Jaundice in the full-term newborn.

Shortened hospital stays and inconsistent follow up are concerns for the welfare of all newborns. Infants of first time mothers who leave the hospital without well-established breastfeeding are at highest risk for re-admissions and complications from jaundice. Jaundice is a common problem affecting 60% of all full-term and 80% of preterm infants (Augustine, 1999). Jaundice describes the yellow orange hue of the skin caused by excessive circulating levels of bilirubin that accumulate in the skin (Parks, Montgomery, & Yetman, 2000).

In most healthy full-term newborns, jaundice is noticed during the first week of life and becomes noticeable at a bilirubin level of 5 mg/dl. Although uncommon, bilirubin toxicity occurs at bilirubin levels greater than 17 with possible long-term effects on brain cells (AAP, 2004; Harris, Bernbaum, Polin, Zimmerman, & Polin, 2001). With a greater understanding of jaundice and its treatment, nurses are able to closely monitor this common but potentially devastating condition, encourage breastfeeding, and provide optimal care and support for parents.

Pathophysiology of Jaundice

Bilirubin is formed from the breakdown of hemoglobin in red blood cells. Red blood cells (RBC) only live for 70-90 days in the newborn period, unlike the older child whose cells live 120 days (Berkowitz, 2000). Increased RBC destruction, decreased hepatic blood flow, and immature systems for breakdown of bilirubin causes jaundice in the newborn (Augustine, 1999; Berkowitz, 2000). The gastrointestinal tract (GI) in the newborn lacks the necessary bacteria to break down waste, increasing the reuptake of bilirubin (Berkowitz, 2000). Jaundice results from liver immaturity, obstruction of bile ducts, and excessive hemolysis.

Physiologic jaundice refers to jaundice in the immediate newborn period without signs of illness (Parks et al., 2000). In most newborns, total serum bilirubin levels peak between the second to fourth day of life. Early discharge from the hospital of infants less than 48 hours of age, without appropriate and timely follow up, has significantly increased the numbers of newborn re-admissions for management of hyperbilirubinemia (Harris et al., 2001). In addition, incidence of acute bilirubin encephalopathy and kernicterus have increased among otherwise healthy breastfed infants with poor feeding and delayed follow up visits (AAP, 2004; Harris et al., 2001).

Kernicterus is a pathologist's term describing the yellow deposits and brain cell death from extremely high levels of bilirubin, generally >25-30 mg/dl. The term is often used interchangeably with bilirubin encephalopathy. Kernicterus denotes chronicity of this condition and can be seen with magnetic resonance imaging. It is frequently associated with G6PD Dehydrogenase Deficiency (AAP, 2004; Hayes, 2000; Schwoebel & Sakraida, 1997). Acute bilirubin encephalopathy is used to describe the clinical disorder with signs of stupor, hypotonia/extensor hypertonia, poor feeding, and fever. Sequelae include cerebral palsy with athetosis (involuntary writhing movements), oculomotor damage, and high frequency hearing loss (Hayes, 2000). One study concluded that although infrequent, kernicterus has at least 10% mortality and over 70% long-term morbidity (Stanley et al., 2004). Of interest, bilirubin is thought to have some beneficial antioxidant effects at normal levels and has sparked new interest in jaundice research (Greenberg, 2002; Schwoebel & Sakraida, 1997). Laboratory studies in rats are ongoing to determine the significance of bilirubin in oxidative injury with potential benefit in stroke and Alzheimer's disease prevention.

Newborns who are breastfed are three times more likely to have total bilirubin levels >12 mg/dl than bottle-fed infants as there may be considerable delay before breastfeeding is well established (Augustine, 1999). Bilirubin is primarily excreted through the bowel. Colostrum aids in the evacuation of meconium, the infant's first stools, thereby reducing the enterohepatic circulation of bilirubin (Hayes, 2000). Inadequate caloric intake and subsequent weight loss, delayed passage of stool, and bruising from delivery place the infant at high risk for jaundice (Hayes, 2000). In addition to physiologic jaundice, many conditions are associated with hyperbilirubinemia such as sepsis, twin-to-twin transfusion, hemolysis from Rh incompatibility, and slowed excretion of bilirubin seen with hypothyroidism and cystic fibrosis (Augustine 1999; Berkowitz 2000).

Clinical Features

The nurse obtains a thorough pregnancy and birth history. The history includes family history of congenital disorders such as cystic fibrosis and family history of blood disorders or jaundice. Documentation includes maternal disease such as diabetes, presence or exposure to infection, and maternal hepatitis vaccination. Pregnancy history includes gestational age, maternal blood type, and Rh and isoimmune antibody titers. It is important to note the presence of newborn trauma such as cephalohematoma, adequacy and number of feedings, infant output including the color of stools, presence of temperature instability, and the time of onset of jaundice as well as associated symptoms such as vomiting or delayed stooling.

Black infants tend to have lower levels of bilirubin than whites with an average peak for both on the third day of life. Asian and Native American infants tend to have higher levels, which peak on the fourth to fifth day with a longer duration (Hayes, 2000). Persistent early high levels of bilirubin should prompt investigation for G6PD deficiency found in individuals from the Mediterranean and Middle East, Arabian peninsula, Southeast Asia, and Africa.

The family of an infant with significant jaundice often reports a sleepy infant who does not take well to the breast. A gradual increase in jaundice may go unnoticed. Jaundice appears in a cephalocaudal manner, first seen on the newborn face and sclera and progressing to the trunk, arms, and lower extremities. Visual examination of the infant is not a reliable measure of jaundice and should be verified with transcutaneous bilirubinometry (TCB) and/or serum bilirubin testing (AAP, 2004; Moyer, Ahn, & Snead, 2000). The AAP (2004) recommends term infants with TCB greater than 19 measured on the sternum have a serum bilirubin level checked as well. TCB is a screening tool with some question of its reliability and should not be used in preterm infants, infants receiving phototherapy, or in non-Caucasian infants (AAP, 2004).

End-tidal carbon monoxide (ETCOc) level is new technology used in some neonatal intensive care units to confirm the presence of hemolysis. The measurement of ETCOc is the only clinical test that provides a direct measurement of the rate of heme catabolism and the rate of bilirubin production. It is too early to tell how this test, which currently is not widely available, will affect management (AAP, 2004).

Physical assessment of the infant with jaundice includes observing for signs of sepsis, which may contribute to jaundice, such as poor feeding, apnea, hypothermia, bruising, petechiae, and cephalohematoma. The nurse notes the presence of lethargy, vomiting, tenderness in the right upper quadrant, excessive weight loss, hepatosplenomegaly, dark urine or pale white stools (acholic stools suggest biliary atresia), and rashes. Ocular anomalies, hearing deficits, unusual facial features, and cardiac defects suggest a genetic syndrome (Berkowitz, 2000).

The onset of significant jaundice in the first 24 hours of life is not considered a normal finding and deserves careful monitoring. Table 1 describes risk factors for jaundice and factors suggesting a pathologic cause of jaundice.

There are many causes of jaundice other than physiologic jaundice, which the health care provider needs to be familiar. Table 2 gives a brief summary of the differential diagnosis of jaundice.

Diagnosis

The AAP (2004) suggests measurement of total, direct, and indirect bilirubin levels as appropriate, and if direct bilirubin is less than 1.5, then one may follow total bilirubin. Indirect bilirubin levels measure "free" or unconjugated bilirubin and direct bilirubin levels measure conjugated bilirubin (Pagana & Pagana, 2002). Conjugation refers to the pairing of bilirubin with intracellular proteins in the liver. Conjugated bilirubin is water-soluble and eliminated by the kidneys and GI tract (Berkowitz, 2000). Free floating or unconjugated bilirubin has a greater chance of being reabsorbed and thus raising blood levels as well as potentially crossing the blood brain barrier causing damage (Schwoebel & Sakraida, 1997).

Laboratory studies for the newborn with jaundice include a total and direct bilirubin level, newborn cord blood type, Rh and screen (indirect Coomb's) and direct Coomb's test if not done previously by the facility (AAP, 2004; Alexander & Robin, 2000). The direct and indirect Coomb's tests detect antibodies against RBC seen in ABO/Rh incompatibility that may cause cellular damage and hemolytic anemia (AAP, 2004; Pagana & Pagana, 2002). Complete blood count with differential, platelet count, albumin (to aid in assessment of unbound bilirubin), blood culture, urinalysis, and peripheral smear to rule out infection and hemolysis may be warranted. A reticulocyte count may be useful if the infant is anemic to measure red blood cell production by the bone marrow. Family history of G6PD deficiency or hemolytic disease requires further evaluation. All blood work including chromosomal studies must be completed before exchange transfusion (Alexander & Robin, 2000). Parks et al. (2000) summarizes laboratory findings for hyperbilirubinemia:

* Elevated serum indirect bilirubin with normal reticulocyte count and negative Coomb's test is associated with physiologic, breast milk jaundice, or familial nonhemolytic jaundice.

* Elevated serum indirect bilirubin with increased reticulocyte count is indicative of increased hemolysis seen with ABO/Rh incompatibility and red blood cell abnormalities.

* Elevation of both direct and indirect bilirubin with a negative Coomb's test and normal reticulocyte count is indicative of hepatitis, metabolic or obstructive disorders, or sepsis.

In addition to phenylketonuria, many metabolic diseases including hypothyroidism are tested in the nursery prior to discharge. Testing urine for reducing substances offers a quick evaluation method for galactosemia (AAP, 2004; Berkowitz, 2000). Another rapid test for conjugated hyperbilirubinemia is noting a yellow color to the foam of a shaken tube of urine; the challenge, of course, is in obtaining the sample (Berkowitz, 2000). Liver function studies are appropriate when the direct bilirubin is >2 mg/dl, if the provider suspects hepatitis or if hepatomegaly is present.

Several new methods of evaluating jaundice are available but not widely used. Noninvasive transcutaneous bilirubinometry offers a more objective measure of jaundice than visual estimates, which are not recommended (AAP, 2004; Hayes, 2000). Expired carbon monoxide levels, a byproduct of bilirubin breakdown, also are being used in some facilities to evaluate the presence of hemolysis (AAP, 2004; Schwoebel & Sakraida, 1997).

Table 3 helps delineate the causes of conjugated and unconjugated hyperbilirubinemia.

Treatment

Treatment of jaundice includes encouraging frequent breastfeeding, phototherapy using overhead and/or fiberoptic pads, medication, and exchange transfusion.

Non-pharmacologic treatment. Non-

pharmacologic treatment includes frequent breastfeeding and phototherapy when warranted. It is recommended that mothers breastfeed their newborns 8-12 times per day during the first 3 days of life to prevent significant jaundice (AAP, 2004; Hayes, 2000). The AAP supports breastfeeding with the addition of expressed breast milk or formula supplementation only when the milk supply is inadequate, or the infant experiences excessive weight loss (< 7%) or shows signs of dehydration. Intravenous fluids and water supplementation do not lower the bilirubin level significantly and are unnecessary in the infant who is adequately hydrated (AAP, 2004; Augustine, 1999; Hayes, 2000). The AAP recommends formal evaluation of breastfeeding at 24-48 hours of life with follow up 48-72 hours after discharge. Early evaluation affords the provider the opportunity to correct problems and help mothers establish and maintain breastfeeding.

Adequate milk intake for the newborn is evidenced by six urine saturated diapers and three stools per day (AAP, 2004; Hayes, 2000). After the infant returns to birth weight, one would expect a gain of approximately one-half to one ounce per day. Occasionally breastfeeding must be temporarily halted for 24-48 hours when jaundice is prolonged due to substances in the breast milk. Breastmilk jaundice has a later onset, as late as the fifth day, and may last several weeks. Some authorities advocate temporary cessation of breastfeeding, which causes a rapid decline in bilirubin levels. However, this action is usually unnecessary and is not used as a diagnostic maneuver. Bilirubin levels tend to rise slightly after breastfeeding is resumed but do not return to the same high level (Hayes, 2000).

The first line of treatment after increasing number of feeds is phototherapy, which uses a special artificial blue light to alter bilirubin so it may be excreted in the urine and stool (AAP, 2004; Augustine, 1999). A low serum albumin level of less than 3.0 g/dL is considered a factor in deciding when to initiate phototherapy (AAP, 2004). Regular sunlight does not lower bilirubin as rapidly, exposes the infant to potential sunburn, and is not recommended. Fiberoptic pads may be used alone for the infant with mild jaundice or in addition to overhead phototherapy for the infants with higher bilirubin levels. These pads allow the infant to be held and fed more readily without interruption of therapy and with less risk of temperature instability. Fiberoptic pads may be used in home management of an infant with a mild degree of jaundice with in-home nursing visits and serum bilirubin monitoring.

Traditional overhead phototherapy placed within 15-20 cm of infant has been found to decrease the bilirubin level 1-2 mg/dl in the first 4-6 hours with continued decreases (AAP, 2004; Hayes, 2000) (see Table 4 for guidelines). When bilirubin levels are steadily decreasing, < 14 mg/dl, and feeding is well established, phototherapy may be discontinued.

With both types of phototherapy, the nurse monitors temperature stability, skin integrity, and fluid and weight loss. The newborn's eyes and genitals are protected from the light. Specially designed eye patches are made just for this purpose. As of this writing, no research studies address coverage of infant genitalia, but it has long been standard practice to cover the genitals with a modified diaper or mask. Staff monitor for signs of eye irritation. Infants with severe cholestatic jaundice are monitored for purpura and bullous eruptions while receiving phototherapy (AAP, 2004).

Pharmacologic treatment. Medication for jaundice is rarely used. Phenobarbital has been shown to decrease bilirubin levels by increasing excretion by the liver (Hayes, 2000). This therapy is not routinely used for newborns with direct hyperbilirubinemia as it must be administered over as many as 6 days; however, it is useful in children with Crigler-Najjar syndrome type II (Berkowtiz, 1996; Hayes, 2000).

The use of agar, tin protoporphyrin, zinc or tin mesoporphyrin and herbal products continues to be researched. Tin mesoporphyrin, inhibits the production of heme oxygenase and, when approved by the U.S. Food and Drug Administration, could prevent the need for exchange transfusion in infants who are not responding to phototherapy (AAP, 2004).

Infants with isoimmune hemolytic disease may benefit from intravenous-globulin (0.5-1 g/kg over 2 hours) if the total serum bilirubin is rising despite intensive phototherapy or approaching the need for exchange transfusion (AAP, 2004). Intravenous-globulin has been shown to reduce the need for exchange transfusions in Rh and ABO hemolytic disease. Monitoring and treatment of sepsis is essential to resolving hyperbilirubinemia as quickly as possible.

Exchange transfusion. Exchange transfusion is seldom used but is indicated when bilirubin levels reach 25-30 mg/dl and to correct anemia in infants severely affected by hemolytic process. Exchange transfusion is considered at lower levels in infants with hemolytic disease, sepsis, prior hypoxia, hypoglycemia, prematurity, and infants who do not respond to intensive phototherapy or have a rapid rise in bilirubin (AAP, 2004; Hayes, 2000). Immediate exchange transfusion is recommended in any infant who is jaundiced with signs of the acute bilirubin encephalopathy including hypertonia, arching, retrocollis and opisthotonos (head and heels drawn back), fever, and high-pitched cry--even if the bilirubin is decreasing (AAP, 2004) (see Table 4).

Exchange transfusion lowers bilirubin by nearly 50% but also has risks. Infants receiving exchange transfusion are given fresh blood that is irradiated to lower the risk of graft versus host reaction (signs: maculopapular rash, eosinophilia, leukopenia, thrombocytopenia), and hyperkalemia. Citrate in the blood may cause disturbance in calcium and magnesium levels and acidosis. Rebound hypoglycemia is also a risk that occurs 1-2 hours post transfusion. Lastly, hypothermia, hemodynamic instability, sepsis, thrombosis, necrotizing enterocolitis, bleeding, and HIV are risks of exchange transfusion (AAP, 2004).

Nursing Interventions

Nurses are aware that confirmation of capillary bilirubin by venous sampling is not necessary and should not delay treatment of jaundice (AAP, 2004). The first line of treatment for most infants with jaundice requiring intervention is phototherapy. The infant receiving phototherapy requires extra attention and care to the placement of lights to be therapeutic yet prevent chilling or burning the infant. Some infants may also benefit from a fiberoptic pad underneath them, especially in the breastfed infant who is encouraged to feed 8-12 times in 24 hours. Supplements are not normally needed and are discouraged as they interfere with breastfeeding. Infants in incubators may not receive the full benefit of phototherapy. Light irradiance should be measured and maintained according to hospital policy and an average reading from several areas above the infant recorded.

Nurses carefully document intake and output. Diapers of preterm or high-risk infants are weighed. All infants should be weighed unclothed daily, preferably on the same scale. Infants may develop skin breakdown when diapers are not used and become chilled if left on wet sheets. Therefore, linens should be changed frequently, ideally with each void.

Nursing assessment includes evidence of birth trauma, head size and presence of cephalohematoma, tachypnea, dyspnea, enlarged liver, lethargy, irritability, feeding and stooling, sleep patterns, and interaction with family. These observations are communicated with the nurse practitioners and physicians caring for these infants, as well as other nursing staff, to improve quality and continuity of care.

Serum bilirubin levels above 25 mg/dL or higher at any time is a medical emergency and the infant should be evaluated immediately for exchange transfusion (AAP, 2004) (see Table 4). Infants receiving exchange transfusions receive individualized care in neonatal intensive care as the procedure is very time consuming and the infant needs close monitoring. Infants returning to the hospital after discharge with jaundice should not be detained in the emergency department as treatment may be delayed (AAP, 2004).

Patient Education and Counseling

Families of newborns with jaundice need to be included in and well informed of the plan of care. They may feel inadequate and guilty especially if the infant requires prolonged hospitalization. Frequent breastfeeding 8-12 times or more in 24 hours is encouraged and supported by the nurse and through the use of staff trained in lactation. Families are taught that additional supplementation with water or formula is not necessary for the healthy infant and may interfere with breastfeeding. Parent education includes use of a breast pump and milk storage if the mother is discharged before her infant, which is helpful for mothers anticipating return to work after the postpartum period. A contact person for lactation information and evaluation is made readily available.

Home health services that feature extensive education and daily visits may be used for home phototherapy for low risk selected infants. Parents should be discouraged from placing their infant in sunlight as it may cause chilling and unnecessary eye and skin exposure. Lastly, parents should be instructed to avoid using herbal remedies for their newborn infant (see Table 5 for a parent-information handout, which is available in English, Spanish, Chinese, and Italian at www.aap.org/family/jaundice faq.htm).

Follow-up

Newborns with hyperbilirubinemia need close observation and follow up. Hospital readmission may be necessary to manage complications and for closer observation of newborns that are poor feeders, have lost significant weight, or have signs of dehydration or bilirubin encephalopathy. Infants with serum bilirubin levels >5 mg/dl in the first 24 hours of life and older infants with levels >12-14 mg/dl need close lab monitoring and thorough evaluation (AAP, 2004; Hayes, 2000).

Recommendations for follow up vary according to length of hospital stay and presence/severity of jaundice. Clinical evaluation of all newborn infants 48-120 hours after discharge and again at 2-4 weeks after birth is recommended. Infants who received phototherapy in the hospital or are receiving home phototherapy should be followed 24 hours after discharge (AAP, 2004; Hayes, 2000; Maisels & Kring, 2002). Direct bilirubin levels are checked daily in newborns with significant jaundice; the frequency of laboratory studies is left to the discretion of the provider.

* Intensive phototherapy should produce a decline of TSB of 1 to
2 mg/dL with-in 4 to 6 hours and the TSB level should continue to
fall and remain below the threshold level for exchange transfusion.
If this does not occur, it is considered a failure of phototherapy.

* Term infants who are clinically jaundiced at <=24 hours old are not
considered healthy and require further evaluation.

* Preterm infants should receive exchange transfusion when level
reaches infant's weight ie: 11 mg/dl in 1100-g infant
(Berkowitz, 2000).

Congratulations on the birth of your new baby!
To make sure your baby's first week is safe and healthy, it is
important that:

1. Your baby is checked for jaundice in the hospital.

2. If you are breastfeeding, you get the help you need to
make sure it is going well.

3. Your baby is seen by a doctor or nurse at 3 to 5 days of
age.

Q: What is jaundice?

A: Jaundice is the yellow color seen in the skin of many
newborns. It happens when a chemical called bilirubin
builds up in the baby's blood. Jaundice can occur in
babies of any race or color.

Q: Why is jaundice common in newborns?

A: Everyone's blood contains bilirubin, which is removed by
the liver. Before birth, the mother's liver does this for the
baby. Most babies develop jaundice in the first few days
after birth because it takes a few days for the baby's liver
to get better at removing bilirubin.

Q: How can I tell if my baby is jaundiced?

A: The skin of a baby with jaundice usually appears yellow.
The best way to see jaundice is in good light, such as
daylight or under fluorescent lights. Jaundice usually
appears first in the face and then moves to the chest,
abdomen, arms, and legs as the bilirubin level increases.
The whites of the eyes may also be yellow. Jaundice may
be harder to see in babies with darker skin color.

Q: Can jaundice hurt my baby?

A: Most infants have mild jaundice that is harmless, but in
unusual situations the bilirubin level can get very high
and might cause brain damage. This is why newborns
should be checked carefully for jaundice and treated to
prevent a high bilirubin level.

Q: How should my baby be checked for jaundice?

A: If your baby looks jaundiced in the first few days after
birth, your baby's doctor or nurse may use a skin test or
blood test to check your baby's bilirubin level. A bilirubin
level is always needed if jaundice develops before the
baby is 24 hours old. Whether a test is needed after that
depends on the baby's age, the amount of jaundice, and
whether the baby has other factors that make jaundice
more likely or harder to see.

Q: Does breastfeeding affect jaundice?

A: Jaundice is more common in babies who are breastfed
than babies who are formula-fed, but this occurs mainly
in infants who are not nursing well. If you are breastfeeding,
you should nurse your baby at least 8 to 12
times a day for the first few days. This will help you produce
enough milk and will help to keep the baby's bilirubin
level down. If you are having trouble breastfeeding,
ask your baby's doctor or nurse or a lactation specialist
for help. Breast milk is the ideal food for your baby.

Q: When should my newborn get checked after
leaving the hospital?

A: It is important for your baby to be seen by a nurse or
doctor when the baby is between 3 and 5 days old,
because this is usually when a baby's bilirubin level is
highest. The timing of this visit may vary depending on
your baby's age when released from the hospital and
other factors.

Q: Which babies require more attention for jaundice?

A: Some babies have a greater risk for high levels of bilirubin
and may need to be seen sooner after discharge
from the hospital. Ask your doctor about an early follow-up
visit if your baby has any of the following:

* A high bilirubin level before leaving the hospital

* Early birth (more than 2 weeks before the due date)

* Jaundice in the first 24 hours after birth

* Breastfeeding that is not going well

* A lot of bruising or bleeding under the scalp related
to labor and delivery

* A parent or brother or sister who had high bilirubin
and received light therapy

Q: When should I call my baby's doctor?

A: Call your baby's doctor if:

* Your baby's skin turns more yellow.

* Your baby's abdomen, arms, or legs are yellow.

* The whites of your baby's eyes are yellow.

* Your baby is jaundiced and is hard to wake, fussy, or
not nursing or taking formula well.

Q: How is harmful jaundice prevented?

A: Most jaundice requires no treatment. When treatment
is necessary, placing your baby under special lights
while he or she is undressed will lower the bilirubin
level. Depending on your baby's bilirubin level, this can
be done in the hospital or at home. Jaundice is treated
at levels that are much lower than those at which brain
damage is a concern. Treatment can prevent the harmful
effects of jaundice.

Putting your baby in sunlight is not recommended as a
safe way of treating jaundice. Exposing your baby to
sunlight might help lower the bilirubin level, but this
will only work if the baby is completely undressed. This
cannot be done safely inside your home because your
baby will get cold, and newborns should never be put
in direct sunlight outside because they might get sunburned.

Q: When does jaundice go away?

A: In breastfed infants, jaundice often lasts for more than
2 to 3 weeks. In formula-fed infants, most jaundice goes
away by 2 weeks. If your baby is jaundiced for more
than 3 weeks, see your baby's doctor.
