates
 Usually mild and less than 15mg/dl
 Clinically undetectable after 14 days
 Physiological jaundice is a diagnosis by exclusion.no
treatment is required but baby should be observed closely
for signs of worsening jaundice.

30. B. Pathological Jaundice
Features of pathological jaundice: ( ANY of the
following)
 Clinical jaundice within 24 hours of birth
 Total serum bilirubin (TSB) increase by >5mg/dl/day
(85µmol/l/day) OR 0.5mg/dl/hour (8.5µmol/l/hour)
 Conjugated serum bilirubin >20% of total serum
bilirubin level.
 Clinical jaundice persisting for > 2 weeks* in full term
and >3 weeks in preterm neonates (prolong
jaundice). (*NB : except in cases of breast milk
jaundice)

31. Causes of Jaundice
• Hyperbilirubinaemia in the first week of life is usually of the
unconjugated (Indirect) variety.
• Although conjugated hyperbilirubinaemia (Direct) occurs less
commonly , it is always pathological.
Appearing within 24 hours of age ;
 Haemolytic disease of newborn –
Blood group incompatibility - ABO ,Rh and minor blood
group incompatibility
Hereditary hemolytic anaemias -
Congenital spherocytosis
G6PD deficiency
 Infections –perinatal sepsis

32. Appearing after 24 hours after life ;
All of the above
Physiological
Polycythemia
Concealed haemorrhages- Subneurotic
/subarachnoid/intraventricular haemorrhage

33. Prolonged jaundice (In term babies > 2 weeks)
(In pre term babies > 3 weeks)
A.Prolong Unconjugated hyperbilirubinaemia:
 New or persisting sepsis- eg: UTI
 Metabolic –Hypothyroidism , Galactosaemia
 Persisting haemolysis
 Breast milk jaundice
B. Prolonged Conjugated hyperbilirubinaemia:
 Neonatal hepatitis -
Congenital infections
Intrauterine infections (TORCH)
α1 antitrypsin deficiancy
 Extra hepatic biliary atresia
 Choledochal cyst
 Metabolic disorders-
Eg: Galactocaemia
Crigler Najjar Syndrome

34. Assessment of a jaundiced within the
1st week
• This is directed towards assessing the severity,
complications and determining the aetiology of
jaundice.
Severity of jaundice
• Jaundice in the newborn progresses in the cephalo-
caudal direction and thus the extent of yellowness of
the skin is useful to assess the level of bilirubin.
• When a neonate is clinically jaundiced, the TSB is
usually >5 mg/dl (85 μmol/l).
• Serum bilirubin profiles and transcutaneous methods
• Kramer’s criteria are used to clinically estimate severity

35. Kramer’s Criteria
1 or less - >10mg/dl
2 or less - >15mg/dl
5 – definitely need
interventions
These values are not
absolute

36. Management
• Mx of jaundice is directed towards reducing the level of
bilirubin and preventing CNS toxicity.
1. Reduction of bilirubin is achieved by phototherapy
and / or exchange transfusion.
2. Dilution of bilirubin by giving FFP, fluids.
3. Hyperbilirubinaemia due to dehydration may be
prevented by early and frequent feeding.
The decision to treat depends on the severity and the
cause of jaundice.

37. Phototherapy
Preparation for phototherapy
• This involves exposure of the naked baby to blue-green
spectrum of wave length 450-460nm
• kept about 18 inches away from the light.
• The light waves convert the bilirubin to water soluble
nontoxic forms which are then easily excreted.
• Frequent feeding, every 2-3 hours and change of
posture should be promoted in an infant receiving
phototherapy.
• Eye shades should be fixed.
• External genitalia should be covered

38. Provision of phototherapy
 Degree of phototherapy depends on severity of jaundice
 Initiate continuous multiple phototherapy if any of the
following apply;
• TSB level is rising> 0.5 mg/dl/hr
• TSB is at a level within 3mg/dl below the level for which
exchange transfusion is indicated
• TSB level fails to respond to single phototherapy
• When bilirubin level falls during continuous multiple
phototherapy to a level > 3mg/dl below the threshold level
for which exchange transfusion is indicated , step down.
 Repeat serum bilirubin measurement 4–6 hours after
initiating phototherapy and continue 6hrly if rising or non
responsive or 12hrly if responsive.

39. Side effects of phototherapy
• Increased insensible water loss when providing
phototherapy in cots: breastfeed more frequently / provide
adequate fluids to avoid dehydration
• Loose green stools: weigh often and compensate with
breast milk.
• Skin rashes: harmless, no need to discontinue
phototherapy;
• Bronze baby syndrome: occurs if baby has conjugated
hyperbilirubinaemia. If so, discontinue phototherapy
• Hypo or hyperthermia: monitor temperature frequently.
• Damage to eyes: cover eyes

40. Exchange Transfusion
• should be performed if the TSB remains in
exchange transfusion range as per treatment
threshold graphs, despite effective phototherapy.
• Immediate exchange transfusion is indicated if
features of bilirubin encephalopathy are evident.
• Delay in treatment may result in permanent brain
damage.
• When referring a baby with jaundice, make sure
that either the mother is referred or mother’s
blood sample is sent.

41.  Use a double-volume exchange transfusion (2
x 80 ml /kg)
 Umbilical vessels are the preferred access
method for performing an exchange
transfusion
 Electrolytes, blood gases and vital signs should
be monitored during exchange transfusion

42. Type of blood
• In ‘Rh’ isoimmunisation, the best choice would be O
negative packed cells suspended in AB positive plasma.
O negative whole blood or cross-matched baby’s blood
group (but Rh negative) may also be used.
• For ‘ABO’ isoimmunisation, O group (Rh compatible)
packed cells suspended in AB plasma or O group whole
blood (Rh compatible with baby) should be used.
• In other situations baby’s blood group should be used.
All blood must be cross matched against maternal
plasma.
