Newborns born less than 28 days old are not recommended to be treated at home once they develop pneumonia and should be seen by a specialist neonatal hospital. Without effective treatment, there is little chance of self-cure. Because of the weak resistance of newborns, it is difficult to confine the lesions and the pathogens are likely to enter the circulation of the newborn through the blood, and in severe cases, intracranial infections, such as meningitis, may occur, so in general neonatal pneumonia cannot heal on its own. Neonatal pneumonia can be caused by infections, including bacteria, viruses, chlamydia, mycoplasma, fungi, etc. If the infection is not controlled in time, complications such as respiratory failure, circulatory failure, sepsis, DIC, shock and meningitis can occur. The baby’s symptoms and ancillary test results need to be combined to help diagnose and treat accordingly. Neonatal pneumonia may also be caused by inhalation, including aspiration of amniotic fluid at birth and breast milk after birth, which varies in severity and may be secondary to infectious pneumonia, and is also something that needs to be closely monitored for changes in condition. In conclusion, neonatal pneumonia, with its rapidly developing pathology and high mortality rate, should not be treated at home or allowed to recover on its own. Also, because pneumonia is a more serious disease in the neonatal period and progresses rapidly, it can easily cause changes in other systems, so it is important to visit a hospital.
