In which days can Physiological Jaundice appear

Appear day 3-5


When does physiological jaundice peak?

Peak- days 4-6


When does physiological jaundice resolve?

Resolve= days 7-10


Name 4 causes of pathological Jaundice

1. Increased haemolysis
3.decreased albuim binding capacity/competition for albuim binding sites
4.lack of or reduction in enzymes and carrier proteins
5.lack of O2 an glucose
6.hepititas or liver damage slow the process of transport
7. Congenital builiary artesia
8.slower bowel motility


What is haemolytic disease?

A disease of the new born, THIS is when red blood cells rupture


What is the physiology of bilirubin?

Billirubin is a product of broke red blood cells. When broken down the RBCs produce unconjugated bllirubin and can only become conjugated if they bind to albumin. some bilirubin of the are still free to circulate and can go to the brain.

the unconjugated bilirubin have to pass through the liver to undergo a process to become conjugated with albumin

the conjugated bilirubin then passes through the gut which is converted into urobilinogen and is excreted in the urine and faeces.


How would u recognise Jaundice, using the NICE guidelines ?

Yellow colouration of skin and eyes caused by increase of unconjugated bilirubin in skin and mucus membranes in mouth. NICE (2016)


What do NICE (2016) suggest that Jaundice is caused by?

raised billirubin levels in the body which is known as hyperbilirubineaemia


With reference, what is the incidence of Jaundice?

Approximately 60% of term and 80% of pre-term babies develop jaundice in the first week of life, after 24hrs old, 10% of breastfed babies are still jaundice at 1 month


what is it about breastfed babies and Jaundice

They are more likely to get physiological Jaundice than bottle-fed babies within the first week of life.


What is prolonged Jaundice?

Jaundice that continues beyond the first 2 weeks , usually harmless but can be indication for serious liver disease


What does hyperbilirubinaemia mean?

when there is a high amount of bilirubin in the blood


What is Clinical Jaundice

visually detectable Jaundice


Significant Hyperbilirubinaemia

An elevation of serum bilirubin to a level requiring treatment (NICE)


What are the causes of Pathological Jaundice (Jaundice before 24 hrs old)

1. Increased haemolysis of red blood cells (Rupture of RBC)

2. Prematurity

3. There are not enough albumin binding sites are there is a decreased albumin binding capacity

4. Lack of oxygen and glucose

5. Hepatitis or liver damage


when will Jaundice be required to be investigated and possibly treated?

if it occurs within 24hrs

if it appears within 48 hours

if SBR continues to rise rapidly between days 3 and four

if Jaundice foes not subside by day 5-6

if jaundice continues after 12-14 days

if SBR is abnormally high

if baby shows signs of being unwell


name the four facts when identifying jaundice in the 1st 24hours

Always pathological

Relates to causes already present at birth, usually blood incompatibility

May have been predicted by maternal antibody levels

SBR rises very quickly and it is a paediatric emergency


Name three facts when trying to identify Jaundice due to infection

SBR tends to rise steadily

Starts to rise related to time of infection

if the infection was an intrauterine infection, the Jaundice may appear 48hrs after birth.


what does it mean if a baby's conjugated bilirubin level greater than 25mcmol/l ?

May indicate serious liver disease.


What is the danger of hyperbuilirubinaemia?

This condition can cause bilirubin to penetrate the membrane that lies between the blood and the brain, and once it has penetrated it can be toxic to the fetus and it's CNS. This can cause long and short term neurological dysfunction.


Dangers of pathological jaundice?

Bilirubin levels are higher than physiological jaundice and they stay higher for longer.

More at risk of brain damage caused by Jaundice (kernicterus). 50% babies with this condition die.


What should u do before discharging the baby and the parents? With ref

Inform parents of neonatal jaundice and what they should do.

How to check their baby for jaundice

Urgency in seek help if Jaundice occurs in the first 24hrs


Midwifery Care for babies with Jaundice

examine the baby for jaundice at every opportunity especially in the first 72 hours.

check the naked baby in bright and preferably natural light. examination of the sclerae, gums and blanched skin is useful across all skin tones.

Check nappy for pale chalky stools and dark urine


How do you measure bilirubin level?

use a transcutaneous bilirubinometer in babies with a gestational age of 35 weeks or more and postnatal age of more than 24 hours

–if a transcutaneous bilirubinometer is not available, measure the serum bilirubin

–if a transcutaneous bilirubinometer measurement indicates a bilirubin level greater than 250 micromol/litre check the result by measuring the serum bilirubin


How would u perform an SBR?

Always use SBR when measuring the bilirubin of a baby with Jaundice in the first 24hours

Always use SBR when measurement when trying to determine the level of bilirubin levels in babies that are less than 35wks.

Always use SBR when measurement if the baby is at or above the relevant treatment threshold for thier postnatal age and all subsequent measurements.


What additional urgent care would you give for a baby with visible jaundice in the first 24hrs?

Do SBR urgently for 2hrs in all babies that is suspected or has jaundice on the first 24hrs of life

Continue to measure SBR, every 6hrs for all babies with suspected or obvious jaundice, in the first 24hrs of life until the level of both:
-Below the treatment threshold
-Stable and or falling


Why is feeding important to Jaundice?

Breast milk speeds passage of meconium, increasing conversion in bowel to conjugated

•Adequate energy is needed for liver function

•Adequate fluid is needed if baby is hot under

•Supplementary fluid should be avoided as this
reduces intake of breast milk. Breastmilk provides adequate fluid


How would you management and treatment of hyperbilirubinaemia

Offer parents or carers information about treatment for hyperbilirubinaemia, including:

• anticipated duration of treatment

• reassurance that breastfeeding, nappy-changing and cuddles can usually continue. Breaks should be for up to 30 minutes NICE (2016)

•Encourage mothers of breastfed babies with jaundice to breastfeed frequently, and to wake the baby for feeds if necessary.

•Provide lactation/feeding support to breastfeeding mothers whose baby is visibly jaundiced


How does phototherapy work physiology?

Phototherapy works by changing bilirubin under the skin from its unconjugated form to non toxic bilirubin products that can be excreted without conjugation by the live


How would you care for a baby receiving photo therapy

frequency of observations
•Regular feeding (breastfeeding preferably)
•Protect eyes
•Nurse baby naked
•Temperature control
