If a newborn exhibits symptoms such as fever or difficulty breathing, and pneumonia is suspected, it is essential to take a chest X-ray. Although the child is very young and just born, and despite the presence of certain radiation from the chest X-ray, the pros and cons must be weighed. For the sake of an accurate diagnosis and timely medication treatment, a chest X-ray is necessary. Unlike adult pneumonia, neonatal pneumonia progresses very rapidly. If the medication is not administered promptly and the diagnosis is uncertain, the condition can easily be delayed and progress too quickly. Thus, at this time, concerns about radiation should be set aside, and a chest X-ray is definitely needed. If the chest X-ray does not confirm the diagnosis, even conducting a CT scan might be necessary. It is crucial to clarify the diagnosis quickly and start treatment promptly. Because neonatal pneumonia is truly different from adult pneumonia, it progresses very rapidly and can potentially lead to severe complications like sepsis and shock, which are very dangerous. (Medication should be used under the guidance of a professional doctor.)
