Management of Hyperbilirubinemia Encourage frequent feedings Exposure to sunlight Phototherapy Shield infant’s eyes Monitor body temperature Monitor weight Monitor fluid intake Weigh diapers Note frequency of stools

Physiologic Hyperbilirubinemia Appears after first 24 hours of life Disappears within 14 days Due to an increase in red cell mass

Pathologic Hyperbilirubinemia Appears within first 24 hours of life Serum bilirubin concentration rises by more than 0.2 mg/dL per hour Bilirubin concentrations exceed the 95th percentile Conjugated bilirubin concentrations are greater than 2 mg/dL Clinical jaundice persists for more than 2 weeks in a term newborn

Causes of Pathologic Hyperbilirubinemia Hemolytic disease of the newborn Erythroblastosis fetalis Hydrops fetalis ABO incompatibility

Treatment of Pathologic Hyperbilirubinemia Resolving anemia Removing maternal antibodies and sensitized erythrocytes Increasing serum albumin levels Reducing serum bilirubin levels Minimizing the consequences of hyperbilirubinemia

Phototherapy: Nursing Care Maximize exposure of the skin surface to the light Periodic assessment of serum bilirubin levels Protect the newborn’s eyes with patches Measure irradiance levels with a photometer Good skin care and reposition infant at least every 2 hours Maintain an NTE and adequate hydration and nutrition

Cold Stress Increase in oxygen requirements Increase in utilization of glucose Acids are released in the bloodstream Surfactant production decreases

Figure 33–13 Cold stress chain of events Figure 33–13 Cold stress chain of events. The hypothermic, or cold-stressed, newborn attempts to compensate by conserving heat and increasing heat production. These physiologic compensatory mechanisms initiate a series of metabolic events that result in hypoxemia and altered surfactant production, metabolic acidosis, hypoglycemia, and hyperbilirubinemia.
