Q

Define physiological jaundice

A

Due to high levels of fetal haemoglobin there is high turnover of RBCs resulting in lots of bilirubin leading to mild yellowing of skin and sclera - presents at 2-7 days. Normally resolves within 10 days

24
Q

When does physiological jaundice present

A

2-7 days of life

25
Q

Causes of jaundice - increased bilirubin

A

Haemolytic disease of the newborn
ABO incompatibility
Haemorrhage
Intraventricular haemorrhage
Cephalo-haematoma
Polycythaemia
Sepsis and DIC
G6PD deficiency

26
Q

Causes of jaundice - decreased clearance

A

Prematurity
Breast milk jaundice
Neonatal cholestasis
Extrahepatic biliary atresia
Endocrine - hypothyroid, hypopituitary
Gilbert syndrome

27
Q

Define breast milk jaundice

A

Components of breast milk inhibit processing of bilirubin, more likely to become dehydrated by inadequate feeding, poor feeding leads to slow stools worsening excretion of bilirubin

28
Q

Define haemolytic disease of the newbord

A

Caused by incompatibility between the rhesus antigens on the surface of the red blood cells of the mother and fetus.

29
Q

Investigations in jaundice

A

FBC and film
Bilirubin
Blood typing
Direct coombs test
Thyroid function
Blood and urine cultures
G6PD deficiency

30
Q

Management of jaundice

A

Treatment graphs
Phototherapy
Exchange transfudion

31
Q

When should bilirubin be measured following phototherapy

A

12-18 hours after stopping

32
Q

What is associated with preterm birth

A

Social deprivation
Smoking
Alcohol
Drugs
Over or under weight

33
Q

Short term complications of preterm delivery

A

35
Q

38
Q

Define retinopathy of prematurity

A

Condition affecting preterm babies - abnormal development of blood vessels in the retina can lead to scarring, retinal detachment and blindness.

39
Q

Management of retinopathy of prematurity

Systematically targeting areas of the retina to stop new blood vessels developing
Transpupillary laser photocoagulation
Cryotherapy
Injections of VEGF inhibitors
Surgery for complications

40
Q

Define necrotising enterocolitis

A

NEC is a disorder affecting premature neonates, where part of the bowel becomes necrotic leading to perforation, peritonitis and shock.
