Is this trial a fit for you?

Likely a good fit

Pregnant people between 24 and 41 weeks gestation diagnosed with severe preeclampsia who do not have chronic lung disease or known heart disease, have BMI ≤ 40, and are not in immediate need of delivery.

Probably not a fit

Patients with chronic lung disease, known cardiac disease, existing diagnosed pulmonary edema at admission, BMI > 40, or those requiring immediate delivery are excluded and may not benefit from this protocol.

What this trial studies

This is a prospective, longitudinal observational study with a diagnostic validation component enrolling patients with severe preeclampsia. Each participant will receive a clinical exam and an eight-zone lung ultrasound to count B-lines, a sonographic sign of interstitial pulmonary edema. Data will be collected at admission, within 24 hours after delivery, and again 7–10 days postpartum to track changes over time. Lung ultrasound findings will be compared with clinical signs and symptoms of volume overload.

Why it matters

Potential benefit: If successful, this approach could provide a fast, noninvasive way to detect and monitor pulmonary edema, helping clinicians treat fluid overload earlier and potentially reduce maternal complications.

How similar studies have gone: Lung ultrasound and B-line counting have shown promise in detecting pulmonary edema in heart failure and some obstetric cohorts, but evidence specific to severe preeclampsia remains limited.
