Pneumonia in newborns is not usually associated with jaundice. However, if pneumonia is complicated by sepsis, it can affect the bilirubin level. Neonatal jaundice has two types: physiological jaundice and pathological jaundice. Pathological jaundice is mainly due to abnormally high serum bilirubin levels caused by diseases, such as hemolysis in newborns, cranial hematoma, subcutaneous bruising, prematurity, infection, asphyxia, hypoxia, acidosis, sepsis, hyperthermia, hypoglycemia, liver disease, biliary tract pathology, etc., which are all risk factors for jaundice. Neonatal pneumonia is mainly caused by bacterial, viral, Chlamydia trachomatis and other pathogens infections causing lung inflammation, usually cough, fever, shortness of breath and other symptoms, usually less related to jaundice, but if the pneumonia is complicated by sepsis, it can aggravate the baby’s jaundice. Therefore, it is recommended that if any abnormality occurs in newborns, they should consult the neonatology clinic in time, and under the guidance of doctors to actively carry out treatment.
