In your medical description, the infant is a newborn who has repeatedly experienced neonatal jaundice after birth, diagnosed with cystic adenomatoid malformation. Cystic adenomatoid malformation can lead to abnormal lung function, causing tissue hypoxia and resulting in recurrent jaundice. The infant also has a dry cough and vomiting. Pay attention to the possibility of cystic adenomatoid malformation secondary to lung infection, which may be caused by neonatal pneumonia. Infections can also cause jaundice, so be aware of the possibility of neonatal pneumonia.
