When a child develops pneumonia, the symptoms are usually relieved after 3-5 days of fluids, and the results can be seen. However, if the pneumonia is more serious, even if the child is hospitalized for infusion treatment, the child will need to be hospitalized for at least 2 weeks before he or she can fully recover from the pneumonia. If the symptoms of pneumonia are more severe, some children may need to be hospitalized for at least 1 month before they recover completely. Therefore, even if the pneumonia is relieved after 3-5 days of infusion, the treatment should not be stopped at any time, but should be continued until the symptoms of pneumonia have completely recovered, and then the treatment should be stopped. Depending on the type of infection, antibiotics or antiviral medications should be administered intravenously. In addition, if the child’s wheezing is severe, aminophylline can be used to relieve the symptoms of wheezing. If the cough and phlegm are more serious, you can use Ambrotyl oral solution for oral treatment, the effect of cough and expectorant is relatively good.
