T or F: palliative care is the accepted standard approach when < 23 wk GA.
False.
Accepted as standard if = or < 21 wk GA.
If 22-25+6 consult maternal fetal medicine specialist + transfer to tertiary HC centre.
Outcome in neo since surfactant started:
- decreased mortality
- decreased BPD
- increased air leak
- increased IVH
- decreased PDA
Decreased mortality
EBM:
- reduced air leak (pneumo) and mortality from RDS
- reduces morbidity (oxygenation, pneumothorax, pul interstitial emphysema/ PIE, duration on vent support)
- increases likelihood of surviving without BPD largely by improving survival rather than BPD incidence
- Does NOT reduce INCIDENCE of CLD
- NO effect on IVH, BPD, NEC, ROP

- Intubated w/ pul hemm
- Sick + OI > 15
** < 29 wk GA outside tertiary care consider immediate intubation and surfactant after stabilization.
** if significant risk RDS should get propyl. within few min. of intubation
**no benefit to giving more than 3 doses.
T or F: there is benefit in giving surfactant > 3 doses.
False.
T or F: neo intubated w/ RDS should get surfactant before transport.
