How to treat a child's bronchitis

Patient's question:

Symptom Description: Cough
Past Treatment and Effect: I received intravenous drips for more than ten days in our county hospital, but there was no improvement. The medications used included penicillin, cephalosporin, and Xixin brain. Later, several changes in medication also failed to yield results. Yesterday, I had a check-up at Qilu Hospital, where 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, including 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 associated with various factors such as low immune function, bronchial foreign bodies, congenital bronchial and pulmonary developmental abnormalities, among others. 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 it 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. In most cases, the majority of children can be cured, with a good prognosis.
