HYPERBILIRUBINEMIA Flashcards
(15 cards)
- Refers to an excessive level of accumulated bilirubin in the blood
- Characterized by jaundice or icterus
- Common finding in the newborn but in extreme cases, it can indicate
a pathologic state. - It may result from increased unconjugated or conjugated bilirubin
hyperbilirubinemia
possible causes
- physiologic
- breastfeeding
- excess bilirubin
- liver cant secrete conjugated bil
- overproduction and under excretion
- genetics
complications
bilirubin encephalopathy
kernicterus
- a common and typically harmless condition in newborns where the skin and eyes turn yellow due to elevated bilirubin levels in the blood
- most common evidence of hyperbilirubinemia
physiologic jaundice
what phase
bilirubin levels of formula fed infants gradually increase
to approximately 5-6 mg/dl by 2 or 5 days of life then decrease to a
plateau of less than 3 mg/dl by the 5th day
first phase
what phase
:bilirubin maintain a steady plateau without increasing
or decreasing until approximately 12-14 days at which levels
decrease to the normal value of 1 mg/dl
second phase
if it appears within the 1st 24 hours and is caused
by HDN, sepsis or one of the maternally derived diseases such
as diabetes mellitus or infections
pathologic
if it appears on the 2nd or 3rd day, peaks on the
3rs to 5th day, and declines on the 5th to 7th day
physiologic
normal value of unconjugated bilirubin
0.2-1.4 mg/dl
risk factors in term and late preterm
- jaundice within 24 hours after birth
- serum bilirubin high
- rh incompatibility
- hemolytic disease (g6pd)
- ges age 35-36 weeks
- east asian or asian american race
- cephalhematoma
- exclusive BF
- hx of sibling with hyperbilirubinemia
therapeutic mgmt
a. Phototherapy
b. Exchange transfusion
c. Pharmacologic treatment – Phenobarbital
d. Early initiation of feedings
e. Frequent breastfeeding
primary goal
prevent bilirubin encephalopathy and kernicterus
encourage frequent BF preferably every ___ hours
1.5 - 2 hours
this screening tool is now widely used in newborn nurseries and outpatient clinics, offices, and emergency departments to obtain a rapid and non-invasive estimate of the degree of hyperbilirubinemia
transcutaneous bilirubin meter
