Premature newborn with respiratory distress

CXR of symmetrical distribution of artificial surfactant in a patient with respiratory distress syndrome
CXR AP obtained just after birth (above left) shows the lungs bilaterally to be relatively clear and hypoexpanded. CXR obtained 4 hours later after intubation (above right) shows interval development of bilateral symmetrical ground glass opacity in the lungs which remain hypoexpanded. CXR obtained 4 hours after the administration of artificial surfactant (below) shows the lungs now to be normally expanded and to be clear of the previously seen ground glass opacities.

The diagnosis was respiratory distress syndrome before and after the symmetrical administration of artificial surfactant.
