24. Small Group: Neonatal Lung Disease Flashcards
1
Q
what can be caused by lack of surfactant?
A
atelectasis, VQ mismatch, hypoxia, C02 retention.
2
Q
common s/s of infant respiratory failure:
A
tachypnea, retractions, grunting, nasal flaring, decr urine output
3
Q
the ground glass appearance on xray indicates what?
A
alveolar collapse
4
Q
air bronchograms on xray indicate what
A
collapse around airways
5
Q
what do full pulses and wide pulse pressure indicate
A
PDA
6
Q
what is the preferred initial treatment of PDA
A
indomethacin, prostaglandin synthetase inhibitor.
7
Q
why would giving mom steroid prior to birth help the baby?
A
accelerates lung maturity, induces enzymes that stimulate release of surfactant.
8
Q
would we use 100% 02 in this case?
A
no, oxygen toxicity. can collapse alveoli in lungs, cause blindness.
