Flashcards in Neonatal Jaundice Deck (10):

What is the percentage of term neonates which have physiological jaundice in the first week of life?



What is the condition that prolonged jaundice can cause?

Kernicterus-Basal ganglia


Neonatal pathological jaundice is found at

1 day of age


Neonatal prolonged jaundice is found at

14 days of age


What is jaundice?

Bilirubin-red blood cell (albumin) - fetus have high haemoglobin and break down after being able to respirate on their own. RBC’s are then broken down and bilirubin part is transported with albumin to the liver
Liver: unconjugated to conjugated bilirubin → from fat-soluble to water-soluble
Energy and oxygen


What is physiological jaundice?

Days 3-5
Intestines reabsorption of bilirubin: meconium needs to be passed if there is a delay of excretion, bilirubin could be re-absorbed.


How do you evaluate jaundice?

Maternal blood group: to know if mother is rhesus neg or O -/+
Sepsis: a baby fighting sepsis is using their energy stored to do so. So will not have enough energy to remove bilirubin
Bruising: difficult birth. More blood cells are damaged
Gestation: liver of 37w baby is not mature enough to deal with breaking down bilirubin. 37 weeks will have a different chart. Bilirubin levels are plotted in hours
Age of baby: age in hours
Ethnic origin: G6PD -make assessment of ethinic by looking at parents
Feeding history
Passed meconium
Previous sibling: if previous baby has had jaundice and phototherapy


How do you measure jaundice?

Age of baby
Bilirubinometer: sternum of the baby and can only be used in term babies


Risk factors for neonatal jaundice

ABO incompatibility
Rhesus disease


What does phototherapy consist of?

Parental concerns
Eye protection
Temperature control
Dehydration-loose stools
Nutrition and hydration
Mother-infant interaction
Bili blanket
