  2. Atrial septal defects
  3. Patent ductus arteriosus
  4. Coarctation (narrowing) of aorta
  5. Aortic valve stenosis

Because there is more pressure on the left side, oxygenated blood will move from left to right (left to right shunt)

54
Q

What are the cyanotic causes of congenital heart disease?

A

Characteristed by right to left shunt, cyanosis starts around 80-85% oxygen

  1. Tetralogy of Fallot

    - Can treat test spells with b-blockers
    - Need cardiac repair surgery
  2. Transposition of the great arteries
    - Most common at birth
    - Pulmonary artery and aorta swap locations (blood on right never gets oxygenated and vice versa)
    - Will lead to death UNLESS there is a patent ductus arterosis, foramen ovale or VSD
    - Can give prostaglandin E to keep ductus arteriosus open until surgery
    - Can lead to congestive heart failure
  3. Tricuspid atresia
    - Tricuspid does not form
55
Q

What is the nitrogen washout test?

A

aka Hyperoxia test

  • Used to differentiate cardiac from non-cardiac causes of cyanosis
  • Give infant 100% oxygen for ten minutes and take ABG; if p02 <15kPa - congenital heart disease
56
Q

What is acrocynaosis?

A
  • Peripheral cyanosis around the mouth and extremities due to benign vasomotor changes
  • Occurs immediately after birth in healthy infants
  • May persist for 24-48h
57
Q

How is patent ductus arteriosus diagnosed and managed?

A
