Question
A 5-year-old child has been coughing for two months, starting with no phlegm and later producing thin sputum. After taking Chinese medicine for three days, there has been no improvement.
Answer
Continuous coughing for two months requires the exclusion of cough variant asthma, which can be diagnosed using Ventolin as a diagnostic treatment. If it is indeed cough variant asthma, it also needs to be treated according to the standard protocol, using Fuxedion nebulizer inhalation anti-inflammatory treatment.
