Chest Flashcards
1
Q
Meconium aspiration
A
Term or post-term
Segmental/subsegmental atelectasis (ropy airspace opacities in the lung bases)
Hyperinflation
Pneumothorax (20-40%)
2
Q
Transient Tachypnea of the Newborn
A
C-section/maternal sedation/diabetes Minor fissure fluid Interstitial edema, predominantly perihilar (perihilar streakiness) Small pleural effusions Peaks at 24 hours Resolve in 72 hours
3
Q
Surfactant deficient disease (SDD)/RDS
A
Granular opacities Hypoinflation 35 week: pneumocyte production by type II pneumocyte Decreased lecythin:sphingomyelin ratio Bell shaped thorax
4
Q
Neonatal pneumonia (GBS)
A
Hypoinflation
Consolidation
5
Q
Neonatal pneumonia (non GBS)
A
Hyperinflation
6
Q
Peristent pulmonary HTN
A
Engorged pulmonary vessels and airspace opacities
7
Q
Respiratory dis
A
8
Q
Surfactant therapy
A
Increased risk of pulmonary hemorrhage and PDA
Post-treatment: Bleb like lucencies.
9
Q
Difference between GBS neonatal pneumonia vs NonGBS neonatal pneumonia
A
GBS neonatal pneumonia: Low lung volume, coarse opacities. Most common.
Non-GBS neonatal pneumonia: High lung volumes and pleural effusion.
