Meconium aspiration

A chest radiograph in a newborn born with meconium-stained amniotic fluid exhibits streaky opacities across both lungs. Meconium, which is fetal stool comprised of cellular debris and secretions, has a viscous consistency. When aspirated, it can obstruct small airways. Meconium aspiration is more common in term and post-term neonates.

Frontal radiograph of the chest in a child with dyspnea born at 42 weeks of gestational age and with meconium-stained amniotic fluid shows streaky opacities radiating centrally within the lungs and a small left apical pneumothorax (arrow). Meconium aspiration is a cause of respiratory distress in a newborn. Meconium aspiration can result in airway obstruction leading to areas of both hyperinflation and atelectasis. Immediate complications of meconium aspiration include pneumothorax and pneumomediastinum. Subacute and long-term complications including infection and pulmonary hypertension. #ThoraxThursday #ThoracicThursday

Meconium Ileus on a full term newborn with abdominal distention and no stools for the first 24 hours of life. Wich is the best treatment?

AP (image 1) and lateral (image 2) radiographs of the abdomen show amorphous calcifications (arrowhead) within the left hemiabdomen and a focal dilated loop of bowel in the upper abdomen. Abdominal calcifications in a neonate can be observed in the setting of meconium peritonitis, which occurs after in utero bowel perforation. Meconium peritonitis appears of radiograph with peripheral calcifications. Occasionally, a meconium pseudocyst can develop when extruded meconium becomes walled off.

This a CXR of a neonate ( 1 day) with severe meconium aspiration syndrome, what are the findings ?
