2Care of Neonate with Neonatal Hyperbilirubinemia
3Hyperbilirbinemia
- Definition
- physiological jaundice
- the yellow discoloration of the skin,
conjunctivae, and sometimes mucous membranes - Occurs in more than 50 of all newborns
- (Deacon ONeill, 1999)
- affects full-term infants within 2 to 4 days of
birth and lasts until about day 6 (Kenner Lott,
2003) - preterm infants have higher peak levels occurring
at about 5 to 7 days of life (Kenner Lott,
2003) jaundice lasts longer in preterm infants
the more preterm an infant is the lower the
lightlevel
4Hyperbilirbinemia
- Pathophysiology
- Bilirubin is produced by the breakdown of
hemoglobin at the end of a red cells lifespan - Because the neonates liver is immature, the
bilirubin level exceeds the livers ability to
conjugate bilirubin (convert bilirubin to
soluble form for excretion) - This bilirubin then free floats in the plasma
- At high levels, bilirubin can cross the
blood-brain barrier and damage brain cells
causing kenicterus
5Hyperbilirubinemia
- Serum bilirubin levels (unconjugated) are greater
than 12 mg/dl and generally occurs after the
first 36 hours - A bili level above 12 mg/dl within the first 24
hours is not considered physiological - Bili levels in general are considered
physiological if - Full-term-12mg/dl or greater by 3 days of life
- Preterm-10 to 12 mg/dl or greater by 5 days of
life - Treatment depends on the bili level, the infants
gestational and actual age, and the severity of
the infants condition
6Causes of Hyperbilirubinemia
- (Kenner and Lott, 2003)
- ABO incompatibilities
- RBC breakdown
- Sepsis
- Drug reaction-such as Vitamin K
- Extravasation of large quantities of blood
- Bilirubin conjugation interference
- Breastmilk conjugation
7Causes of Hyperbilirubinemia
- (Kenner and Lott, 2003)
- Transplacental and neonatal drug interactions
- Hypothyroidism-affects up to 3 to 4 weeks
- Acidosis and hypoxia
- Decreased bowel motility or hepatocellular damage
can cause abnormal bilirubin excretion - Congestive heart failure can cause abnormal
bilirubin excretion
8What will you see in a jaundiced infant?
- Yellow discoloration that starts on the face and
spreads caudally - Yellow discoloration of the sclera and mucus
membranes - Signs and symptoms of kenicterus
9Hyperbilirubinemia
- Kenicterus is the yellow staining of brain tissue
and leads to brain damage, such as cerebral palsy
and deafness. - Kenicterus occurs in 50 of infants with bili
levels of 30 of greater and in 10 with bili
levels 20 to 25
10Hyperbilirubinemia
- Risk factors (Kenner and Lott, 2003)
- Inadequate intake/dehydration
- Acidosis and hypoxia
- Certain drugs and substances may compete with
available bilirubin binding sites such as
sufisoxazole, salicylates and sodium benzoate - Hypoproteinemia (lower albumin levels)-places
preterm infants at higher risks
11Hyperbilirubinemia
- Clinical manifestations of kenicterus
- usually evident in the first 5 days of life
- In a sick or preterm neonate, kenicterus can
occur at levels as low as 5 mg/dl (Nathan Oski,
1998)
12Hyperbilirubinemia
- Generally, the neonate is stable and otherwise
healthy - Because of early discharge, physiological
hyperbilirubinemia is often diagnosed in the home
care setting - Key to diagnosis is parent education
- Home phototherapy can be used
13Hyperbilirubinemia
- Treatment and management
- PREVENTION!!
- Double volume exchange transfusion
- Nursing Standard of Care Infant with Neonatal
Hyperbilirbinemia - Phototherapy
- Hydration
- Phenobarbital administration
14Phototherapy
- Phototherapy lights causes the bilirubin to
become more water-soluble this bilirubin can be
excreted in bile/stool and urine - May use bank lights and/or bili blanket
15Phototherapy
- Use bank lights and/or bili blankets
- Use bili mask to protect eyes.
- Monitor temperature closely by using continuous
skin temperature monitoring take temperature Q
2-4 hours - Bili levels at least every 8-12 hours, turning
off phototherapy lights with lab draws only
16Phototherapy
- Important to expose as much skin as possible,
covering only genitals and eyes for protection - Turn infant frequently to allow for maximum
exposure - Avoid use of ointments and lotions
17Phototherapy
- Important that the phototherapy light levels are
within acceptable range - Bilimeter readings q shift with approximate goal
of 25 to 45 (combined readings of biliblanket
and bili lights)
18Phototherapy
- Side effects-(Kenner and Lott, 2003)
- Parental teaching-signs and symptoms of
hyperbilirubinemia and dehydration - Dermal Rash
- Lethargy
- Abdominal distention
- Possible eye drainage
- Dehydration
- Thrombocytopenia
- Hypocalcemia
- Temporary lactose intolerance
- Bronze baby syndrome
19Nursing Standard of Care
- Patient will not experience neurological injury
- Assess and document skin color from head, sclera,
and trunk in daylight or under fluorescent light
at least q shift - Obtain bili levels as ordered
- Observe for and report abnormal neurological
findings - Check bilimeter readings
20Nursing Standard of Care
- Patient will not experience injury from
phototherapy - Cover eyes
- Inspect eyes q 2 hours and prn with phototherapy
lights off, notify physician of any drainage - Change eye shields prn
- Avoid tight head band on eye shield to reduce the
risk of increased ICP, especially in preterm
infants - Maximize exposed skin surface, protecting
genitalia - Avoid exposure of skin temperature probe to
phototherapy lights
21Nursing Standard of Care
- Patient will be adequately hydrated
- Maintain parenteral nutrition as ordered
- Encourage feedings ASAP, including breastfeeding
if held for feeds can discontinue overhead lights
for a short time and wrap biliblanket with
infant. - Accurate Is and Os
- Assess for signs of dehydration, account for
insensible water losses - Daily weights
22Nursing Standard of Care
- Patient will maintain thermoregulation
- Provide neutral thermal environment
- Maintain axillary temperature of at least 36.5
degrees Celsius - Avoid cold stress
- Q 4 hour vitals and prn
- Properly secure temperature probe to abdomen or
back
23Nursing Standard of Care
- The parents/caregivers will participate in the
childs care and health goals/outcomes - Provide information and explanations of
hyperbilirubinemia and phototherapy to the
parents/care givers - Explore with parents/caregivers their willingness
to provide care
24Phototherapy
- Follow-up Care
- Maintain adequate hydration, including enteral
feeds if possible - Check bili levels at least 4-8 hours after
phototherapy is D/Ced there is a chance for
rebound
25Exchange Transfusion
- Early exchange transfusion is indicated with the
presence of hemolytic disease - Carefully monitor fluid and electrolyte status
- Provide adequate hydration
26Exchange Transfusion
- Double volume Exchange Transfusion
- Purpose-to remove the infants bilirubin and
antibody-coated red blood cells from circulation
by removing the infants blood volume and
replacing the volume with blood or another volume
expander
27Phenobarbital Administration
- Increases the uptake and conjugation of bilirubin
by the liver and increasing its excretion by
increasing bile flow
28Care of the Neonate with Anemia
29Anemia
- Definition
- low hemoglobin concentration and/or decreased
number of red blood cells diminishes the
oxygen-carrying capacity of the blood and the
level of oxygen available to tissues (Blanchette
Zipursky, 1994 Hume, 1997 Miller, 1995
Oski, Brugnara, Nathan, 1998)
30Anemia
- Physiology
- removal or loss of 10 or more of total blood
volume over 24 to 48 hours can lead to anemia - In general, there are 100 ml of blood volume per
kg in a preterm infant and 82-85 ml of blood
volume per kg in a term infant (Kenner and Lott,
2003) - Hgb and HCT levels determine the type and degree
of anemia in general, Hct less than 40 is
considered anemia - Hgb may not accurately the extent of acute blood
loss - low HCT or Hgb may be acceptable if retic count
is NL
31Anemia
- Clinical findings
- Acute anemia-signs and symptoms are emergent and
life-threatening most common causes are
hemorrhage, RBC destruction and hemolysis, and
frequent blood sampling/draws - Chronic anemia in preterm and term infants
results from dietary deficiencies may not need
immediate intervention, but close monitoring for
signs of decompensation is necessary
32Anemia
- Risk factors and indications
- Frequent lab draws
- Family history of anemia or jaundice
- History of bleeding, splenectomy, consanguinity,
and/or blood group incompatibilities - Some ethnic groups and natives of specific
geographical origins, such as African-American
population and sickle cell anemia - Maternal history

of the transfusion) and after administration
(within 5 minutes of the end of the transfusion),
at 15 minutes of the start of the transfusion,
and every hour until transfusion is complete
47Transfusion Therapy
- If signs of transfusion reaction appear
- Stop transfusion immediately
- Immediately send transfused blood and
administration set to blood bank. - Follow instructions on report of transfusion
reaction form
48Anemia
- Long-term follow-up and prognosis
- Continue to assess for S/S of anemia
- Maintain adequate nutritional support
- Improved oxygenation and control or eradication
of symptoms are indicative of a positive
prognosis - Long-term prognosis is determined by the
underlying causes degree of anemia and the
infants response to interventions

74Care of the Neonate with DIC
75Disseminated Intravascular Coagulation
- Definition-an acquired hemorrhagic disorder with
an underlying disease manifested as an
uncontrollable activation of coagulation and
fibrinolysis. Consumption of clotting factors is
thought to be initiated by the release of
thromboplastic material from damaged or diseased
tissue into circulation. Fibrinogen converts to
fibrin to form microthrombi (Andrew, 1997
Beardsley and Nathan, 1998 Fuse et al, 1996
Hilgartner and Corrigan, 1995 Kuehl, 1997 Pugh,
1997 ). DIC presents with depletion of
