21
Q

Give a cause of neurodevelopmental problems shortly after delivery that requires immediate resuscitation in the newborn

A

Hypoxic ischaemic encephalopathy

Multi-organ damage due to tissue hypoxia

22
Q

List respiratory problems that can be seen in the newborn shortly after delivery

A

Transient tachypnoea of newborn (TTN)

Pneumothorax (spontaneous or secondary to resusc)

23
Q

What is transient tachypnoea of newborn? What is a major risk factor?

A

Inability of the newborn’s lungs to expel or absorb amniotic fluid during and following delivery
Cesarean delivery

24
Q

State a cardiac problem that is a common cause of heart failure in the newborn

A

Hydrops foetalis

25
Q

What is hydrops foetalis?

A

Accumulation of fluid in at least 2 compartments (ascites, pleural effusion, abdominal swelling etc.)

26
Q

What are the two main types of hydrops foetalis?

A

Immune (due to Rhesus disease)

Chromosomal

27
Q

State a cardiac problem that is due to a failure to adapt to postnatal life

A

Persistant pulmonary hypertension of newborn

Pressure in lungs does not drop, causing hypoxia

28
Q

List common cardiac-related congenital diseases found in the newborn

A
Tetralogy of fallot
Transposition of great arteries
Coarctation of aorta
Total anomolous pulmonary venous drainage
Hypoplastic heart
29
Q

What is a common clinic sign of coarctation of aorta?

A

Absent femoral pulses

30
Q

List the main components of tetralogy of fallot

A
"Don't DROP the baby"
Defect (VSD) 
Right ventricular hypertrophy 
Overriding aorta 
Pulmonary stenosis
31
Q

What is total anomolous pulmonary venous drainage (TAPVD)?

A

Four pulmonary veins drain abnormally to the right atrium, instead of the left, by way of an abnormal (anomalous) connection

32
Q

What is hypoplastic heart?

A

Left ventricle is underdeveloped leading to reduced pumping action of the heart

33
Q

Diaphragmatic hernia

34
Q

What is a common sign on imaging of tracheo-oesophageal fistula?

36
Q

State a common renal-related congenital disease found in the newborn
