IRDS Flashcards
1
Q
Name the components of surfaxin (synthetic surfactant)
A
- phospholipids and a fatty acid (mimicking dppc)
- sinapultide (a small segment of surfactant protein B)
2
Q
Explain the use of corticosteroids for preventing IRDS
A
Used pre-birth to encourage the maturation of lungs, gut, brain, etc
- promotes the development of type 1 and 2 epithelial cells (which increases surfactant production)
3
Q
Define IRDS
A
Infant respiratory distress syndrome. = insufficient surfactant production
4
Q
Signs and Sx?
A
Grunting, cyanosis (turning blue from hypoxia), tachypnea
5
Q
How would fluid clearance from lungs help with IRDS?
A
Clearing the excess fluid will aid gas exchange
6
Q
When is cortisol / corticosteroids indicated?
A
Most effective at 34 weeks or earlier (this is when IRDS is most common)
7
Q
Is ventilation support or ECMO useful in IRDS?
A
Yes
