The course of neonatal infectious pneumonia is about 5-15 days, but the course of severe neonatal pneumonia can be more than 20 days or even 1 month. The immune function of newborns is not well developed and can easily cause pathogenic bacterial infections, which can lead to pneumonia. If the pneumonia is caused by bacterial infection only, the baby can be discharged from the hospital in about 5-10 days. However, pneumonia caused by mycoplasma or viral infections, or even other serious complications, can take more than 2 weeks to heal and be discharged, even with ventilator-assisted ventilation to prevent death by asphyxia. In addition, other supportive treatments during treatment are also important, including temperature stabilization, fluid balance, and medication. In addition, during the treatment of neonatal pneumonia, physical methods can be used to help cool the child, and parents need to feed the child more water to avoid dehydration. During this period, the amount of breastfeeding is slightly reduced to minimize the burden on the gastrointestinal tract of the child, and the baby needs to be kept warm after discharge from the hospital to avoid getting cold.
