When a 28-Week Preterm Infant Needs More Oxygen: Is the PDA Really Driving the Deterioration?
At 21 days, a 28-week infant with rising oxygen needs, a continuous murmur, and pulmonary congestion may have a hemodynamically important PDA—but the murmur is not the diagnosis. This case discussion shows how to separate ductal pulmonary overcirculation from sepsis, evolving lung disease, and pulmonary hypertension, then use echocardiography together with the clinical picture to judge whether closure is likely to help.
