Q

What happens to the lungs in respiratory distress syndrome?

A

There is a lack of surfactant so the lungs are non-compliant and stiff. This leads to hypoxia

Q

What is the pathophysiology of retinopathy of prematurity?

A

If O2 is given following an episode of hypoxia then there is proliferation of vessels at the border of vascular and non-vascular retina

  • reduced visual acuity

21
Q

What is hypoxic ischaemic encephalopathy and what does it lead to?

A

prolonged or severe hypoxia leading to ischaemic brain damage
leads to CP

22
Q

How can babies at risk of hypoxic ischaemic encephalopathy be managed?

A

Therapeutic hypothermia - cool to 33 degrees for 72 hours and then rewarm

23

25
Q

What are the causes of small for gestational age?

A
  • Constitutionally small (relating to maternal size, ethnicity)
  • IUGR
26
Q

What are the causes of IUGR?

A

Placenta mediated
- maternal smoking, alcohol, pre-eclampsia, malnutrition, anaemia, infection

Non-placenta mediated
- chromosomal abnormalities, inborn error of metabolism, fetal infection

27
Q

How is a mum/baby with ?SGA monitored and investigated?

A
  • Estimated fetal weight
  • Fetal abdominal circumference
  • Karyotyping
  • TORCH infection screen

28
Q

What are the neonatal signs and symptoms of IUGR?

A 
Hypoglycaemia 
Hypothermia 
Lack of buccal fat
Loose folds of skin
Thin arms and legs - limited fat
29
Q

What can cause persistent neonatal hypoglycaemia?

A
  • infection/ sepsis
  • maternal diabetes
  • IUGR
  • pre-term
  • hypothermia
30
Q

How may a neonate acquire an infection?

A
  • via the placenta
  • via ascending maternal infection
  • via the birth canal/ genitals
  • via breastfeeding
31
Q

What are the most common organisms causing neonatal sepsis?

A

GBS, e.coli, listeria

32
Q

What are the risk factors for neonatal sepsis?

A
  • premature
  • PROM
  • maternal fever >38 or chorioamnionitis
  • maternal GBS colonisation
33
Q

How does neonatal sepsis present?

A

fever + apnoea + hypotonia + poor feeding

34
Q

How is neonatal sepsis managed?

A

Benzylpenicillin + Gentamicin

35
Q

How may neonatal sepsis be prevented?

A

Maternal IV benzylpenicillin if:

  • previous GBS baby

A

meningoencephalitis and seizures

IV aciclovir

37
Q

What parameters form the APGAR score? What is considered a normal score?

Grimace (stimulation = reflex, cry, grimace etc)
Activity (movement vs floppy) 
Respiratory rate

7-10

38
Q

What are the signs and symptoms of biliary atresia? When does it present?

A

Within first 8 weeks:

  • Chalky stool and dark urine
  • Jaundice
  • Hepatomegaly
  • Poor growth
39
Q

What are the signs that a baby may be hypotonic?

A
  • Head lag

  • Myotonic dystrophy
41
Q

What are the advantages and disadvantages of breastfeeding?

A 
\+ free
\+ infection prevention
\+ bonding
\+ further uterine contraction 
\+ protects against obesity, DM and SIDS
  • lacks vitamin D
  • may not get enough food
  • transfer of infections eg HIV
  • maternal breast issues eg mastitis
