If a newborn develops pneumonia, the approximate length of stay is a situation that needs to be analyzed on a case-by-case basis. First of all, the conventional length of stay is around 10-14 days. In this case, the neonatal pneumonia is mild, the child’s respiratory distress is mild, no ventilator treatment is applied, and there are no specific underlying diseases. In this case, the child is given timely anti-infective treatment, such as the application of cephalosporin or other macrolide drugs, such as erythromycin. Combine with nebulizer inhalation treatment, which includes budesonide, etc., to give the child symptomatic cough and phlegm treatment. The child will be able to be discharged after about 10-14 days of treatment. Next, there is a treatment period greater than 2 weeks. This situation is suitable for neonatal pneumonia is more serious, such as pneumonia lesion area is relatively large, the child also has the underlying disease, the treatment effect is relatively poor, the bacterial infection often belong to drug-resistant bacteria. This is a relatively long course of treatment, often taking longer than 2 weeks.
