How to treat a child's bronchitis

Patient's question:

Medical Description: Cough
Previous Treatment and Effectiveness: I received intravenous drips in our county for over ten days, but there was no improvement. The medications included penicillin, cefalexin, and Xixin Brain. I was also switched to different medications several times, but none of them worked. Yesterday, I had a check-up at Qilu Hospital. The blood tests showed slightly elevated levels of certain blood parameters and myocardial enzymes, but it was not mycoplasma infection. The X-ray results (symmetrical chest cage, central mediastinum and trachea, increased texture, no abnormalities in the heart or diaphragm) and globulin levels were normal. The doctor at Qilu Hospital prescribed some medications for me: Sustiva, Aphanizole, and E.
Help Needed: Doctor, how should I treat my child now?

Doctor's answer:

Chronic bronchitis in children is not caused by a single factor but may be related to various factors such as low immune function, bronchial foreign bodies, congenital bronchial and pulmonary developmental abnormalities. Therefore, once a child is suspected of having chronic bronchitis, it is essential to consider the common factors mentioned above, combined with immune function tests and chest X-ray examinations, to identify the underlying cause. It is crucial to avoid diagnosing the condition as chronic bronchitis in a general manner and blindly using antibiotics for treatment.
Through chest X-ray examinations of children, and even bronchoscopy, once chronic bronchitis and its cause are confirmed, it is necessary to actively remove the underlying cause and combine measures such as anti-infection and symptomatic treatment. The majority of children can be cured, with a good prognosis.
