Incidence of Interstitial Alveolar Syndrome on Point-of-Care Lung Ultrasonography in Pre-eclamptic Women With Severe Features: A Prospective Observational Study
Authors' conclusion
We conclude that ultrasonographic pulmonary interstitial syndrome is present in more than half of the women with pre-eclampsia with severe features and correlates with diastolic dysfunction, high blood pressure records, and acute-onset breathlessness.
Study context
- Population

Main finding
As reported in the abstract
B-lines at admission (45/70 vs 25/70 without B-lines; P = .02)
64.3%
B-lines before delivery (46/70 vs 24/70 without B-lines; P = .01)
65.7%
B-lines 24 hours postpartum (41/70 versus 29/70 without B-lines; P = .15)
58.6%
Observational data: associations, not effects.
Further findings
Low to moderate pulmonary fluid burden at admission
- Nearly all patients with low to moderate severity

Diastolic dysfunction on echocardiography
- Diastolic dysfunction (n = 33/70)
- 47.1%
- B-lines among those with diastolic dysfunction
- 32/33
- Correlation of total B-line score with E/e' ratio in diastolic dysfunction (P < .001)
- r = 0.848
B-lines in symptomatic women on admission
- Breathlessness with B-lines (11/11)
- 100%
- Facial puffiness with B-lines (16/16)
- 100%
